Toward an ecological classification of soil bacteria.
Ecology, 2007Although researchers have begun cataloging the incredible diversity of bacteria found in soil, we are largely unable to interpret this information in an ecological context, including which groups of bacteria are most abundant in different soils and why ...

Annual Review of Microbiology, 2001
Quorum sensing is the regulation of gene expression in response to fluctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell ...

Quorum sensing: cell-to-cell communication in bacteria.
Annual Review of Cell and Developmental Biology, 2005Bacteria communicate with one another using chemical signal molecules. As in higher organisms, the information supplied by these molecules is critical for synchronizing the activities of large groups of cells. In bacteria, chemical communication involves

Preventing Bacteria‐Induced Disease With Bacteria
Nutrition in Clinical Practice, 2012Oral administration of a probiotic preparation was shown to be effective in preventing the recurrence of chronic pouchitis in a classic double‐blind, placebo‐controlled trial. This was a novel and unique approach to the care of these patients. Dysbiosis, a condition of microbial imbalance, has been implicated in the pathogenesis of inflammatory bowel ...

The Botanical Review, 1938
The structure of the bacterial cell has been the subject of numerous investigations since the early years of bacteriology. Up to a quarter of a century ago a considerable literature accumulated, as it is easy to see from the last extensive review, "Die Zelle der Bakterien,"' published by A. Meyer in 1912.

Science, 1966 Motile Escherichia coli placed at one end of a capillary tube containing an energy source and oxygen migrate out into the tube in one or two bands, which are clearly visible to the naked eye and can also be demonstrated by photography, microscopy, and densitometry and by assaying for bacteria throughout the tube ...

Science, 1975
Bacteria with motility directed by the local geomagnetic field have been observed in marine sediments. These magnetotactic microorganisms possess flagella and contain novel structured particles, rich in iron, within intracytoplasmic membrane vesicles. Conceivably these particles impart to cells a magnetic moment.

Mineralization of Bacteria [PDF]
Science, 1962 A variety of viable and nonviable bacteria became mineralized with hydroxyapatite when implanted in dialysis bags in the peritoneal cavities of rats. The microscopic pattern of mineral deposition appeared analogous to that in the formation of oral calculus. Since nonviable organisms were mineralized at an accelerated rate, bacterial metabolic processes

msDNAs are small, structurally unique satellite DNAs found in a number of Gram-negative bacteria. Composed of hundreds of copies of single-stranded DNA--hence the name multicopy single-stranded DNA--msDNA is actually a complex of DNA, RNA, and probably protein. These peculiar molecules are synthesized by a reverse transcription mechanism catalyzed by a

The enhancement of plant growth by free-living bacteria
, 1995The ways in which plant growth promoting rhizobacteria facilitate the growth of plants are considered and discussed. Both indirect and direct mechanisms of plant growth promotion are dealt with.
