Penicillin amidase production by bacillus megaterium
Biotechnology and Bioengineering, 1973AbstractPenicillin amidase, an enzyme which hydrolyzes benzylpenicillin to 6‐aminopenicillanic acid and phenylacetic acid, is produced by Bacillus megaterium ATCC 14945 as an extracellular enzyme. We used this system as a model to examine the effects of nitrogen, sulfur, and phosphorous limitation on enzyme production in continuous culture.

Streptomycin resistance in Bacillus megaterium
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1971Abstract Spontaneous mutation rates to streptomycin (SM) resistance were measured for dormant B. megatarium spores and for spores at different times into germination. The number of SM-resistant colonies which formed increased with time into germination, although there was no simultaneous increase in the size of the population.

Antimicrobial activity of Bacillus megaterium strains
Microbiology, 2012A bacterial strain with a high level of antimicrobial activity was isolated from soil and identified as Bacillus megaterium. Production of antibiotics by nine strains of this species from the collection of the State Research Institute for Genetics and Selection of Industrial Microorganisms was investigated.

Megacinogenic plasmid from Bacillus megaterium 216
Molecular and General Genetics MGG, 1980Ability to produce megacin A, a bacteriocin of B. megaterium, was transferred from the strain B. megaterium 216 into auxotrophic derivatives of the strain B. megaterium KM via protoplast fusion and polyethylene-glycol-induced protoplast transformation by plasmid DNA, respectively. A 30.9 megadalton plasmid was detected in cells with MegA phenotype, and

Temperature range variants of Bacillus megaterium
Archives of Microbiology, 1977Facultatively and obligately thermophilic variants were isolated from 3 out of 12 tested mesophilic Bacillus megaterium strains. The variants occurred at a frequency of 10(-8)-10(-9). The ability to grow at elevated temperatures was cured by means of treatment with acridine orange.

Hydroxylation of progesterone by Bacillus cereus and Bacillus megaterium
Archives of Biochemistry and Biophysics, 1958Abstract The introduction of an 11α-hydroxy group into progesterone by two species of Bacillus cereus and of a 15β-hydroxy group into progesterone by Bacillus megaterium has been demonstrated.

Plasmid, 2005
Bacillus megaterium QM B1551 contains seven plasmids. Two are small rolling circle plasmids and five are theta-replicating plasmids with cross-hybridizing replicons that define a new family of very homologous yet compatible theta replicons. Previous sequencing of several of the plasmids has shown genes with high similarity to those on the genomes and ...
