Abstract
Hyaluronic acid (HA), which is a highly versatile glycosaminoglycan, is widely applied across the fields of food, cosmetics, and pharmaceuticals. It is primary produced through Streptococcus fermentation, but the product presents inherent challenges concerning consistency and potential pathogenicity. However, recent strides in molecular biology have paved the way for genetic engineering, which facilitates the creation of high-yield, nonpathogenic strains adept at synthesizing HA with specific molecular weights. This comprehensive review extensively explores the molecular biology underpinning pivotal HA synthase genes, which elucidates the intricate mechanisms governing HA synthesis. Moreover, it delineates various strategies employed in engineering HA-producing strains.

Abstract
The unique biological and rheological properties make hyaluronic acid a sought-after material for medicine and cosmetology. Due to very high purity requirements for hyaluronic acid in medical applications, the profitability of streptococcal fermentation is reduced. Production of hyaluronic acid by recombinant systems is considered a promising alternative. Variations in combinations of expressed genes and fermentation conditions alter the yield and molecular weight of produced hyaluronic acid. This review is devoted to the current state of hyaluronic acid production by recombinant bacterial and fungal organisms.

Abstract
Uridine diphosphate-glucose dehydrogenase (UGD) is an enzyme that produces uridine diphosphate-glucuronic acid (UDP-GlcA), which is an intermediate in glycosaminoglycans (GAGs) production pathways. GAGs are generally extracted from animal tissues. Efforts to produce GAGs in a safer way have been conducted by constructing artificial biosynthetic pathways in heterologous microbial hosts. This work characterizes novel enzymes with potential for UDP-GlcA biotechnological production. The UGD enzymes from Zymomonas mobilis (ZmUGD) and from Lactobacillus johnsonii (LbjUGD) were expressed in Escherichia coli. These two enzymes and an additional eukaryotic one from Capra hircus (ChUGD) were also expressed in Saccharomyces cerevisiae strains. The three enzymes herein studied represent different UGD phylogenetic groups. The UGD activity was evaluated through UDP-GlcA quantification in vivo and after in vitro reactions. Engineered E. coli strains expressing ZmUGD and LbjUGD were able to produce in vivo 28.4 µM and 14.9 µM UDP-GlcA, respectively. Using S. cerevisiae as the expression host, the highest in vivo UDP-GlcA production was obtained for the strain CEN.PK2-1C expressing ZmUGD (17.9 µM) or ChUGD (14.6 µM). Regarding the in vitro assays, under the optimal conditions, E. coli cell extract containing LbjUGD was able to produce about 1800 µM, while ZmUGD produced 407 µM UDP-GlcA, after 1 h of reaction. Using engineered yeasts, the in vitro production of UDP-GlcA reached a maximum of 533 µM using S. cerevisiae CEN.PK2-1C_pSP-GM_LbjUGD cell extract. The UGD enzymes were active in both prokaryotic and eukaryotic hosts, therefore the genes and expression chassis herein used can be valuable alternatives for further industrial applications.

Abstract
Hyaluronic acid (HA), a unique polysaccharide with excellent Physico-chemical properties, is broadly used in pharmaceutical, biomedical, and cosmetic fields. It is widely present in all vertebrates, certain bacterial strains, and even viruses while it is not found in plants, fungi, and insects. HA is naturally synthesized by a class of integral membrane proteins called Hyaluronic acid synthase (HAS). Thus far, industrial production of HA is carried out based on either extraction from animal sources or large-scale microbial fermentation. The major drawbacks to using these systems are contamination with pathogens and microbial toxins. Recently, the production of HA through recombinant systems has received considerable attention. Plants are eco-friendly ideal expression systems for biopharmaceuticals production. In this study, the optimized human hyaluronic acid synthase2 (hHAS2) sequence was transformed into Nicotiana tabacum using Agrobacterium rhizogenes. The highest rhHAS2 concentration of 65.72 ng/kg (wet weight) in transgenic tobacco hairy roots was measured by the human HAS2 ELISA kit. The HA production in the transgenic hairy roots was verified by scanning electron microscope (SEM) and quantified by the HA ELISA kit. The DPPH radical scavenging activity of HA with the highest concentration of 0.56 g/kg (wet weight) showed a maximum activity of 46%. Gel Permeation Chromatography (GPC) analyses revealed the high molecular weight HA (HMW-HA) with about > 0.8 MDa.

Abstract
Hyaluronic acid (HA) is a biopolymer of repeating units of glucuronic acid and N-acetylglucosamine. Its market was valued at USD 8.9 billion in 2019. Traditionally, HA has been obtained from rooster comb-like animal tissues and fermentative cultures of attenuated pathogenic streptococci. Various attempts have been made to engineer a safe micro-organism for HA synthesis; however, the HA titres obtained from these attempts are in general still lower than those achieved by natural, pathogenic producers. In this scenario, ways to increase HA molecule length and titres in already constructed strains are gaining attention in the last years, but no recent publication has reviewed the main genetic strategies applied to improve HA production on heterologous hosts. In light of that, we hereby compile the advances made in the engineering of micro-organisms to improve HA synthesis.

Abstract
Owing to its outstanding water-retention ability, viscoelasticity, biocompatibility and non-immunogenicity, Hyaluronic acid (HA), a natural linear polymer alternating linked by d-glucuronic acid and N-acetylglucosamine, has been widely employed in cosmetic, medical and clinical applications. With the development of synthetic biology and bioprocessing optimization, HA production via microbial fermentation is an economical and sustainable alternative over traditional animal extraction methods. Indeed, recently Streptococci and other recombinant systems for HA synthesis has received increasing interests due to its technical advantages. This review summarizes the production of HA by microorganisms and demonstrates its synthesis mechanism, focusing on the current status in various production systems, as well as common synthetic biology strategies include driving more carbon flux into HA biosynthesis and regulating the molecular weight (MW), and finally discusses the major challenges and prospects.

Abstract
Hyaluronic acid (HA) is a glycosaminoglycan polymer found in various parts of human body and is required for functions like lubrication, water homeostasis etc. Hyaluronic acid is mostly produced industrially by bacterial fermentation for pharmaceutical and cosmetic applications. This review discusses on the role of membrane proteins involved in synthesis and transport of bacterial HA, since HA is a transmembrane product. The different types of membrane proteins involved, their transcriptional control in wild type bacteria and the expression of those proteins in various recombinant hosts have been discussed. The role of phospholipids and metal ions on membrane proteins activity, HA yield and size of HA have also been discussed. Today with an estimated market of US$ 8.3 billion and which is expected to grow to US$ 15.25 billion in 2026, it is essential to increase the efficiency of the industrial HA production process. So this review also proposes on how those membrane proteins and cellular mechanisms like the transcriptional control can be utilised to develop efficient industrial strains that enhance the yield and size of HA produced.

Abstract
This paper describes the development of a straightforward method for site-directed gene mutagenesis in Streptococcus zooepidemicus, inspired by the mechanism of natural competence regulated by ComX in other streptococci. An alternative sigma factor comX gene was overexpressed from a plasmid in S. zooepidemicus and electrocompetent cells were prepared. As proof of concept, a DNA cassette with two targeting regions flanking a kanamycin resistance gene was spliced in an overlap extension PCR and electroporated. The cassette was then integrated in the genomic DNA by homologous recombination. Next, the gene SeseC_00180 (fibrinogen- and Ig-binding protein precursor) was selected as target for markerless gene deletion and the impact of its loss on the resulting hyaluronan production was determined. The new method of site-directed mutagenesis is significant because it is not necessary to clone the DNA cassette in an auxiliary vector, electroporating it in S. zooepidemicus cells is enough, which allows to bypass the problems with hard to clone DNA sequences and speeds up the whole process of mutation generation in S. zooepidemicus.

Abstract
In the last decades, interest in medical or cosmetic applications of hyaluronic acid (HA) has increased. Size and dispersity are key characteristics of biological function. In contrast to extraction from animal tissue or bacterial fermentation, enzymatic in vitro synthesis is the choice to produce defined HA. Here we present a one-pot enzyme cascade with six enzymes for the synthesis of HA from the cheap monosaccharides glucuronic acid (GlcA) and N-acetylglucosamine (GlcNAc). The combination of two enzyme modules, providing the precursors UDP–GlcA and UDP–GlcNAc, respectively, with hyaluronan synthase from Pasteurella multocida (PmHAS), was optimized to meet the kinetic requirements of PmHAS for high HA productivity and molecular weight. The Mg2+ concentration and the pH value were found as key factors. The HA product can be tailored by different conditions: 25 mM Mg2+ and 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid (HEPES)-NaOH pH 8 result into an HA product with high Mw HA (1.55 MDa) and low dispersity (1.05). Whereas with 15 mM Mg2+ and HEPES–NaOH pH 8.5, we reached the highest HA concentration (2.7 g/L) with a yield of 86.3%. Our comprehensive data set lays the basis for larger scale enzymatic HA synthesis.

Abstract
Bacterial cellulose (BC) based composites have been widely studied in the biomedical field. In this study, the BC/HA (hyaluronic acid) nanocomposites in the pellicle form were directly produced through co-culturing Gluconacetobacter hansenii ATCC 23769 and Lactococcus lactis APJ3 in a novel two-vessel circulating system. The concentration of HA secreted by L. lactis was controlled through adjusting the constant feed rate of glucose. The dynamic growth of the strains revealed that L. lactis was mainly growing within 48 h while G. hansenii started to grow after 48 h. XRD analysis indicated the presence of HA would not affect the crystallinity of cellulose but increase the crystalline sizes. The FESEM images showed that more ribbons within the width of 20-40 nm and larger ribbons between 180 and 360 nm were observed in BC/HA. The strain at break and the water holding capacity of BC/HA increased with the concentration of HA.

Abstract
Hyaluronic Acid (HA) is a biopolymer composed by the monomers Glucuronic Acid (GlcUA) and N-Acetyl Glucosamine (GlcNAc). It has a broad range of applications in the field of medicine, being marketed between USD 1000-5000/kg. Its primary sources include extraction of animal tissue and fermentation using pathogenic bacteria. However, in both cases, extensive purification protocols are required to prevent toxin contamination. In this study, aiming at creating a safe HA producing microorganism, the generally regarded as safe (GRAS) yeast Kluyveroymyces lactis is utilized. Initially, the hasB (UDP-Glucose dehydrogenase) gene from Xenopus laevis (xlhasB) is inserted. After that, four strains are constructed harboring different hasA (HA Synthase) genes, three of humans (hshasA1, hshasA2, and hshasA3) and one with the bacteria Pasteurella multocida (pmhasA). Transcript values analysis confirms the presence of hasA genes only in three strains. HA production is verified by scanning electron microscopy in the strain containing the pmHAS isoform. The pmHAS strain is grown in a 1.3 l bioreactor operating in a batch mode, the maximum HA levels are 1.89 g/L with a molecular weight of 2.097 MDa. This is the first study that reports HA production in K. lactis and it has the highest HA titers reported among yeast.

Abstract
Hyaluronic acid (HA) is a natural polymer with various molecular weights that specify multiple biological roles. Traditionally, HA is obtained from animal waste and conventional pathogenic streptococci. However, there are challenges in these processes such as the presence of exotoxins, hyaluronidase, and viral contamination. In order to reduce these problems, this study was conducted to produce HA using recombinant bacterium that is generally recognized as safe (GRAS), and thereafter increase production through experimental design. At first, some lactic acid bacteria were screened and evaluated for HA production. Accordingly, among the selected bacteria, Lactobacillus acidophilus PTCC1643 produced about 0.25 g HA/L in the 48th hour of cultivation, and was thus selected as an alternative host for heterologous HA production. An expression vector containing HA synthase genes was transformed into L. acidophilus by electroporation. Consequently, HA production increased to 0.4 g/L. Eventually, response surface method (RSM) was used, which increased HA production to 1.7 g/L. This is approximately 7-fold higher than that produced at first. The resulting HA was characterized by FTIR spectroscopy and its molecular weight was estimated using agarose gel electrophoresis. In conclusion, L. acidophilus could be a safe, effective, and novel HA producer with industrial potential and commercial prospects.

Abstract
With rising concerns about sustainable practices, environmental complications, and declining resources, metabolic engineers are transforming microorganisms into cellular factories for producing capsular polysaccharides (CPSs). This review provides an overview of strategies employed for the metabolic engineering of heparosan, chondroitin, hyaluronan, and polysialic acid — four CPSs that are of interest for manufacturing a variety of biomedical applications. Methods described include the exploitation of wild-type and engineered native CPS producers, as well as genetically engineered heterologous hosts developed through the improvement of naturally existing pathways or newly (de novo) designed ones. The implementation of methodologies like gene knockout, promoter engineering, and gene expression level control has resulted in multiple-fold improvements in CPS fermentation titers compared with wild-type strains, and substantial increases in productivity, reaching as high as 100% in some cases. Optimization of these biotechnological processes can permit the adoption of industrially competitive engineered microorganisms to replace traditional sources that are generally toxic, unreliable, and inconsistent in product quality.

Abstract
Performing these improvement on a wild type Streptococcus zooepidemicus which is already capable of high yield HA production would circumvent the common obstacles lies ahead of industrial level fermentative HA production. Having an improved strain and optimized culture media would pave the way for industrial grade HA production with high quality and quantity. HasA gene was amplified and introduced into the wild type Streptococcus zooepidemicus, under the control of Nisin promoter. The HasA over-expression increased the HA production. In order to compensate for molecular weight loss, the glucose concentration was increased to an optimum amount of 90 g/L.
Hyaluronic acid (HA) is a high molecular weight linear polysaccharide, endowed with unique physiological and biological properties. Given its unique properties, HA have unprecedented applications in the fields of medicine and cosmetics. The ever growing demand for HA production is the driving force behind the need for finding and developing novel and amenable sources of the HA producers. Microbial fermentation of Streptococcus zooepidemicus deemed as one the most expeditious and pervasive methods of HA production. Herein, a wild type Streptococcus zooepidemicus, intrinsically expressing high levels of HA, was selected and optimized for HA production. HasA gene was amplified and introduced into the wild type Streptococcus zooepidemicus, under the control of Nisin promoter. The HasA over-expression increased the HA production, while the molecular weight was decreased. In order to compensate for molecular weight loss, the glucose concentration was increased to an optimum amount of 90 g/L. It is hypostatizes that excess glucose would rectify the distribution of the monomers and each HasA molecule would be provided with sufficient amount of substrates to lengthen the HA molecules. Arriving at an improved strain and optimized cultivating condition would pave the way for industrial grade HA production with high quality and quantity.

Abstract
The potential advantages of hyaluronic acid (HA) production by metabolically-engineered Lactococcus lactis is constrained by the lower molecular weight and yield of HA obtained in these strains, compared to natural producers. Earlier studies have correlated lower HA yield with excessive lactate production in L. lactis cultures (Chauhan et al., 2014). In the present study, a three-fold increase was observed in the amount as well as molecular weight of HA produced by recombinant ldh-mutant L. lactis strains. The diversion from lactate production in the ldh-mutant strains resulted in excess ethanol and acetoin production and higher NAD+/NADH ratio in these cultures. The initial NAD+/NADH ratio showed a positive correlation with HA molecular weight as well as with the HA-precursor ratio (UDP-GlcUA/UDP-GlcNAc). The influence of NAD+/NADH ratio on regulation of the concerned metabolic pathways was assessed by transcriptional analysis of key genes having putative binding sites of the NADH-binding transcriptional factor, Rex.

Abstract
Hyaluronic acid, or HA, is a rigid and linear biopolymer belonging to the class of the glycosaminoglycans, and composed of repeating units of the monosaccharides glucuronic acid and N-acetylglucosamine. HA has multiple important functions in the human body, due to its properties such as bio-compatibility, lubricity and hydrophilicity, it is widely applied in the biomedical, food, health and cosmetic fields. The growing interest in this molecule has motivated the discovery of new ways of obtaining it. Traditionally, HA has been extracted from rooster comb-like animal tissues. However, due to legislation laws HA is now being produced by bacterial fermentation using Streptococcus zooepidemicus, a natural producer of HA, despite it being a pathogenic microorganism. With the expansion of new genetic engineering technologies, the use of organisms that are non-natural producers of HA has also made it possible to obtain such a polymer. Most of the published reviews have focused on HA formulation and its effects on different body tissues, whereas very few of them describe the microbial basis of HA production. Therefore, for the first time this review has compiled the molecular and genetic bases for natural HA production in microorganisms together with the main strategies employed for heterologous production of HA.

Abstract
Hyaluronic acid has a wide range of biomedical applications and its commercial value is highly dependent on its purity and molecular weight. This study highlights the utility of aqueous two-phase separation as a primary recovery step for hyaluronic acid and for removal of major protein impurities from fermentation broths. Metabolically engineered cultures of a lactate dehydrogenase mutant strain of Lactococcus lactis (L. lactis NZ9020) were used to produce high-molecular-weight hyaluronic acid. The cell-free fermentation broth was partially purified using a polyethylene glycol/potassium phosphate system, resulting in nearly 100% recovery of hyaluronic acid in the salt-rich bottom phase in all the aqueous two-phase separation experiments. These experiments were optimized for maximum removal of protein impurities in the polyethylene glycol rich top phase. The removal of protein impurities resulted in substantial reduction of membrane fouling in the subsequent diafiltration process, carried out with a 300 kDa polyether sulfone membrane. This step resulted in considerable purification of hyaluronic acid, without any loss in recovery and molecular weight. Diafiltration was followed by an adsorption step to remove minor impurities and achieve nearly 100% purity. The final hyaluronic acid product was characterized by Fourier-transform IR and NMR spectroscopy, confirming its purity.

Abstract
Abstract
Hyaluronic acid (HA), a natural high molecular weight polysaccharide, is produced by Streptococcus zooepidemicus. However, Streptococcus has several drawbacks including its potential to produce exotoxins, so there is demand for an alternative HA source. Here, a recombinant HA biosynthesis operon, as well as the HA biosynthesis operon of S. zooepidemicus were introduced into L. lactis using the nisin-controlled expression system, respectively. HA was successfully synthesized by recombinant L. lactis. Furthermore, overexpression of the endogenous enzymes directing the synthesis of precursor sugars was effective at increasing HA production, and increasing the supply of UDP-activated monosaccharide donors aided synthesis of monodisperse HA polysaccharides. Besides GRAS host strain (L. lactis) and NICE system, the selecting marker (lacF gene) of the recombinant strain is also food grade. Therefore, HA produced by recombinant L. lactis overcomes the problems associated with Streptococcus and provides a source of food-grading HA appropriate for widespread biotechnological applications.

Abstract
HA molecular weight variation in Streptococcus zooepidemicus and two recombinant Lactococcus lactis strains were investigated by chemostat experiments and metabolic flux analysis (MFA). The study showed that intracellular flux ratio of UDP-GlcUA to UDP-GlcNAc correlated directly with HA molecular weight, for all the three strains. The ratio of intracellular concentration of these HA precursors also exhibited a similar trend. Phosphoglucoisomerase activity and glucose flux towards lactic acid formation were found to be the major bottlenecks for HA production in all the three strains. The study suggests that environmental conditions and genetic manipulations that balance the intracellular flux and HA precursors concentrations will result in increased molecular weight.

Abstract
AIMS Corynebacterium glutamicum was tested as an alternative host for heterologous production of hyaluronic acid (HA). METHODS AND RESULTS A set of expression vectors containing hasA, encoding HA synthase from Streptococcus equi subsp. zooepidemicus, alone or in combination with genes encoding enzymes for HA precursor production (hasB, hasC, glmU from Pseudomonas putida KT2440) or bacterial haemoglobin (vgb from Vitreoscilla sp.) was constructed. Recombinant Coryne. glutamicum strains were cultivated in two different minimal media, CGXII and MEK700. HA was isolated from the culture broth by ethanol precipitation or ultrafiltration. Analyses of the isolated HA revealed that overall production was higher in CGXII medium (1241 mg l(-1)) than in MEK700 medium (363 mg l(-1)), but molecular weight of the product was higher in MEK700 (>1·4 MDa) than in CGXII (<270 kDa). Coexpression of hasB, hasC or glmU had no effect on HA yield and did not improve molecular weight of the product. Coexpression of vgb lowered HA yield about 1·5-fold and did not affect molecular weight of the product. Microscopy of negative-stained cultures revealed that Coryne. glutamicum produces no distinct HA capsule. CONCLUSIONS Regulation of cell growth and gene expression level of hasA are reasonable starting points for controlling the molecular weight of HA produced by Coryne. glutamicum. SIGNIFICANCE AND IMPACT OF THE STUDY Corynebacterium glutamicum has a great potential as an alternative production host for HA. The fact that Coryne. glutamicum produces no distinct HA capsule facilitates HA isolation and improves overall yield.

Abstract
Hyaluronan is a polysaccharide with multiple functions in the human body being involved in creating flexible and protective layers in tissues and in many signalling pathways during embryonic development, wound healing, inflammation, and cancer. Hyaluronan is an important component of active pharmaceutical ingredients for treatment of, for example, arthritis and osteoarthritis, and its commercial value far exceeds that of other microbial extracellular polysaccharides. Traditionally hyaluronan is extracted from animal waste which is a well-established process now. However, biotechnological synthesis of biopolymers provides a wealth of new possibilities. Therefore, genetic/metabolic engineering has been applied in the area of tailor-made hyaluronan synthesis. Another approach is the controlled artificial (in vitro) synthesis of hyaluronan by enzymes. Advantage of using microbial and enzymatic synthesis for hyaluronan production is the simpler downstream processing and a reduced risk of viral contamination. In this paper an overview of the different methods used to produce hyaluronan is presented. Emphasis is on the advancements made in the field of the synthesis of bioengineered hyaluronan.

Abstract
Hyaluronic acid (HA) is a natural and linear polymer composed of repeating disaccharide units of β-1, 3-N-acetyl glucosamine and β-1, 4-glucuronic acid with a molecular weight up to 6 million Daltons. With excellent viscoelasticity, high moisture retention capacity, and high biocompatibility, HA finds a wide-range of applications in medicine, cosmetics, and nutraceuticals. Traditionally HA was extracted from rooster combs, and now it is mainly produced via streptococcal fermentation. Recently the production of HA via recombinant systems has received increasing interest due to the avoidance of potential toxins. This work summarizes the research history and current commercial market of HA, and then deeply analyzes the current state of microbial production of HA by Streptococcus zooepidemicus and recombinant systems, and finally discusses the challenges facing microbial HA production and proposes several research outlines to meet the challenges.
