چکیده مقاله:

: World population has been continuously raised and therefore due to this fact new source of foods, particularly proteins, are in demand. In recent years, single cell protein has been considered as an accepted substitute for animal and plant proteins. In this study, single cell protein production was studied in a batch submerged culture using Aspergillus niger PTCC5012. Experimental design was performed by Qualitek-4 software using Taguchi as a fractional factorial statistical method.  Glucose, magnesium sulfate and potassium hydrogen phosphate concentrations as well as the pH were considered to be the four key parameters, each one at four different levels. Optimal conditions were created to achieve the maximum single cell protein of Aspergillus niger PTCC5012 in respect of the optimum concentrations of the mentioned parameters. An acceptable consistency of 94% was observed between optimum single cell protein proposed by the software and the experimentally measured one. Glucose concentration was evaluated as the most effective parameter on single cell protein production yield with 40.95% contribution. The concentration of potassium hydrogen phosphate was introduced as the less effective factor on single cell protein production with 13.99% contribution

Production and optimization of phytase by Aspergillus niger

The present article implies an extracellular phytase production by Aspergillus niger under submerged and solid fermentation. Physical and Chemical conditions tested for optimal production of phytase using the single variable mode optimization technique. A considerable higher phytase production was obtained using rice bran as solid substrate (17.8 U/ml & 28.6 U/ml) at pH 5, on 4 day of incubatio...

β-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...

Solid State Fermentation for Production of Chitosan by Aspergillus Niger

The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
