Pharmacology

Glutamine is an Amino Acid.

How it is made

Microbial L-glutamine producers were selected from wild type glutamate-producing coryneform bacteria. A sulfaguanidine resistant mutant of Brevibacterium flavum accumulates 41 g/L Lglutamine in 48 h from 10% glucose. A yield of 44% was achieved by the mutant Brevibacterium flavum AJ3409.

Synthesis: By isolation from sugar beet juice.
