Abstract

PURPOSE: To collect the titled substance from a culture medium, by cultivating a variant strain, belonging to the genus Brevibacterium, etc., and having the enzymic activity of syntheszing citric acid 1.4 times or more that of the parent strain and the ability to produce the titled substance.
CONSTITUTION: A variant strain, e.g. Brevibacterium flavum (FERM-P No. 5332 or 5333) or Corynebacterium glutamicum (FERM-P No. 5342 or 5343), is cultivated. The variant strain is obtained by bringing the parent strain into contact with N-methyl-N'-nitro-N-nitrosoguanidine, etc. The variant strain has the enzymic activity of synthesizing citric acid 1.4 times or more that of the parent strain, and is cultivated in an ordinary culture medium containing a carbon source, nitrogen source, inorganic ions, etc. to collect the L-proline from the culture fluid by an ion exchange resin, etc.
