Mutation of a Bacillus stearothermophilus Strain for Over-production of Cyclomaltodextrin Glucanotransferase

Cyclomaltodextrin Glucanotransferase의 생산을 위한 Bacillus stearothermophilus 균주의 돌연변이

  • Published : 1992.12.01

Abstract

Bacillus stearothermophilus No.239 isolated from soil was mutated with N-methyl-N'nitro-N-nitrosoguanidine (MNNG) to yield a series of mutants with increasing levels of cyclomalto-dextrin glucanotransferase (EC 2.4.1.19` CGTase) production. After five consecutive mautation steps, a mutant MNNG 8 with about 14 times of CGTase activity than the parent strain was obtained.
