proteobacteria

(prō″tē-ō-băk-tē′rē-ă)
A diverse phylum of gram-negative bacteria, which includes many intestinal bacteria (e.g., Escherichia coli, Salmonella), the nitrogen-fixing bacteria, and the anaerobic purple bacteria.

Por su parte, la muestra de ADN genomico del aislado M1RLP amplificado con el ologonucleotidos F948 y R1492 sus secuencias mostro alta homologia con la secuencia de la bacteria Delftia tsuruhatensis, una Betaproteobacteria del orden Burkholderiales, con un 100% de identidad y cobertura mediante el analisis en Blast, al momento de hacer la reconstruccion filogenetica la secuencia obtenida presento pocos sitios informativos lo que impidio construir un arbol.
After 16 wk of grow-out, there was a consistent decrease in the proportion of Actinobacteria and Betaproteobacteria, compared with that found in the guts of weaning abalone, and an increase in the proportion of Mollicutes (Fig.
The OTUs were assigned to the classes Alphaproteobacteria (8 OTUs), Betaproteobacteria (2 OTUs) and Gammaproteobacteria (3 OTUs) (Table 2).
In total, six well-recognized classes (Gammaproteobacteria, Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria, Epsilonproteobacteria, and Zetaproteobacteria) were observed, among which Gammaproteobacteria (31.70-42.23%) in the R-samples and Alphaproteobacteria (22.13-25.40%) in the S-samples were the top two most abundant classes.
In general, the class level abundances of the 88 OTUs shared between the floodwaters from the vegetative and reproductive stages were very similar and were both dominated by Betaproteobacteria, Actinobacteria, and Alphaproteobacteria (Figures 4(a) and 4(b)).
PCR product (20 [micro]l) was loaded onto 8% (w/v) polyacrylamide gels, 1 mm thick, in 1x TAE buffer (20 mM Tris-acetate, 0.5 mM EDTA; pH9), with a 40-65% urea and formamide denaturant gradient for the study of Alphaproteobacteria, Betaproteobacteria, and Firmicutes, 45-75% for Actinobacteria, and 20-70% for the diazotrophic community.
Other abundant classes were Gammaproteobacteria, Spirochaetes, Methanobacteria, Erysipelotrichi, Coriobacteriia, Fibrobacteria, and Betaproteobacteria. However, differentially abundant bacterial communities were observed among the four breeds.
Ralstonia is classified under subphylum of betaproteobacteria. It has unique and enormous range of metabolic diversity.
In spite of the fact that the pioneer oildegrader bacteria are mostly Gammaproteobacteria, Betaproteobacteria and Actinobacteria, in present study we found a new member of Alphaproteobacteria which was able to use crude oil as the sole source of carbon [9].
