Betaproteobacteria are a class of Gram-negative bacteria, and one of the eight classes of the phylum Pseudomonadota (synonym Proteobacteria). (wikipedia.org)
Bacteria4
The Betaproteobacteria are a class comprising over 75 genera and 400 species of bacteria. (wikipedia.org)
In times long past, highly evolved eukaryotes, for example biochemists, oc-ca-sio-nal-ly quipped that bacteria were nothing more than a bag of en-zymes. (asmblog.org)
The endophytic microbial diversity was also analyzed by PCR-DGGE using 16S rRNA-based universal and group-specific primers for total bacteria, Alphaproteobacteria, Betaproteobacteria and Actinobacteria and 18S rRNA-based primers for fungi. (biomedcentral.com)
PCR-DGGE profile analysis and principal component analysis showed that the total bacteria, Alphaproteobacteria, Betaproteobacteria and fungi were influenced not only by the location within the plant (leaf vs. stem) but also by the presence of the main components of the L. sidoides essential oil (thymol and/or carvacrol) in the leaves.

Burkholderiales2
Four orders of Betaproteobacteria are currently recognised - the Burkholderiales, the Neisseriales, the Nitrosomonadales and the Rhodocyclales. (wikipedia.org)
The four orders of the Betaproteobacteria are sub-divided into families: Burkholderiales (type order) comprises the families Burkholderiacae (type family), Alcaliginaceae, Comamonadaceae, Oxalobacteraceae and Sutterellaceae. (wikipedia.org)
Gammaproteobacteria2
[ 6 ] [ 9 ] Análises filoxenéticas e indeis conservados en gran cantidade doutras proteínas fornecen evidencias de que as Alphaproteobacteria se ramificaron antes ca moitos outros filos e clases de bacterias, agás as Betaproteobacteria e Gammaproteobacteria . (wikipedia.org)
Sulfur oxidizers from both Gammaproteobacteria and Betaproteobacteria were detected in 16S rRNA, soxB and RuBisCO gene libraries. (usf.edu)
Genus2
Some members of the Betaproteobacteria can cause disease in various eukaryotic organisms, including in humans, such as members of the genus Neisseria: N. gonorrhoeae and N. meningitidis being primary examples, which cause gonorrhea and meningitis respectively, as well as Bordetella pertussis which causes whooping cough. (wikipedia.org)
Almost all Lumbricid earthworms (Oligochaeta: Lumbricidae) harbor extracellular species-specific bacterial symbionts of the genus Verminephrobacter ( Betaproteobacteria ) in their nephridia. (frontiersin.org)
Organisms1
Together, the Betaproteobacteria represent a broad variety of metabolic strategies and occupy diverse environments from obligate pathogens living within host organisms to oligotrophic groundwater ecosystems. (wikipedia.org)
Soils1
A number of Betaproteobacteria are diazotrophs, meaning that they can fix molecular nitrogen from the air as their nitrogen source for growth - this is important to the farming industry as it is a primary means of ammonium levels in soils rising without the presence of leguminous plants. (wikipedia.org)
Class1
Betaproteobacteria are a class that has a gram-negative structure and is involved in nitrogen fixation, which plays an important role in many plants. (paulsec.com)
Gamma1
We just lately demonstrated that the Escherichia coli ribosome is strong sufficient to accommodate international 16S rRNAs from numerous gamma- and betaproteobacteria micro organism (Kitahara et al. (redasoft.com)
Sequences1
A significant number of sequences associated with known methylotrophs from the Betaproteobacteria were obtained, including Methylotenera, Methylophilus and Methylovorus, supporting the view that cycling of one-carbon compounds may be an important process within Movile Cave. (usf.edu)
Members3
Whilst most members of the Betaproteobacteria are heterotrophic, deriving both their carbon and electrons from organocarbon sources, some are photoheterotrophic, deriving energy from light and carbon from organocarbon sources. (wikipedia.org)
Other economically important members of the Betaproteobacteria are able to use nitrate as their terminal electron acceptor and can be used industrially to remove nitrate from wastewater by denitrification. (wikipedia.org)

Alphaproteobacteria1
The remaining Gram-negative belonged the Alphaproteobacteria, Betaproteobacteria, Flavobacteria and Sphingobacteria classes. (auburn.edu)

Present2
We present the complete genomic sequence of the essential symbiont Polynucleobacter necessarius (Betaproteobacteria), which is a valuable case study for several reasons. (doe.gov)
Betaproteobacteria genes were identified to be present in the propionate pathway, which becomes enhanced in high-quality forage-based diets, indicating a syntrophic relationship may be occurring to reduce methane emissions in beef cattle. (unl.edu)
Important2
Betaproteobacteria are economically important, with roles in maintaining soil pH and in elementary cycling. (wikipedia.org)
