Infrared absorption spectrum of carbon disulfide.
The infrared absorption spectrum of carbon disulfide has been remeasured in the region from 2 to 24 I' with cells up to 5 mm in t hickness. Fifteen bands were observed , some however being of low intensity. The strongest band for the liquid occurs at 6.621' , and t he second harmonic of this band was observed at 2.22 1' , but t he first harm onic, which should be at about 3.33 1' , was not obse...
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 کاملInfrared absorption spectrum of the simplest Criegee intermediate CH2OO.
The Criegee intermediates are carbonyl oxides postulated to play key roles in the reactions of ozone with unsaturated hydrocarbons; these reactions constitute an important mechanism for the removal of unsaturated hydrocarbons and for the production of OH in the atmosphere. Here, we report the transient infrared (IR) absorption spectrum of the simplest Criegee intermediate CH2OO, produced from C...
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...
