Autolysis of Escherichia coli.
Autolysis of unwashed exponential-phase Escherichia coli cells was efficiently promoted by first submitting them to a quick downshock with distilled water before an upshock with 0.5 M sodium acetate, pH 6.5. The association of these two osmotic shocks had a remarkable synergistic effect and led to significant decreases in turbidity and viability. Different factors influencing the rate of cell l...
متن کاملStudies of Autolysis
In 1904 Lane-Claypon and Schryverl reported a latent period in autolysis amounting in the normal liver to about 4 hours. In the livers of fasting animals the latent period was absent or much shorter than in the well fed. If active trypsin preparations were introduced into the autolyzing liver mass, digestion began at once. These observations led the authors to the conclusion that in the living ...
متن کاملA Study of Pneumococcus Autolysis
1. Autolysis of Pneumococcus is accompanied by proteolysis, which results in an increase in amino and non-coagulable nitrogen. 2. Autolysis of Pneumococcus is accompanied by lipolysis during which there is a liberation of ether-soluble fatty acids. 3. When extracts containing the active intracellular enzymes are added to heat-killed pneumococci, lysis of the cells occurs and there is an increas...
متن کاملPlant hairy root cultures as plasmodium modulators of the slime mold emergent computing substrate Physarum polycephalum
Roots of the medicinal plant Valeriana officinalis are well-studied for their various biological activities. We applied genetically transformed V. officinalis root biomass to exert control of Physarum polycephalum, an amoeba-based emergent computing substrate. The plasmodial stage of the P. polycephalum life cycle constitutes a single, multinucleate cell visible by unaided eye. The plasmodium m...
متن کاملAutolysis in strains of viridans streptococci.
Seven strains of viridans streptococci of the species Streptococcus sanguis, S. mutans and S. mitis were investigated for autolysis. The effect of pH, salt concentration and temperature on the autolytic process was studied in Na2HPO4/NaH2PO4 buffer. Whole cells and walls of all strains autolysed most rapidly at pH values above 7. Autolysis of whole cells of S. sanguis and one strain of S. mitis...
