Removal of phenolic inhibitors from lignocellulose hydrolysates using laccases for the production of fuels and chemicals. Biotechnol Prog 2024; 40:e3406. [PMID: 37964692 DOI: 10.1002/btpr.3406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 10/14/2023] [Accepted: 10/23/2023] [Indexed: 11/16/2023]
Abstract
Lignocellulose is the most abundant biopolymer in the biosphere. It is inexpensive and therefore considered an attractive feedstock to produce biofuels and other biochemicals. Thermochemical and/or enzymatic pretreatment is used to release fermentable monomeric sugars. However, a variety of inhibitory by-products such as weak acids, furans, and phenolics that inhibit cell growth and fermentation are also released. Phenolic compounds are among the most toxic components in lignocellulosic hydrolysates and slurries derived from lignin decomposition, affecting overall fermentation processes and production yields and productivity. Ligninolytic enzymes have been shown to lower inhibitor concentrations in these hydrolysates, thereby enhancing their fermentability into valuable products. Among them, laccases, which are capable of oxidizing lignin and a variety of phenolic compounds in an environmentally benign manner, have been used for biomass delignification and detoxification of lignocellulose hydrolysates with promising results. This review discusses the state of the art of different enzymatic approaches to hydrolysate detoxification. In particular, laccases are used in separate or in situ detoxification steps, namely in free enzyme processes or immobilized by cell surface display technology to improve the efficiency of the fermentative process and consequently the production of second-generation biofuels and bio-based chemicals.

Effect of Laccase Detoxification on Bioethanol Production from Liquid Fraction of Steam-Pretreated Olive Tree Pruning. FERMENTATION-BASEL 2023.

Abstract
During lignocellulosic bioethanol production, the whole slurry obtained by steam explosion is filtered, generating a water-insoluble fraction rich in cellulose which is used for saccharification and ethanol fermentation, as well as a liquid fraction containing solubilised glucose and xylose but also some inhibitory by-products (furan derivatives, weak acids and phenols), which limits its use for this purpose. Since utilization of this liquid fraction to ethanol is essential for an economically feasible cellulosic ethanol process, this work studied a laccase from Myceliophthora thermophila to detoxify the liquid fraction obtained from steam-pretreated olive tree pruning (OTP) and to overcome the effects of these inhibitors. Then, the fermentation of laccase-treated liquid fraction was evaluated on ethanol production by different Saccharomyces cerevisiae strains, including the Ethanol Red, with the capacity to ferment glucose but not xylose, and the xylose-fermenting recombinant strain F12. Laccase treatment reduced total phenols content by 87% from OTP liquid fraction, not affecting furan derivatives and weak acids concentration. Consequently, the fermentative behavior of both Ethanol Red and F12 strains was improved, and ethanol production and yields were increased. Moreover, F12 strain was capable of utilizing some xylose, which increased ethanol production (10.1 g/L) compared to Ethanol Red strain (8.6 g/L).

Abstract
The rising global population and worldwide industrialization have led to unprecedented energy demand that is causing fast depletion of fossil reserves. This has led to search for alternative energy sources that are renewable and environment friendly. Use of lignocellulosic biomass for energy generation is considered a promising approach as it does not compete with food supply. However, the lignin component of the biomass acts as a natural barrier that prevents its efficient utilization. In order to remove the lignin and increase the amount of fermentable sugars, the lignocellulosic biomass is pretreated using physical and chemical methods which are costly and hazardous for environment. Moreover, during the traditional pretreatment process, numerous inhibitory compounds are generated that adversely affect the growth of fermentative microbes. Alternatively, biological methods that use microbes and their enzymes disrupt lignin polymers and increase the accessibility of the carbohydrates for the sugar generation. Microbial laccases have been considered as an efficient biocatalyst for delignification and detoxification offering a green initiative for energy generation process. The present review aims to bring together recent studies in bioenergy generation using laccase biocatalyst in the pretreatment processes. The work provides an overview of the sustainable and eco-friendly approach of biological delignification and detoxification through whole-cell and enzymatic methods, use of laccase-mediator system, and immobilized laccases for this purpose. It also summarizes the advantages, associated challenges, and potential prospects to overcome the limitations.

Abstract
Although Trametes versicolor is one of the most investigated white-rot fungi, the industrial application of this fungus and its metabolites is still far from reaching its full potential. This review aims to highlight the opportunities and challenges for the industrial use of T. versicolor according to the principles of circular bioeconomy. The use of this fungus can contribute significantly to the success of efforts to valorize lignocellulosic waste biomass and industrial lignocellulosic byproducts. Various techniques of T. versicolor cultivation for enzyme production, food and feed production, wastewater treatment, and biofuel production are listed and critically evaluated, highlighting bottlenecks and future perspectives. Applications of T. versicolor crude laccase extracts in wastewater treatment, removal of lignin from lignocellulose, and in various biotransformations are analyzed separately.

Immobilization of Laccase on Magnetic Nanoparticles and Application in the Detoxification of Rice Straw Hydrolysate for the Lipid Production of Rhodotorula glutinis. Appl Biochem Biotechnol 2020; 193:998-1010.

Abstract
The production of microbial lipid using lignocellulosic agroforestry residues has attracted much attention. But, various inhibitors such as phenols and furans, which are produced during lignocellulosic hydrolysate preparation, are harmful to microbial lipid accumulation. Herein, we developed a novel detoxification strategy of rice straw hydrolysate using immobilized laccase on magnetic Fe3O4 nanoparticles for improving lipid production of Rhodotorula glutinis. Compared with free laccase, the immobilized laccase on magnetic nanoparticles showed better stability, which still retained 76% of original activity at 70 °C and 56% at pH 2 for 6 h. This immobilized laccase was reused to remove inhibitors in acid-pretreated rice straw hydrolysate through recycling with external magnetic field. The results showed that most of phenols, parts of furans, and formic acids could be removed by immobilized laccase after the first batch. Notably, the immobilized laccase exhibited good reusability in repeated batch detoxification. 78.2% phenols, 43.8% furfural, 30.4% HMF, and 16.5% formic acid in the hydrolysate were removed after the fourth batch. Furthermore, these detoxified rice straw hydrolysates, as substrates, were applied to the lipid production of Rhodotorula glutinis. The lipid yield in detoxified hydrolysate was significantly higher than that in undetoxified hydrolysate. These findings suggest that the immobilized laccase on magnetic nanoparticles has a potential to detoxify lignocellusic hydrolysate for improving microbial lipid production.

Abstract
The physicochemical pretreatment is an important step to reduce biomass recalcitrance and facilitate further processing of plant lignocellulose into bioproducts. This process results in soluble and insoluble biomass fractions, and both may contain by-products that inhibit enzymatic biocatalysts and microbial fermentation. These fermentation inhibitory compounds (ICs) are produced during the degradation of lignin and sugars, resulting in phenolic and furanic compounds, and carboxylic acids. Therefore, detoxification steps may be required to improve lignocellulose conversion by microoganisms. Several physical and chemical methods, such as neutralization, use of activated charcoal and organic solvents, have been developed and recommended for removal of ICs. However, biological processes, especially enzyme-based, have been shown to efficiently remove ICs with the advantage of minimizing environmental issues since they are biogenic catalysts and used in low quantities. This review focuses on describing several enzymatic approaches to promote detoxification of lignocellulosic hydrolysates and improve the performance of microbial fermentation for the generation of bioproducts. Novel strategies using classical carbohydrate active enzymes (CAZymes), such as laccases (AA1) and peroxidases (AA2), as well as more advanced strategies using prooxidant, antioxidant and detoxification enzymes (dubbed as PADs), i.e. superoxide dismutases, are discussed as perspectives in the field.

Abstract
A comparative study was performed on Trichoderma harzianum and a combination of Candida boidinii/Bacillus pumilus to reduce the polluting effect of TOPW (Table Olive Processing Water) from the Spanish style. A 2k fractional design was used to study the effect of pH (6–11 for the fungus and 6–9 for Candida/Bacillus), temperature (10–35 °C) and duration (7–14 days for Candida/Bacillus and 14–21 days for T. harzianum), and the effect on phenol reduction, COD and color was evaluated. The experiments were also performed on diluted TOPW (dilution ratio 1:1). Generally, Trichoderma removed higher amounts of phenols and reduced COD more than the combination Candida/Bacillus, thus confirming the higher efficiency of filamentous fungi reported in the literature. The dilution of TOPW had an effect only on COD reduction; however, the effect was mild, at least for T. harzianum (4%), while yield increase was 9% for Bacillus/Candida. pH acted in a different way on phenol removal and COD reduction; an increase of pH caused a reduction of efficiency for COD, while the effect was positive for phenols.

Abstract
New age micro-pollutants, bisphenol-A (BPA) and triclosan (TCA), known for their carcinogenic effects in living organisms can effectively be removed from water using laccase from Trametes versicolor. Laccase was produced from T. versicolor JSRK13 in both submerged and solid-state fermentation (SmF and SSF) conditions. In SmF, T. versicolor JSRK13 gave the maximum production of laccase on the 10th day with an activity of 22 U mL- 1, whereas, in SSF 185 U g- 1 of the enzyme was produced on the 17th day. Maximum production of laccase was observed with Parthenium as substrate. Parthenium, with a particle size of 3-5 mm having 60% moisture was found to be a suitable substrate for laccase production and simultaneous transformation (LPST) of BPA in a synergistic manner. A one-step concentration using 85% ammonium sulphate followed by dialysis was sufficient to give 6.7-fold purification of laccase from the crude culture filtrate. Transformation of BPA was achieved in both SmF and SSF conditions along with the production of laccase, whereas TCA was degraded with free enzyme only. Above 90% of BPA (55-5 mg L- 1) was degraded using the LPST strategy with HBT acting as a mediator in the reaction. LPST strategy did not work for TCA as it completely inhibits the growth of T. versicolor JSRK13. TCA was degraded up to 75% (1.5-0.375 mg L- 1) by the free enzyme. Our study of simultaneous laccase production and transformation proved to be efficacious in case of BPA. The results indicate that industrial and sewage wastewater containing BPA can potentially be treated with T. versicolor JSRK13 laccase. The described strategy can further be used to develop a bioprocess which can work both on solid and liquid wastes containing BPA.
