White, powdered, essential amino acid.
Precursors and biosynthesis made in UK.
Biosynthesis & Extraction
Biosynthesized from Corynebacterium glutamicum, through vitamin B1, biotin, ammonium sulphate, glucose as a growth factors.
The fermentation is controlled by regulating pH and oxygen near the neutral point and is carried out with an agitation rate of 350 rpm at 30°e. After 96 hours, the fermentation is terminated and the broths were subjected to separation and purification of L-Lysine by ion exchange technique. Medium containing vitamin B1 12 mg/l, biotin 135 μg/l, ammonium sulphate 17 g/l, glucose 120 g/l, supplemented with inorganic salts, is utilized.
