Genome sequence of Lentisphaera araneosa HTCC2155T, the type species of the order Lentisphaerales in the phylum Lentisphaerae.

Information on the genome content of deeply branching phyla with very few cultured members is invaluable for expanding understanding of microbial evolution. Lentisphaera araneosa HTCC2155(T) was isolated from the Oregon coast using dilution-to-extinction culturing. It is a marine heterotroph found in surface and mesopelagic waters in both the Pacific and Atlantic oceans and has the unusual property of producing a net-like matrix of secreted exopolysaccharide. Here we present the genome sequence of L. araneosa HTCC2155(T), importantly, one of only two sequenced members of the phylum Lentisphaerae.
