THE COMPOSITION AND STRUCTURE OF BACTERIAL SPORES [PDF]

Journal of Cell Biology, 1963
The composition of the insoluble "integuments" and soluble "contents" fractions of spores of four Bacillus species of widely differing heat resistance were compared. Electron microscopy of thin sections was also used to determine and compare the morphological structures in the integument preparations.

Germination of Single Bacterial Spores

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, 1968
Abstract 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 ...

Initiation of Bacterial Spore Germination

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, 1950
A 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 ...

Splitting Line of Bacterial Spore

Nature, 1967
THE 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 Regional Radiosensitivity of Bacterial Spores

Radiation Research, 1970
Ionizing 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

Molecular Structure of the Bacterial Spore

1978
Publisher 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
