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...

The simultaneous determination of L tyrosine and L lysine, by enzyme supported flow injection analysis (FIA) was developed using two enzyme reactors in parallel and a single oxygen electrode. L-Tyrosine and L-lysine were determined using the enzyme Ltyrosinase (EC 1.14.18.1) and L-lysineLY -oxidase (LysOD, EC 1.4.3. -), respectively. When sample solutions were simultaneously injected into the t...

Methionine auxotrophic mutants of Methylophilus methylotrophus AS1 expressing a mutant form of dapA (dapA24) encoding a dihydrodipicolinate synthase desensitized from feedback inhibition by L-lysine, and mutated lysE (lysE24) encoding the L-lysine exporter from Corynebacterium glutamicum 2256, produced higher amounts of L-lysine from methanol as sole carbon source than did other amino acid auxo...

1. The absorption of lysine and two lysine-containing dipeptides was studied in normal and cystinuric subjects by jejunal perfusion. Absorption of each dipeptide was compared with that of its constituent amino acids. 2. In normal subjects lysine was better absorbed from the dipeptide glycyl-L-lysine than from the equivalent amino acid mixture. In cystinuric patients lysine was absorbed very poo...

We have previously reported that weanling rats fed a 20% wheat gluten diet, limiting in lysine and containing no detectable carnitine, have significantly lower levels of carnitine in skeletal and heart muscle than rats receiving adequate dietary lysine. Rats on 20% wheat gluten diets were administered appropriate levels of DL-[6-i*C]lysine, L-[mefhyZ3H]methionine, t-N-[mefhyZ-3H]trimethyl-L-lys...

Abstract Background Pineapple plant ( Ananas comosus ) is one of the largest productions in Asia and its increasing production has generated a huge amount pineapple wastes. stem made up high concentration starch which can potentially be converted into value-added products, including amino acids. Due to demand animal feed grade acids, especially for methionine lysine, utilisation cheap renewable...

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 ...

Highly selective binding of basic amino acids, i.e. lysine, arginine, and histidine, by a negatively charged carboxylatopillar[5]arene (CP5A) is reported. And the complexation behavior of the CP5A host towards lysine metabolites including cadaverine (Cad), acetyl-l-lysine (AcLys) and trimethyl-l-lysine (TMLys) is also described.
