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.

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.

Bacteriophage growth in protoplasts of Bacillus megaterium

Biochimica et Biophysica Acta, 1955
Abstract One-step growth experiments show that bacteriophage C can grow in protoplasts of B. megaterium KM if the cells are infected prior to treatment with lysozyme. The phage yield of infected protoplasts is smaller that that of intact cells, and a single burst experiment establishes that the burst size of individual protoplasts is small.

Temperature range variants of Bacillus megaterium

Archives of Microbiology, 1977
Facultatively 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.

A Copper Requirement for the Sporulation of Bacillus megaterium

Nature, 1962
AN important relationship exists between metal ions and bacterial sporulation1,2. In previous mineral studies with spore-formers c.p. or reagent grade chemicals were used, and although important metal associations with sporulation have been revealed the presence and effect of unsuspected trace amounts of metallic ions were not considered.

"Flickering" in Protoplasts of Bacillus megaterium

Science, 1963
"Flickering," which has been observed in the erythrocytes of many animals, has now been observed in the protoplasts of Bacillus megaterium .

Osmotic properties of protoplasts of Bacillus megaterium

Experimental Cell Research, 1955
Abstract The osmotic properties of bacterial protoplasts have been investigated. The protoplasts were obtained by treating Bacillus megaterium cells suspended into polyethylene glycol or sucrose solutions with lysozyme. The concentration of these substances and hence the osmotic pressure of the medium before the removal of the cell wall has little ...
