Dormancy in non - sporulating bacteria
"All stood amazed, until an old woman, tottering out from among the crowd, put her hand to her brow, and peering under it in his face for a moment exclaimed , 'Sure enough! it is Rip Van Winkle-it is himself. Welcome home again, old neighbour-Why, where have you been these twenty long years?"' lrving, W. An analogical "field" construct in cellular biophysics: history and present status. "These ...
متن کاملThe Ger receptor family from sporulating bacteria.
Bacterial spores are specialized cells that are exceptionally resistant to environmental stress. Spores convert back to actively growing cells, a process called germination, upon nutrient detection. The most common, initial step in the germination process is the recognition of small molecule germinants by germination (Ger) receptors. Ger receptors are inner-membrane heterocomplexes formed by th...
متن کاملThe Production of Bactericidal Substances by Aerobic Sporulating Bacilli
Several species of aerobic sporulating bacilli recently isolated from soil, sewage, manure, and cheese, as well as authentic strains obtained from type culture collections, have been found to exhibit antagonistic activity against unrelated microorganisms. Cultures of these aerobic sporulating bacilli yield an alcohol-soluble, water-insoluble fraction,-tyrothricin,-which is bactericidal for most...
متن کاملNon-Sporulating Anaerobic Bacteria of the Intestinal Tract : I. Occurrence and Taxonomic Relationships.
This investigation was undertaken mainly to extend the observations of Eggerth and Gagnon (1933) and Weiss and Rettger (1937) on the occurrence of non-spore-forming, obligately anaerobic rod-shaped bacteria in the human intestine. Paths soon led to a study of relationships of the various organisms to each other, and of the gram-negative types to certain other closely related bacteria. A volumin...
متن کاملAerobic anoxygenic phototrophic bacteria.
The aerobic anoxygenic phototrophic bacteria are a relatively recently discovered bacterial group. Although taxonomically and phylogenetically heterogeneous, these bacteria share the following distinguishing features: the presence of bacteriochlorophyll a incorporated into reaction center and light-harvesting complexes, low levels of the photosynthetic unit in cells, an abundance of carotenoids...
