Germination of Spores of Rusts

Germination of single bacterial spores.

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. The curves revealed that the germination process in single spores had two distinct phases; an initial rapid phase was followed by a second slower phase. Under the experimental condition employed, ...

Kinetics of Germination of Bacillus Spores.

Vary, J. C. (University of Wisconsin, Madison), and H. O. Halvorson. Kinetics or germination of Bacillus spores. J. Bacteriol. 89:1340-1347. 1965.-The kinetics of germination of Bacillus cereus strain T spores was accurately described by McCormick. To study the mechanism of germination, it is necessary to correlate the characteristic changes in a population of germinating spores with the behavi...

Germination requirements of Bacillus macerans spores.

2-Phenylacetamide is an effective germinant for spores of five strains of Bacillus macerans, particularly in the presence of fructose. Benzyl penicillin, the phenyl acetamide derivative of penicillin, and phenylacetic acid are also good germinants. l-Asparagine is an excellent germinant for four strains. alpha-Amino-butyric acid is moderately effective. Pyridoxine, pyridoxal, adenine, and 2,6-d...

Calcium Release and Germination of Bacterial Spores

During germination and subsequent outgrowth of bacterial spores a number of well documented physical and biochemical changes occur (Gould & Dring, 1972). A wide variety of chemical and physical stimuli will initiate these changes, including potential metabolites such as amino acids, sugars and purine ribosides, non-nutrients such as EDTA and surfactants and physical treatments such as hydrostat...
