, GN02 and TM6were not consistently present in all samples.
In contrast to the gut and the GFPs, the feed was dominated by the phyla Firmicutes (48%) and Proteobacteria (42%); and the waterway by Chloroflexi
(29%) and Proteobacteria (49%).
The most abundant of these microbes are members of the Chloroflexi
, Clostridia, and candidate division OD1, followed by some Euryarchaeota.
Members of the following phyla were detected in nearly all of the samples: Actinobacteria, Bacteroidetes, Chloroflexi, Cyanobacteria, Firmicutes, and Proteobacteria (Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria, and Gammaproteobacteria).

The researchers said that the new charts suggest that 6,157 out of 9,740 prokaryotic species - including cyanobacteria, actinobacteria, bacilli and chloroflexi
- share a common ancestor that was adapted to life on land.
05) were observed in the percentages of Actinobacteria, Chloroflexi
, Cyanobacteria, Elusimicrobia, Lentisphaerae, Spirochaetes, Tenericutes, unclassified Bacteria, and Verrucomicrobia between the control and the acarbose group.
As displayed in Table 1, sequence analysis (about 650 bp) revealed the presence of 27 genera of bacteria belonging to 12 bacterial groups (the [alpha], [beta], [gamma], and [delta] classes of Proteobacteria and the Acidobacteria, Actinobacteria, Bacteroidetes, Chloroflexi
, Cyanobacteria, Firmicutes, Planctomycetes, Verrucomicrobia phyla of bacteria) present in mussel homogenates.
The remaining 57% separated into the following phyla: planctomycetales (12%), actinobacteria (9%), gemmatimonadetes (9%), firmicutes (5%), chloroflexi (5%), acidobacteria (4%), and 13% of unknown bacterial origin.
The Spanish cave samples were taken from cave paintings and the surrounding rock surfaces and consisted of proteobacteria (41%)), acidobacteria (16%), actinobacteria (20%), firmicutes (11%), cytophaga/flexibacter/bacteroides (6%), nitrospira (4%), chloroflexi (1%), and candidate WS3 division (1%).
Remaining sequences separated into the following phyla: planctomycetales (12%), actinobacteria (9%), gemmatimonadetes (9%), firmicutes (5%), chloroflexi (5%), and acidobacteria (4%).
The ability to use chloroethenes as energy-yielding electron acceptors is distributed among several bacterial groups, including different subdivisions of the proteobacteria, the gram-positive bacteria, and the Chloroflexi
(formerly green nonsulfur bacteria).
