Diversity of Bacterial Chemosensory Arrays
Trends in Microbiology, 2020Chemotaxis is crucial for the survival of bacteria, and the signaling systems associated with it exhibit a high level of evolutionary conservation. The architecture of the chemosensory array and the signal transduction mechanisms have been extensively studied in Escherichia coli.

The glycerophospholipids phosphatidylethanolamine, phosphatidylglycerol (PG), and cardiolipin (CL) are major structural components of bacterial membranes. In some bacteria, phosphatidylcholine or phosphatidylinositol and its derivatives form part of the membrane.

Tryptophanase in Diverse Bacterial Species
Journal of Bacteriology, 1969The distribution of tryptophanase was studied. The highest observed specific activity, μmoles per minute per milligram (dry weight) cells, is given in parentheses after each species. Tryptophanase was inducible and repressible in Escherichia coli (.914), Paracolobactrum coliforme (.210),

Unravelling the bacterial diversity in the atmosphere
Applied Microbiology and Biotechnology, 2013The study of airborne biological particles ('bioaerosols') has gained interest in recent years, due to an increasing amount of evidence suggesting that this fraction of airborne particulate matter may play a critical role in the negative effects of aerosols on biological systems.

Bacterial diversity in aphthous ulcers
Oral Microbiology and Immunology, 2007Introduction: Recurrent aphthous ulcers are common lesions of the oral mucosa of which the etiology is unknown. This study aimed to estimate the bacterial diversity in the lesions and in control mucosa in pooled samples using a culture‐independent molecular approach.Methods: Samples were collected from ten healthy individuals and ten individuals with

Determination of Bacterial Diversity of Propolis Microbiota
Chemistry & Biodiversity, 2023AbstractPropolis is a natural resinous mixture produced by the excretions of honeybees. PCR amplification of the 16S rRNA gene region was achieved using DNA of pre‐enriched propolis samples collected from Apis mellifera production hives (n=37) in Eastern Türkiye (Bingöl and its regions). Next‐generation sequencing and metabarcoding techniques were used

Bacterial Diversity in the Human Gut
2004Publisher Summary The human digestive tract is colonized by highly complex microbial ecosystem containing vast numbers of bacteria that could be assigned to several hundred bacterial species. Bacterial colonization of the gut is affected by a wide variety of host, microbiological, environmental and dietary factors, as indicated in the chapter.

Bacterial Diversity at High Temperature
1976An increasing number of organisms which are able to grow at high temperature has been isolated during the last few years.Our purpose in this paper is to analyze their properties from a microbiological point of view. The discussion will only deal with thermophilic procaryotes to the exclusion of blue-green algae (Castenholz, 1969) and actinomycetes ...

Bacterial diversity in an industrial wastewater bioreactor
Applied Microbiology and Biotechnology, 2003Industrial wastewater bioreactors are potentially important sources of novel biocatalysts. However, the microbial populations in these bioreactors are not well characterized. The microbial community in an industrial wastewater bioreactor was surveyed by extracting DNA from a sample of activated sludge, followed by PCR amplification and sequencing of ...

Bacterial diversity in agroecosystems
Agriculture, Ecosystems & Environment, 1999All life forms rely on bacterial processes for their survival. Bacterial diversity is greater than the diversity of any other group of organisms. Bacteria are responsible for diverse metabolic functions that affect soil and plant health. Nutrient cycling, organic matter formation and decomposition, soil structure formation, and plant growth promotion ...
