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 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...
متن کاملManganese transport in Brevibacterium ammoniagenes ATCC 6872.
Uptake of manganese by Brevibacterium ammoniagenes ATCC 6872 was energy dependent and obeyed saturation kinetics (Km = 0.65 microM; Vmax = 0.12 mumol/min per g [dry weight]). Uptake showed optima at 27 degrees C and pH 9.5. 54Mn2+ accumulated by the cells was released by treatment with toluene or by exchange for unlabeled manganese ions, via an energy-dependent process. Co2+, Fe2+, Cd2+, and Zn...
متن کاملProduction 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.
متن کاملmolecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
