AMB Express 2024; 14:20. [PMID: 38337099 PMCID: PMC10858013 DOI: 10.1186/s13568-024-01672-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 01/20/2024] [Indexed: 02/12/2024] Open
Abstract
Sixteen strains of basidiomycetous yeasts were evaluated for their capability to produce ergothioneine (EGT), an amino acid derivative with strong antioxidant activity. The cells were cultured in either two synthetic media or yeast mold (YM) medium for 72 h, after which cytosolic constituents were extracted from the cells with hot water. After analyzing the extracts via liquid chromatography-mass spectrometry (LC-MS), we found that all strains produced varying amounts of EGT. The EGT-producing strains, including Ustilago siamensis, Anthracocystis floculossa, Tridiomyces crassus, Ustilago shanxiensis, and Moesziomyces antarcticus, were subjected to flask cultivation in YM medium. U. siamensis CBS9960 produced the highest amount of EGT at 49.5 ± 7.0 mg/L after 120 h, followed by T. crassus at 30.9 ± 1.8 mg/L. U. siamensis was also cultured in a jar fermenter and produced slightly higher amounts of EGT than under flask cultivation. The effects of culture conditions, particularly the addition of precursor amino acids, on EGT production by the selected strains were also evaluated. U. siamensis showed a 1.5-fold increase in EGT production with the addition of histidine, while U. shanxiensis experienced a 1.8-fold increase in EGT production with the addition of methionine. These results suggest that basidiomycetous yeasts could serve an abundant source for natural EGT producers.

Abstract
Production of mushroom fruit bodies using farming technology could hardly meet the increasing demand of the world market. During the last several decades, there have been various basic and applied studies on fungal physiology, metabolism, process engineering, and (pre)clinical studies. The fundamental aspects of solid-state cultivation of various kinds of medicinal mushroom mycelia in various types of bioreactors were established. Solid-state cultivation of medicinal mushrooms for their biomass and bioactive metabolites production appear very suitable for veterinary use. Development of comprehensive submerged technologies using stirred tank and airlift bioreactors is the most promising technology for fast and large-scale production of medicinal fungi biomass and their pharmaceutically active products for human need. The potentials initiate the development of new drugs and some of the most attractive over-the-counter human and veterinary remedies. This article is to overview the engineering achievements in solid state and submerged cultivations of medicinal mushrooms in bioreactors.

Abstract
Ergothioneine is a natural and safe antioxidant that plays an important role in anti-aging and the prevention of various diseases. This study aimed to report on a kind of medicinal mushroom of Panus conchatus with great potential for the bioproduction of ergothioneine. The effect of different nutritional and environmental conditions on the growth of Panus conchatus and ergothioneine production were investigated. Molasses and soy peptone were found to promote cell growth of Panus conchatus and enhance ergothioneine accumulation. Adding precursors of histidine, methionine and cysteine could increase ergothioneine production and the highest ergothioneine concentration of 148.79 mg/L was obtained. Finally, the extraction and purification processes were also established to obtain the crude ergothioneine extract for further antioxidant property evaluation. The ergothioneine from Panus conchatus showed high antioxidant activity with good stability in a lower pH environment. This study provided a new strain and process for the bioproduction of ergothioneine.

Abstract
Background Ergothioneine (ERG) is a potent histidine-derived antioxidant that confers health-promoting effects. Only certain bacteria and fungi can biosynthesize ERG, but the ERG productivity in natural producers is low. ERG overproduction through genetic engineering represents an efficient and cost-effective manufacturing strategy. Results Here, we showed that Trichoderma reesei can synthesize ERG during conidiogenesis and hyphal growth. Co-expression of two ERG biosynthesis genes (tregt1 and tregt2) from T. reesei enabled E. coli to generate 70.59 mg/L ERG at the shaking flask level after 48 h of whole-cell biocatalysis, whereas minor amounts of ERG were synthesized by the recombinant E. coli strain bearing only the tregt1 gene. By fed-batch fermentation, the extracellular ERG production reached 4.34 g/L after 143 h of cultivation in a 2-L jar fermenter, which is the highest level of ERG production reported thus far. Similarly, ERG synthesis also occurred in the E. coli strain engineered with the two well-characterized genes from N. crassa and the ERG productivity was up to 4.22 g/L after 143 h of cultivation under the above-mentioned conditions. Conclusions Our results showed that the overproduction of ERG in E. coli could be achieved through two-enzymatic steps, demonstrating high efficiency of the fungal ERG biosynthetic pathway. Meanwhile, this work offers a more promising approach for the industrial production of ERG.

Abstract
Ergothioneine (EGT) is a unique naturally occurring amino acid that is usually biosynthesized by bacteria and fungi. As a food-derived antioxidant and cytoprotectant, it has several physiological benefits and has a wide range of applications in food, medicine, and cosmetics. Traditional production of EGT is mainly through biological extraction or chemical synthesis; however, these methods are inefficient, making large-scale production to meet the growing market demand difficult. Nowadays, the rapid development of synthetic biology has greatly accelerated the research on the EGT production by microbial fermentation. In this paper, the biological characteristics, applications, biosynthesis, separation, and detection methods of EGT were fully reviewed. Furthermore, the approaches and challenges for engineering microbial cells to efficiently synthesize EGT were also discussed. This work provides new ideas and future research potentials in EGT production.
