Correlation between the bacterioclastic action of a bis-quaternary ammonium compound and outer membrane proteins.
Bis-quaternary ammonium compounds (bis-QACs) have the ability to cause a rapid and abundant leakage of the turbid materials from cells, and such a bacterioclastic ability leads to a potent bactericidal activity. In order to clarify the detailed mechanism of the bactericidal action of bis-QACs, the correlation between the bacterioclastic action of 4,4'-(1,6-hexamethylenedithio)bis(1-octylpyridin...
متن کاملSporicidal characteristics of heated dolomite powder against Bacillus subtilis spores.
Dolomite is a double salt composed of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3). The heat treatment of CaCO3 and MgCO3 respectively generates calcium oxide (CaO) and magnesium oxide (MgO), which have antimicrobial activity. In this study, heated dolomite powder (HDP) slurry was investigated for its sporicidal activity against Bacillus subtilis ATCC 6633 spores. The B. subtilis s...
متن کاملAction of disinfectant quaternary ammonium compounds against Staphylococcus aureus.
Mode-of-action studies concluded that alkyldimethylbenzylammonium chloride (ADBAC) (a blend of C(12), C(14) and C(16) alkyl homologues) and didecyldimethylammonium chloride (DDAC) are both membrane-active agents, possessing subtly different modes of action reflecting early cell interactions against Staphylococcus aureus. ADBAC and DDAC exhibited similar MIC behaviors from 0.4 ppm to 1.8 ppm ove...
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 کاملUltracytochemical localization of ATP-hydrolysing activity in vegetative cells, spores and isolated cytoplasmic membranes of Bacillus subtilis 168.
The localization of ATP-hydrolysing activity in vegetative cells, spores and isolated membranes of Bacillus subtilis 168 was studied by a cytochemical method combined with electron microscopy. The activity was located mainly in the cytoplasmic membrane and the mesosomes, and was also found in the inner layer of the cell wall facing the cytoplasmic membrane. Activity was also detected in the cro...
