Ultrastructural analysis during germination and outgrowth of Bacillus subtilis spores.
Electron microscopy of thin sections of dormant and germinating spores of Bacillus subtilis 168 revealed a progressive change in the structure of the cortex, outer spore coat, and inner spore coat. The initial changes were observed in the cortex region, which showed a loose fibrous network within 10 min of germination, and in the outer spore coat, which began to be sloughed off. The permeabilit...
متن کاملChromosomes in Bacillus subtilis spores and their segregation during germination.
Spores of a thymine-requiring mutant of Bacillus subtilis 168 leucine(-), indole(-), thymine(-)) were uniformly labeled with (3)H-thymidine. These were seeded on thinlayer agar plates where they germinated into long-chained microcolonies. Autoradiograms were used to measure the distribution of labeled deoxyribonucleic acid in the chains of cells, which ranged in length from 2 to 32 cells. Four ...
متن کاملHtrC is involved in proteolysis of YpeB during germination of Bacillus anthracis and Bacillus subtilis spores.
Bacterial endospores can remain dormant for decades yet can respond to nutrients, germinate, and resume growth within minutes. An essential step in the germination process is degradation of the spore cortex peptidoglycan wall, and the SleB protein in Bacillus species plays a key role in this process. Stable incorporation of SleB into the spore requires the YpeB protein, and some evidence sugges...
متن کاملRole of GerD in germination of Bacillus subtilis spores.
Spores of a Bacillus subtilis strain with a gerD deletion mutation (Delta gerD) responded much slower than wild-type spores to nutrient germinants, although they did ultimately germinate, outgrow, and form colonies. Spores lacking GerD and nutrient germinant receptors also germinated slowly with nutrients, as did Delta gerD spores in which nutrient receptors were overexpressed. The germination ...
