چکیده

in this study the effect of different nitrogen source substrates on the amount of chitosan production by aspergillus niger was investigated. a. niger ptcc 5012 from the persian type culture collection (ptcc) was grown on soy bean, corn seed and canola residues at 30 °c for specified cultivation days under sterilized conditions. chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. the results were shown that soy bean residue at moisture of 37% and 8.40.26 % of nitrogen content produced the highest amount of chitosan (17.0530.95 g/kg of dry substrate), after 12 days of incubation. corn seed residue produced very low amount of chitosan (1.90.4 % of nitrogen content). the chitosan was analyzed by ftir spectroscopy and its spectrum was recorded.

Production of Feruloyl Esterase from Aspergillus niger by Solid-State Fermentation on Different Carbon Sources

A mixture of wheat bran with maize bran as a carbon source and addition of (NH(4))SO(4) as nitrogen source was found to significantly increase production of feruloyl esterase (FAE) enzyme compared with wheat bran as a sole carbon and nitrogen source. The optimal conditions in conical flasks were carbon source (30 g) to water 1 : 1, maize bran to wheat bran 1 : 2, (NH(4))SO(4) 1.2 g and MgSO(4) ...

Production of Glucoamylase by Aspergillus Niger under Solid State Fermentation

In this study, Glucoamylase production by Aspergillus niger was investigated under solid state fermentation using low cost by-products of agricultural processes as substrate. Highest enzyme production was observed when a combination of wheat bran (WB) and corn flour (CF) was used as compared to WB+ rice bran, WB+ rice flour and WB alone. Several compositions of corn flours were experimented. Th...
