Initiation of Bacterial Spore Germination [PDF]
Journal of Bacteriology, 1968 To investigate the problem of initiation in bacterial spore germination, we isolated, from extracts of dormant spores of Bacillus cereus strain T and B. licheniformis , a protein that initiated spore germination when added to a suspension of heat-activated spores.

A Simplified Bacterial Spore Stain
Stain Technology, 1950A simplification of the Schaeffer-Fulton spore stain for bacteria is presented. It is shown that omission of the heating step during staining with malachite green resulted in spore stains as good as when the heat was applied. The simplified procedure involves (1) heat fixation of the smear by 20 passages through the flame, (2) staining with saturated ...

Germination of Single Bacterial Spores [PDF]
Journal of Bacteriology, 1969 Changes in refractility and optical density occurring in individual spores of Bacillus cereus T and B. megaterium QM B1551 during germination were investigated by use of a Zeiss microscope photometer.

Biosynthesis of bacterial spore coats
Journal of Molecular Biology, 1968Abstract The biochemical events associated with the assembly of bacterial spore coat proteins have been studied. Pulse-chase experiments using a variety of labeled amino acids have shown that coat precursor protein synthesis begins at the cessation of growth when sporulation commences (early forespore), but several hours prior to the appearance of ...

The Regional Radiosensitivity of Bacterial Spores
Radiation Research, 1970Ionizing radiation can induce bacterial spores to undergo changes associated with germination. By using low-energy electrons it was possible to separate two regions of the spore radiosensitive with respect to loss of optical density. These two regions coincide with two regions radiosensitive with respect to loss of viability. The region deep within the

Splitting Line of Bacterial Spore
Nature, 1967THE mechanisms involved in the germination of bacterial spores have been studied extensively from the biochemical and morphological points of view11,2. Details of morphological changes occurring during germination, however, have not yet been demonstrated clearly, It is not known whether or not, when a new vegetative cell emerges from the spore, the ...

The kinetics of germination in bacterial spores
Journal of Theoretical Biology, 1982Abstract The entire absorbance vs. time curve of a sample of germinating bacterial spores can be accurately described by a model which considers that the spores rate of entry into the phase initiation of germination is determined by transitions between three spore states.

Molecular Structure of the Bacterial Spore
1978Publisher Summary In the differentiation of a bacterial cell into a spore, a number of new morphological structures are formed. The cortex and germ cell wall are specialized adaptations of vegetative structures. Spore coats, exosporia, and appendages are new structures embodying new classes of microbial products. Within the spore cell or core, unique
