The induction of pigmentation change in a non-acid-fast strain ofMycobacterium phlei by ultraviolet radiation
Five scotochromogenic mutants and 11 achromogenic mutants were induced by UV irradiation of the non-acid-fast photochromogenic PN strain ofMycobacterium phlei. Spontaneous scotochromogenic andExpand

Production of exopolysaccharide by a new mutant strain ofAchromobacter delicatulus using whey fermentation
A novel mutant strain ofAchromobacter delicatulus was cultivated in a 75-L fermentor, using whey as carbon source and production of exocellular glucan was measured. The fermentation had a biphasicExpand

Mapping of the chromosome ofMycobacterium phlei by means of mutagenesis of the replication point
The aim of the present work was to construct a replication map of the chromosome ofMycobacterium phlei. The method of mutagenesis of the replication point by means of nitrosoguanidine was applied toExpand

The mutagenic effect of ethyl methanesulfonate on a non-acid-fast strain ofMycobacterium phlei
Ethyl methanesulfonate was used for the induction of three types of mutants in a non-acidfast strain ofMycobacterium phlei. A total of 20 auxotrophie mutants was isolated. The mutants were isolatedExpand
