key role of serine in glutathione transferase functions Frontiers Frontiers | Glutathione S-Transferases: Role

This enzyme was produced by fermentation with various microorganisms, particularly fungi from the Aspergillus and Penicillium genera ( Penicillium roqueforti strain could produce both tannase and GA simultaneously ( Aspergillus awamori strain BTMFW032, under deep fermentation conditions, was able to simultaneously produce GA and tannase, resulting in a 15-fold increase in the yields of both tannase and GA ( Rhodotorula pilimanae A45.2 and Bacillus spheroides have also been noted for their abilities to co-produce GA and tannase, with the latter achieving high efficiency in converting tannic acid to GA (90.80% crystallization), making it the most potent bacterial tannase producer for GA synthesis (Kanpiengjai et al., 2020
