RSM-Based Optimization of Fermentation Conditions and Kinetic Studies of Glutamic Acid and Lysine Production by Corynebacterium glutamicum

Optimization of Fermentation Medium for L-lysine Production by Corynebacterium Glutamicum

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 ...

Fermentative Production of Lysine by Corynebacterium glutamicum from Different Carbon Sources

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 also investigated with glucose as a constant carbon source. The production of L-lysine was exam...

Reversal by citrate of the iodoacetate and fluoride inhibition of glutamic acid production by Corynebacterium glutamicum.

Citrate reversal of iodoacetate inhibition of glutamate synthesis is nonmetabolic. Reversal of fluoride inhibition is metabolic, occurring only at low Mg concentrations.

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
