Transduction in Bacillus megaterium

Biochemical and Biophysical Research Communications, 1979
Abstract A bacteriophage, MP13, isolated from the soil on B. megaterium QM B1551 has been found to transduce several auxotrophic markers. Transduction required inactivation of the phage to approximately 0.01% survival with UV light and it was enhanced by the absence of salts that are probably necessary for phage readsorption.

Phosphotransbutyrylase Expression in Bacillus megaterium

Current Microbiology, 2001
The molecular analysis of a genomic region of B. megaterium revealed the presence of a gene coding for the enzyme phosphotransbutyrylase (Ptb). The enzyme activity was measured throughout the different phases of growth in B. megaterium, and its activity was found to be maximal in the late exponential growth phase.

spoVG sequence of Bacillus megaterium and Bacillus subtilis

Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1992
We have sequenced the stage V sporulation specific gene spoVG in both Bacillus megaterium and Bacillus subtilis. The open reading frames encode polypeptides of 96 and 97 residues, respectively, and have an 88.6% amino acid identity. Both genes have putative rho-independent terminators. No significant amino acid or nucleotide homology of either gene was

Energy Conservation in Bacillus megaterium

Biochemical Society Transactions, 1974
1. The respiratory chain energy conservation systems of Bacillus megaterium strains D440 and M have been investigated following growth in batch and continuous culture. Respiratory membranes from these strains contained cytochromes b, aa3, o and b, c, a, o, respecitvely; both readily oxidised NADH but neither showed any pyridine nucleotide ...

Streptomycin resistance in Bacillus megaterium

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1971
Abstract 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.

Hydroxylation of progesterone by Bacillus cereus and Bacillus megaterium

Archives of Biochemistry and Biophysics, 1958
Abstract 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.

Penicillin amidase production by bacillus megaterium

Biotechnology and Bioengineering, 1973
AbstractPenicillin 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.

Antimicrobial activity of Bacillus megaterium strains

Microbiology, 2012
A 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.

Expanding the promoter toolbox of Bacillus megaterium

Journal of Biotechnology, 2019
Over the past decades, Bacillus megaterium has gained significant interest in the biotechnological industry due to its high capacity for protein production. Although many proteins have been expressed efficiently using the optimized xylose inducible system so far, there is a considerable demand for novel promoters with varying activities, particularly ...

Messenger RNA and polyribosomes in Bacillus megaterium

Journal of Molecular Biology, 1965
A technique has been developed whereby growing cultures of Bacillus megaterium can be harvested rapidly and disrupted by gentle means. Cultures were pulse-labeled with tritiated uridine and lysates were subjected to sucrose density-gradient centrifugation.
