Non-involvement of Lysis during Sporulation of Bacillus Mycoides in Distilled Water
نویسندگان
چکیده
Washed vegetative cells of Bacillus mycoides obtained and treated under specified conditions have been found to sporulate when shaken in distilled water under specified conditions. Within limitations of the methods, a heat-resistant cell (spore) is produced for each heat-sensitive vegetative cell present initially. Several different experiments designed to detect massive lysis and cell growth during sporulation in distilled water yielded uniformly negative results. Evidence is furnished for the conclusion that a freshly formed spore (heat-resistant cell) weighs considerably less than its progenitor vegetative cell. The observed results are most satisfactorily explained as a direct conversion of a vegetative cell to a spore.

Non-involvement of Lysis during Sporulation of Bacillus Mycoides in Distilled Water* by Jerome
Powell and Hunter (1953) do not concur with the conclusions reached by this laboratory (Hardwick and Foster, 1952) that washed vegetative cells of aerobic bacilli can sporulate in the absence of exogenous nutrition and when growth is precluded. Their view is based essentially on the demonstration that under the conditions maintained in their experiments mass lysis of the cells initially present...
متن کاملSporulation in Distilled Water
Spores are formed when vegetative cells of sporing aerobes are shaken with distilled water at 37 degrees . These spores are derived from the small number of cells which survive lysis. The sporulation process involves increase and concentration of solid material in the cell, and is achieved at the expense of the products of lysis of 80 to 90 per cent of the resuspended cells.
متن کاملPolyhydroxybutyrate production in Bacillus mycoides DFC1 using response surface optimization for physico-chemical process parameters
The production of polyhydroxybutyrate (PHB) by Bacillus sp. is most often growth associated and is influenced by various physico-chemical parameters. Imbalanced nutrient conditions were often found to result in sporulation and low PHB production in Bacillus sp. In the present investigation, Bacillus mycoides DFC1 strain isolated from garden soil was studied for PHB production in glucose–peptone...
متن کاملStudies on an autolytic substance produced by an aerobic sporeforming bacterium.
The capacity of many "surface-active" materials to cause lysis of bacterial cultures is a well documented fact. In addition to lytic activity by nonbiologic detergents, one finds that many biologically produced substances have the ability to destroy the structural integrity of living microorganisms. Lysozyme lyses susceptible bacteria by hydrolyzing certain mucopolysaccharides necessary to the ...
متن کاملCell-wall lytic enzymes at sporulation and spore germination in Bacillus species.
When washed sporulating cells of Bacillus cereus were incubated in buffer a t 37" in the presence of toluene, a partial autolysis occurred resulting in the freeing of mature and immature spores. The autolysate contained lytic enzymes which attacked vegetative cells and cell-wall preparations, releasing hexosaminecontaining peptides of characteristic constitution. The most active enzyme preparat...
