Application | Comment | Organism |
---|---|---|
industry | in a short period of time the organism produces a large amount of tannase in an agricultural byproduct and cheap substrate like wheat bran, so in future, this organism can be applied for commercial tannase production. Broad range of pH and temperature stability of the enzyme can be exploited in various ways for pollution control in the leather industry and bioprocess industry in future | Hyalopus sp. |

Hyalopus sp. | enzyme production is depleted at higher tannic acid concentrations | down |
Hyalopus sp. | organism in liquid submerged fermentation produces maximum extracellular tannase at the end of its exponential phase after 120 h. Wheat bran supports tannase production. 2.5% tannic acid is most suitable for maximum tannase synthesis through solid state fermentation | up |
