L-Glutamine (R&D Naturals)


White, powdered, nonessential amino acid.
Precursors and biosynthesis made in UK.
Biosynthesis & Extraction
Biosynthesized from coryneform bacterium.
Quality Control
Following start-up inspection, fermentation medium components, and DI water is batched into the fermentor and sterilized for 30 min. Sulphuric acid 125 mg/l, copper sulphate 12mg/l, ferric sulfate lmg g/l, vitamin B 2mg g/l, biotin 2mg/l are utilized. The controlled temperature is 32°C. The PH is controlled on the 24th hour – 7.0 to 7.2. Physical separation of L-Glutamine crystals from biomass using a nanofiltration technology is then utilized.
