Spheroidal forms of Bacillus megaterium induced by potassium tellurite.
This communication is concerned with the formation of spheroidal bodies from Bacillus megaterium strain KM, by the action of potassium tellurite in a hypertonic sucrose medium. Cells grown in sucrose-casein hydrolyzate broth (Lederberg and St. Clair, J. Bacteriol., 75, 143, 1958) were inoculated into fresh broth and aerated at 37 C for 3 to 4 hr. Potassium tellurite (final concentration 0.05 pe...
متن کاملPlasmolysis in Bacillus Megaterium.
Weibull, Claes (Central Bacteriological Laboratory of Stockholm City, Stockholm, Sweden). Plasmolysis in Bacillus megaterium. J. Bacteriol. 89:1151-1154. 1965.-Sucrose solutions stronger than 1 m caused plasmolysis in Bacillus megaterium strain M, whereas concentrated NaCl and KNO(3) solutions were ineffective. In plasmolyzed cells, mesosome bodies were found in pockets between the cytoplasmic ...
متن کاملMegacinogenic plasmids of Bacillus megaterium.
Megacins A-216 and A-19213 in Bacillus megaterium are plasmid encoded, as shown by analysis of cured, non-megacinogenic (Meg-) derivatives of strains 216 and ATCC 19213 and by polyethylene glycol-mediated protoplast transformation of Meg- bacteria with plasmid DNA. The results of both techniques implicated a 31-megadalton plasmid, pBM309, in megacin A-216 production and a 29-megadalton plasmid,...
متن کاملEnzyme localization in Bacillus megaterium.
Weibull (1953a) has shown that after osmotic lysis of protoplasts of Bacillus megaterium, prepared by controlled treatment with lysozyme, only two microscopically detectable structures remain; membrane-like bodies termed "ghosts," and granules. The ghosts were found to sediment as a dark yellow fraction by centrifugation at 10,000 G (Weibull, 1953b) and to contain almost all the pigmented mater...
متن کاملComplete Genome of Bacillus megaterium Podophage Pookie
Bacteriophage Pookie is a novel podophage, isolated from soil, which infects Bacillus megaterium. B. megaterium is an important host for large-scale recombinant protein production. Here, we present the complete genome of phage Pookie and describe its core features.
