Verrucomicrobia

Verrucomicrobium
Prosthecobacter Verrucomicrobia is a recently described phylum of bacteria. This phylum contains only a few described species (Verrucomicrobia spinosum , is an example, the phylum is named after this). The species identified have been isolated from fresh water and soil environments. A number of as-yet uncultivated species have been identified in association with eukaryotic hosts including extrusive explosive ectosymbionts of protists and endosymbionts of nematodes residing in their gametes.

Evidence suggests that verrucomicrobia are abundant within the environment, and important (especially to soil cultures). This phylum is considered to have two sister phyla Chlamydiae and Lentisphaera.
