Peptidase with Keratinolytic Activity Secreted by Aspergillus terreus During Solid-State Fermentation
The aim of this study was to evaluate peptidase production by Aspergillus terreus in solid-state bioprocess and evaluate its parameters. The best conditions were 5.0 g of wheat bran as substrate, incubation temperature 30°C, inoculum 2.0x10 spores/g and 75% saline volume, with production reaching 677 U/mL (5400 U/g culture medium) after 72 h of fermentation. Biochemical characterization of the ...
متن کاملPHYTASE PRODUCTION BY Aspergillus niger AND Aspergillus terreus IN SOLID STATE FERMENTATION USING WHEAT BRAN
Animal nutrition industry demands for phytases with high specific activity and stability under high temperature conditions (feed pellet production) and under acidic conditions (monogastric animals), for this reason continues to stimulate the search for new enzyme sources [1]. Most of scientific work has been focused on Aspergillus spp. phytases due to their biochemical properties found [2]. An ...
متن کاملSolid 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...
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 کاملLovastatin Production by Aspergillus terreus Using Agro-Biomass as Substrate in Solid State Fermentation
Ability of two strains of Aspergillus terreus (ATCC 74135 and ATCC 20542) for production of lovastatin in solid state fermentation (SSF) using rice straw (RS) and oil palm frond (OPF) was investigated. Results showed that RS is a better substrate for production of lovastatin in SSF. Maximum production of lovastatin has been obtained using A. terreus ATCC 74135 and RS as substrate without additi...
