Biochemical Changes in the Fermentation Medium During L-methionine Production by Brevibacterium roseum SXS2470

Influence of Oxygen and pH on Methanethiol Production from l-Methionine by Brevibacterium linens CNRZ 918.

The effects of dissolved oxygen concentration and pH on the growth of Brevibacterium linens CNRZ 918 and its production of methanethiol from l-methionine were investigated. Optimal specific methanethiol production was obtained at 25% saturation of dissolved oxygen and at a pH between 8 and 9, whereas optimal cell growth occurred at 50% oxygen saturation and when the pH was maintained constantly...

Optimization of parameters for α-amylase production under solid state fermentation by Trichothecium roseum

The production of extracellular α-amylase by Trichothecium roseum was studied in solid state fermentation (SSF). The effects of wheat bran (WB), rye straw (RS), corncob leaf (CL), sunflower oil meal (SOM) and rice husk (RH) were examined. WB exhibited the highest enzyme production. The appropriate moisture level, incubation period, moistening agent, incubation temperature, inoculum level and pa...

Optimization of Fermentation Medium for L-lysine Production by Corynebacterium Glutamicum

Corynebacterium glutamicum is an industrially important microorganism used for amino acids production. The present work describes the production of L-lysine from Corynebacterium glutamicum IIB-C9 through submerged fermentation process. Fifteen fermentation media were screened in this study for L-lysine production. Out of these fifteen media, FM:13 was found a best one for maximum production of ...

Medium optimization for production of L-Glutaminase (EC 3.5.1.2) by Streptomyces griseus under submerged fermentation

L-Glutaminase is widely distributed in microorganisms including bacteria, yeast and fungi. The enzyme mainly catalyzes the hydrolysis of γ-amido bond of l-glutamine. In this report medium optimization was conducted through one -factor -at -a -time approach for the submerged production of L-Glutaminase by Streptomyces griseus using different additional carbon, nitrogen, amino acids, mineral salt...
