lentisphaera araneosa lentisphaera araneosa lentisphera araneosa is a marine bacteria strain in the bacterial phylum lentisphaerota. they are able to produce viscous transparent exopolymers and grow attached to each other by the polymer in a three-dimensional configuration. they are part of the natural surface bacterial population in the atlantic and pacific oceans. they are less than 1% of the total bacterial community. this species is gram negative, non-motile, non-pigmented, aerobic, chemoheterotrophic, and facultatively oligotrophic sphere-shaped. its genome has been sequenced. lentisphaerae aranesa scientific classification domain: bacteria phylum: lentisphaerota class: lentisphaeria order: lentisphaerales family: lentisphaeraceae genus: lentisphaeracho et al. 2004 species: l. araneosa binomial name lentisphera araneosacho et al. 2004
