A strain of C. purpurea has been isolated which will produce L‐tryptophan from indole in submerged culture.

The L‐tryptophan produced is extracellular and in a free form.

Levels of up to 1Β·5 mg/ml of L‐tryptophan have been obtained.

In submerged fermentation of Streptomyces sp. N1 in a shake flask, glucose (3% w/v) and (NH4)2SO4 (0.6% w/v) were found to be suitable for extracellular L-glutamate oxidase (GluOx) (EC.1.4.3.11) production. GluOx production was higher with the addition of further KCl or MgCl2 to the medium within th
