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.

Other abundant classes were Gammaproteobacteria, Spirochaetes, Methanobacteria, Erysipelotrichi, Coriobacteriia, Fibrobacteria, and Betaproteobacteria.
The Phylum Proteobacteria was primarily composed of the Classes Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria and Gammaproteobacteria (23 [+ or -]4%, 8.
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].

The phylum Proteobacteria presented 40% of Gammaproteobacteria species (100% of unclassified--three sequences) and 60% of Betaproteobacteria with 33.
Similarly, class Betaproteobacteria was highly enriched in diabetic compared to non-diabetic persons (P = 0.
showed that in addition to the decreased abundance of Firmicutes, the Betaproteobacteria levels were significantly increased in diabetic patients compared to non-diabetic controls and their abundance significantly correlated with their plasma glucose concentrations (r = 0.
