▪ Abstract Uncultured microorganisms comprise the majority of the planet's biological
diversity. Microorganisms represent two of the three domains of life and contain vast …

Analyses of genome sequences, by some approaches, suggest that the widespread
occurrence of horizontal gene transfers (HGTs) in prokaryotes disguises their evolutionary …

Fibrobacter succinogenes is an important member of the rumen microbial community that
converts plant biomass into nutrients usable by its host. This bacterium, which is also one of …

The set of conserved eukaryotic protein-coding genes includes distinct subsets one of which
appears to be most closely related to and, by inference, derived from archaea, whereas …

To understand bacterial phylogeny, it is essential that the following two critical issues be
resolved:(i) development of well-defined (molecular) criteria for identifying the main groups …

Fibrobacteres, Chlorobi, and Bacteroidetes (FCB group) comprise three main bacterial phyla
recognized on the basis of 16S rRNA trees. Presently, there are no distinctive biochemical or …

The genome and natural habitat of Chitinophaga pinensis suggest it has the ability to
degrade a wide variety of carbohydrate-based biomass. Complementing our earlier …

Phylogenetic treeing approaches for the classification of organisms have a number of
important limitations. The most significant of these drawbacks is that different groups/taxa …

Aconitase and isocitrate dehydrogenase (IDH) enzyme activities were detected in
anaerobically prepared cell extracts of the obligate anaerobe Bacteroides fragilis. The …

Abstract Background The Bacteroidetes and Chlorobi species constitute two main groups of
the Bacteria that are closely related in phylogenetic trees. The Bacteroidetes species are …
