Optimization 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 کاملStatistical 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 کاملβ-galactosidase Production by Aspergillus niger ATCC 9142 Using Inexpensive Substrates in Solid-State Fermentation: Optimization by Orthogonal Arrays Design
Background: Enzymatic hydrolysis of lactose is one of the most important biotechnological processes in the food industry, which is accomplished by enzyme β-galactosidase (β-gal, β-D-galactoside galactohydrolase, EC 3.2.1.23), trivial called lactase. Orthogonal arrays design is an appropriate option for the optimization of biotechnological processes for the production of microbial...
متن کاملStatistical Optimization of a-Galactosidase Production in Submerged Fermentation by Streptomyces griseoloalbus Using Response Surface Methodology
a-Galactosidase production by a novel actinomycete strain Streptomyces griseoloalbus in shake flask culture was optimized using response surface methodology. Screening of variables to find their relative effect on a-galactosidase production was done using Plackett-Burman design. Out of the eleven factors screened, salinity, magnesium sulphate and temperature were found to influence the enzyme p...
متن کاملScreening and Optimization of Cultural Parameters for an Alkaline Protease Production by Aspergillus Terreus Gr. under Submerged Fermentation
An alkaline protease-producing fungus was screened from potato grown soil fields of Bangalore and identified as Aspergillus terreus gr. based on morphological and microscopic features. The selected growth medium contained casein (1%) as a sole source of carbon and nitrogen. The pH of the medium was adjusted to 10.0 using sodium carbonate in order to isolate alkalophilic fungi. The best process ...
