Studies on the production of L-arginine by fermentation using mutants of Corynebacterium (Brevibacterium), Bacillus, and Serratia have been conducted since the 1960s. More recently, the breeding of L-arginine production strains by gene recombination techniques using Escherichia coli has been investigated. To produce L-arginine efficiently by fermentation, it is necessary to breed strains with a...

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...

Strains representing the taxa Curtobacterium, Brevibacterium saperdae, B. testaceum, Corynebacterium betae, Cor. nebraskense and Cor. oortii were degraded by acid methanolysis and the non-hydroxylated fatty acid esters released were examined by thin-layer and gas-liquid chromatography. The major fatty acids in all strains were 12-methyltetradecanoic (anteiso C15) and 14-methylhexadecanoic (ante...

The effects of combinations of organic amendments, phytochemicals, and plant-growth promoting rhizobacteria on tomato (Lycopersicon esculentum) germination, transplant growth, and infectivity of Meloidogyne incognita were evaluated. Two phytochemicals (citral and benzaldehyde), three organic amendments (pine bark, chitin, and hemicellulose), and three bacteria (Serratia marcescens, Brevibacteri...

A new enantiomer-selective amidase active on several 2-aryl propionamides was identified and purified from a newly isolated Rhodococcus strain. The characterized amidase is an apparent homodimer, each molecule of which has an Mr of 48,554; it has a specific activity of 16.5 g,mol of S(+)-2-phenylpropionic acid formed per min per mg of enzyme from the racemic amide under our conditions. An oligo...
