Alpha-AGH (R&D Naturals)

Alpha_AGHL-Arginine

Description
White, powdered, conditionally essential amino acid.
Origin
Precursors and biosynthesis made in UK.
Biosynthesis & Extraction
Biosynthesized from the precursor L-Glutamic acid through ornithine and citrulline. Corynebacterium (Brevibacterium) is utilized as a strain for its strong biosynthetic pathway to L-Arginine.
Quality Control
The fermentation is controlled by regulating pH near the neutral point. Advanced purification methods are utilized in order to obtain highly pure L-Arginine from the fermentation broth. Bacterial cells and proteins are removed by means of a membrane or centrifugation, and impurities are removed by means of an ion-exchange resin or activated carbon. Extremely purified L-Arginine crystals is obtained through concentration at the end of the process.

L-Lysine

Description
White, powdered, essential amino acid.
Origin
Precursors and biosynthesis made in UK.
Biosynthesis & Extraction
Biosynthesized from Corynebacterium glutamicum, through vitamin B1, biotin, ammonium sulphate, glucose as a growth factors.
Quality Control
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.
