ABSTRACT- Production of lysine by Corynebacterium glutamicum (PTCC 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. For this purpose, ammonium sulphate was selected as a constant nitrogen source. The effect of different nitrogen sources was
Abstract Since the discovery of Gram-positive bacterium Corynebacterium glu- tamicum over a half century ago, amino acid fermentation has been one of the larg- est microbial-based industries, with L-glutamic acid and L-lysine accounting for the majority of amino acids produced. After considerable effort at generating over
22 Nov 2006 The main difference between L-lysine produced for human consumption and that produced for animal feed is the level of biological step must be introduced in production, preventing the appearance of the D-Lysine stereoisomer The Ohio State University. ohioline.osu.edu/aex-fact/pdf/0715.pdf.
A simple and cheap method of lysine production was developed which can be exploited on commercial scale to save foreign exchange. In present study lysine was produced at mass scale in 10 litre flask with 5 litre fermentation medium having pre-treated molasses (15 brix) as substrate by Brevibacterium flavum. Lysine
19 Dec 2017 Request (PDF) | Fermentative product | Since the 1950s the production of amino acids by fermentative methods has become a very important aspect of industrial microbiology, leading to numerous studies to understand and improve the metabolic conditions driving to amino acid overproduction.

The production of lysine by fermentation was studied, using a homoserine-deficient and aminoethylcysteine-resistant strain of Corynebacterium glutamicum, in 1 -dm3 shake flasks and a 14-dm3 laboratory fermentor. Molasses was used as substrate. Superphosphate-treated black strap molasses gave better lysine

The 1950s were the early days of synthesis of amino acids from microbial origin. Two-step methods of production were developed for at least two amino acids-glutamic acid and lysine. In the case of glutamic acid, one specie; of microbe was used to produce o-ketoglutarate, the immediate precursor of. L-glutamic acid, from
