2 Abstract: Tannase, produced from the fungus Aspergillus flavus by submerged fermentation on different medium was studied. Tannic acid 1 had a higher activity of 70 U/g/min in purified form. The process parameter was optimized and higher production of tannase was found at 35°C and 96 hours of incubation with 2% tannic acid. 

Production of Tannase using Aspergillus niger by Submerged Fermentation

The optimum conditions for maximum tannase enzyme production in the Submerged Fermentation (SmF) using Aspergillus niger was obtained with an initial tannic acid concentration of 3% (w/v) at 35°C and a fermentation period of 96h.


Results show that the maximum tannase production found at pH 6 when incubated at 30°C for 96 hrs with tannic acid as carbon source and 0.5% yeast extract as nitrogen source is found.

Isolation Of Tannase Producing Fungi And Optimization Of Culture Conditions For Tannase Production By Fungus tws-3

The tannase also known as tannin acyl hydrolase (TAH, E.C, is a hydrolytic enzyme that acts on tannins. Primary screening for tannase was carried out from different soil samples. Six

Statistical optimization of process parameters for the production of tannase by Aspergillus flavus under submerged fermentation

Production of tannase by Aspergillus flavus using tamarind seed powder as substrate was studied in submerged fermentation and revealed that a maximum tann enzyme production of 139.3 U/ml was obtained at the optimum conditions.

The Optimization of Aspergillus sp. GM4 Tannase Production under Submerged Fermentation

Optimized Production of Tannase from Cashew Testa using Aspergillus niger MTCC 5898

This study investigated the production of tannase by Aspergillus niger CEPC 11 on an abundantly available waste byproduct cashew testa under solid state A. niger growth to find the optimum values of parameters obtained through response surface methodology (RSM).

Optimization of Process Parameters for the Production of Tannase and Gallic Acid by Enterobacter Cloacae MTCC 9125.

The Enterobacter cloacae MTCC 9125 showed maximum tannase production with sodium nitrate and KH 2 PO 4 as nitrogen source and phosphate source respectively and Ca 2+ and Mg 2+ ions were found to be stimulatory for tann enzyme synthesis.

Short Communication: Plant Leaves as Alternative Substrates for Tannase Production by Aspergillus ochraceus, Aspergillus phoenicis and Emericela nidulans Under Solid-State Fermentation

Maximal production of tannases under SSF by Aspergillus ochraceus, Aspergillus phoenicis and Emericela nidulans was obtained using Eucaliptus, Psidium guajava and Punica granatum leaves as substrate,

Culture Conditions for the Production of Tannase from Trichoderma harzianum MTCC 10841

To enhance the production level of the enzyme different culture conditions were optimized and observed that optimum temperature and pH for tannase production was 30 o C and 5.5 respectively, which successfully scaled up to 1.5L at laboratory level.



Optimization of tannase biosynthesis by a newly isolated Rhizopus oryzae

A strain isolated locally and identified as Rhizopus oryzae (RO, IIT KGP) was found to synthesise an extracellular enzyme, tanin acyl hydrolase, showing its degradability of tannic acid to gallic

Studies on Fungal Tannase

Tannase was found in the myceĩium of Aspergillus flavus grown on the medium containing tannic acid as a sole carbon source and showed optimum activity at 50 to 60°C and the optimal and stable pH ranges were found to be at 5.0 to 5.5 for methylgallate.
