Statistical optimization of process parameters for the production of tannase by Aspergillus flavus under submerged fermentation
Production of tannase by Aspergillus flavus (MTCC 3783) using tamarind seed powder as substrate was studied in submerged fermentation. Plackett-Burman design was applied for the screening of 12 medium nutrients. From the results, the significant nutrients were identified as tannic acid, magnesium sulfate, ferrous sulfate and ammonium sulfate. Further the optimization of process parameters was c...
متن کاملImprovement of tannase production under submerged fermentation by Aspergillus niger FBT1 isolated from a mangrove forest
Aspergillus niger FBT1, a local extracellular strain for tannase production, was isolated from soil collected from Matang Mangrove Forest Reserve in Perak, Malaysia. This fungus strain was cultivated in an Erlenmeyer flask under a submerged fermentation system. Medium compositions play a very important role in enhancing enzyme production during fermentation. The production of tannase by A. nige...
متن کاملOptimization of Various Culture Media for Tannase Production in Submerged Fermentation by Aspergillus flavus
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.
متن کاملXylanase Production under Solid State Fermentation by Aspergillus niger
Central composite orthogonal design was applied to quantify relations of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...
متن کاملInvolvement of Physical Parameters in Medium Improvement for Tannase Production by Aspergillus niger FETL FT3 in Submerged Fermentation
Aspergillus niger FETL FT3, a local extracellular tannase producer strain that was isolated from one of dumping sites of tannin-rich barks of Rhizophora apiculata in Perak, Malaysia. This fungus was cultivated in 250 mL Erlenmeyer flask under submerged fermentation system. Various physical parameters were studied in order to maximize the tannase production. Maximal yield of tannase production, ...
