Multifarious Beneficial Effect of Nonessential Amino Acid, Glycine: A Review.

Glycine is most important and simple, nonessential amino acid in humans, animals, and many mammals. Generally, glycine is synthesized from choline, serine, hydroxyproline, and threonine through interorgan metabolism in which kidneys and liver are the primarily involved. Generally in common feeding conditions, glycine is not sufficiently synthesized in humans, animals, and birds.

Optimization of fermentation upstream parameters and immobilization of Corynebacterium glutamicum MH 20-22 B cells to enhance the production of L-lysine.

L-Lysine is an essential amino acid with high commercial importance, as it has to be available in sufficient quantities in animal and human feeds to meet their nutritional requirement. As there is constant increase in L-lysine demand every year, to meet the increasing demand it is necessary to produce L-lysine in large scale. Generally, L-lysine is produced by batch fermentation.

Comparative studies for the biotechnological production of L-Lysine by immobilized cells of wild-type Corynebacterium glutamicum ATCC 13032 and mutant MH 20-22 B.

Establishing a cost and time efficient approach for bioprocess optimization is desired but is challenging. In the present work, we have addressed the effectiveness of using immobilized cells for aerobic processes, behaviour of immobilized cells, optimization and upstream bioprocess analysis for the production of lysine by immobilized cells of Corynebacterium glutamicum ATCC 13032 and MH 20-22 B in stirred tank bioreactor. Optimized operational conditions for maximal yield and productivity were determined with six parameters i.
