Permeability of dormant spores of Bacillus subtilis to gramicidin S.
Gramicidin S, dissolved in ethanol, penetrated into the inside of the dormant spores of Bacillus subtilis, had a partial inhibitory effect on L-alanine-initiated germination and completely inhibited their outgrowth and vegetative growth. The activity of particulate NADH oxidase of the antibiotic-treated dormant spores was also influenced significantly. Abnormal morphological changes were observ...
متن کاملWater and Small-Molecule Permeation of Dormant Bacillus subtilis Spores.
UNLABELLED We use a suspended microchannel resonator to characterize the water and small-molecule permeability of Bacillus subtilis spores based on spores' buoyant mass in different solutions. Consistent with previous results, we found that the spore coat is not a significant barrier to small molecules, and the extent to which small molecules may enter the spore is size dependent. We have devel...
متن کاملRibonucleic Acids of Bacillus Subtilis Spores and Sporulating Cells.
Doi, Roy H. (Syracuse University, Syracuse N.Y.), and Richard T. Igarashi. Ribonucleic acids of Bacillus subtilus spores and sporulating cells. J. Bacteriol. 87:323-328. 1964.-The ribonucleic acids (RNA) of Bacillus subtilis spores were analyzed for their size and base composition. Soluble and ribosomal RNA identical to those found in vegetative cells were present in spores. A base ratio differ...
متن کاملThe stability of messenger ribonucleic acid during sporulation in Bacillus subtilis.
The stability of postlogarithmic mRNA has been assessed in Bacillus subtilis during sporulation time periods. The appearance of refractile bodies, alkaline phosphatase synthesis, and total protein synthesis is controlled by mRNA which has an estimated half-life of less than 10 min. Inhibition of RNA synthesis at various times by rifampin addition or temperature shift with a temperature-sensitiv...
متن کاملLevels of germination proteins in dormant and superdormant spores of Bacillus subtilis.
Bacillus subtilis spores that germinated poorly with saturating levels of nutrient germinants, termed superdormant spores, were separated from the great majority of dormant spore populations that germinated more rapidly. These purified superdormant spores (1.5 to 3% of spore populations) germinated extremely poorly with the germinants used to isolate them but better with germinants targeting ge...
