Production of lovastatin by Aspergillus terreus: effects of the C:N ratio and the principal nutrients on growth and metabolite production
Production of lovastatin and microbial biomass by Aspergillus terreus ATCC 20542 were influenced by the type of the carbon source (lactose, glycerol, and fructose) and the nitrogen source (yeast extract, corn steep liquor, and soybean meal) used and the C:N mass ratio in the medium. Use of a slowly metabolized carbon source (lactose) in combination with either soybean meal or yeast extract unde...
متن کاملProduction of cellulase from Aspergillus terreus MS105 on crude and commercially purified substrates
Aspergillus terreus MS105 was originally isolated from soil and screened for cellulase production in the presence of various carbon sources including carboxymethyl cellulose (CMC), avicel, sigmacell, filter-paper and salicin. CMC induced the production of endoglucanase (EG) and filter-paperase while the levels of β-glucosidase (BGL) were increased when salicin was present in the medium. Nature ...
متن کاملRelationship between morphology and itaconic acid production by Aspergillus terreus.
The morphology of filamentous fungi closely correlates with the productivity in submerged culture. Using itaconic acid (IA) production by Aspergillus terreus as a research model, the quantitative relationship between the growth form of A. terreus and IA production was investigated. IA fermentation was scaled up from shake flasks to a 7 L stirred tank bioreactor based on the quantitative relatio...
متن کاملKinetic Modelling of Lovastatin Biosynthesis by Aspergillus Terreus Cultivated on Lactose and Glycerol as Carbon Sources
A kinetic model to describe lovastatin biosynthesis by Aspergillus terreus ATCC 20542 in a batch culture with the simultaneous use of lactose and glycerol as carbon sources was developed. In order to do this the kinetics of the process was first studied. Then, the model consisting of five ordinary differential equations to balance lactose, glycerol, organic nitrogen, lovastatin and biomass was ...
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 ...
