Abstract

Mutant strains ofMycobacterium sp. V-649 producing highly mucous colonies on a solid cultivation medium were prepared after treatment with N-methyl-N′-nitro-N-nitrosoguanidine and production of the exocellular polysaccharide was tested. The strains were cultivated in media with suitable sugar sources under submerged conditions. It was found thatMycobacterium sp. V649/15 produces a maximum of 15–19% polymer after a 5–6-d cultivation. Gas chromatography indicated that the exocellular polysaccharide produced by this strain is of glucan type.
