Optimization of Glutamic Acid Production by Brevibacterium roseum

Improved CMCase production by Spicellum roseum

Production of S-Methylthioacetate by Brevibacterium linens.

Volatile sulfur compounds production by eight strains of Brevibacterium linens isolated from cheeses was demonstrated: methanethiol, dimethyldisulfide, and 2,3,4-trithiapentane. Four of these strains also produced S-methylthioacetate, an important aroma component of smear-coated cheeses. It is the first demonstrated microbiological production of a thioester.

Microbial production of poly-γ-glutamic acid.

Poly-γ-glutamic acid (γ-PGA) is a natural, biodegradable and water-soluble biopolymer of glutamic acid. This review is focused on nonrecombinant microbial production of γ-PGA via fermentation processes. In view of its commercial importance, the emphasis is on L-glutamic acid independent producers (i.e. microorganisms that do not require feeding with the relatively expensive amino acid L-glutami...

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 Physico-chemical Parameters for Hyper- Production of Lysine by Mutated Strain of Brevibacterium Flavum

Lysine as an essential amino acid supplemented to fulfil the dietary requirement of Poultry feed. In Pakistan all this demand is accomplished by importing lysine for feed sector. Wild Brevibacterium flavum was used to induce mutation by random mutagenesis for hyper production of lysine through fermentation. The highest lysine producing strain (BFENU2) was screened with 21.64 g/L production by m...
