Threonine production by dihydrodipicolinate synthase-defective mutants of Brevibacterium flavum.
A novel type of threonine-producing strains, dihydrodipicolinate synthase (DPS)-defective mutants of Brevibacterium flavum, was isolated as alpha-amino-beta-hydroxyvaleric acid (AHV)-resistant producers. The third selection markers used were a strong lysine inhibition of threonine production and a lower production of lysine than that of threonine in those derived from strains with feedback-sens...
متن کاملCharacterization of Brevibacterium spp. from clinical specimens.
Nonfermenting coryneform bacteria identified as Brevibacterium spp. were isolated from routine clinical specimens. Four strains were derived from peritoneal fluid and has presumably been involved in the pathogenesis of continuous ambulatory peritoneal dialysis peritonitis. Another five isolates most probably represented skin contaminants. Cell wall and lipid analyses confirmed the genus identif...
متن کاملPhenotypic Characterization of Ligamentum Flavum Cells from Patients with Ossification of Ligamentum Flavum
PURPOSE The objective of this study was to determine the phenotypic characterization of ligamentum flavum cells from patients with ossification of the ligamentum flavum (OLF). MATERIALS AND METHODS Ligamentum flavum tissues were harvested from OLF and non-OLF patients during surgery. OLF and non-OLF cells were isolated from explant cultures. Cultured cells were analyzed using immunofluorescen...
متن کاملCharacterization of cholesterol oxidase from Streptomyces hygroscopicus and Brevibacterium sterolicum.
The FAD-containing enzyme cholesterol oxidase catalyzes the oxidation and isomerization of 3beta-hydroxysteroids having a trans double bond at delta5-delta6 of the steroid ring backbone to the corresponding delta4-3-ketosteroid. Two representative enzymes of this family, namely cholesterol oxidase from Streptomyces hygroscopicus (SCO) and the recombinant enzyme from Brevibacterium sterolicum (B...
متن کاملOptimization 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...
