Fibrobacterota бактериялар тобының сипаттамасы

Phylum of bacteria

Fibrobacterota is a small bacterial phylum which includes many of the major rumen bacteria, allowing for the degradation of plant based cellulose in ruminant animals. Members of this phylum were categorized in other phyla. The genus Fibrobacter (the only genus of Fibrobacterota) was removed from the genus Bacteroides in 1988.

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LSPN) and the National Center for Biotechnology Information (NCBI). Class Chitinispirillia Sorokin et al. 2016

The phylum Fibrobacterota is considered to be closely related to the CFB [Cytophaga Flavibacterium Bacteroidota]. The two described species in this genus namely, Fibrobacter succinogenes and Fibrobacter intestinalis are important members of fibrolytic communities in mammalian guts and have received a lot of attention in recent decades due to the long standing interest microbes capable of degrading plant fiber. Molecular evidence based on the amplification of 16rRNA genes from various environments suggest that the phylum is much more widespread than previously thought. Most of the clones from mammalian environments group along with the known isolates in what has been called subphylum 1. and in some litter feeding cockroaches. The predominance of subphylum 2 in cellulolytic fibre associated bacterial communities in hindguts of wood feeding Nasutitermes corniger suggests that they play an important role in the breakdown of plant material in higher termites.
