Query: NC_008048:2838769 Sphingopyxis alaskensis RB2256, complete genome
Lineage: Sphingopyxis alaskensis; Sphingopyxis; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Isolated from Resurrection Bay in the Gulf of Alaska. It is a model oligotrophic organism and forms a very small cell size. his genus was created from the Sphingomonas genus on the basis of phylogenetic, phenotypic, and chemotaxonomic characteristics. Sphingopyxis alaskensis is one of the most numerically abundant microbes found in oligotrophic marine waters and is an important contributor of biomass.
Subject: NC_015052:1569255 Bifidobacterium longum subsp. infantis 157F, complete genome
Lineage: Bifidobacterium longum; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria
General Information: This organism is found in adult humans and formula fed infants as a normal component of gut flora. Representatives of this genus naturally colonize the human gastrointestinal tract (GIT) and are important for establishing and maintaining homeostasis of the intestinal ecosystem to allow for normal digestion. Their presence has been associated with beneficial health effects, such as prevention of diarrhea, amelioration of lactose intolerance, or immunomodulation. The stabilizing effect on GIT microflora is attributed to the capacity of bifidobacteria to produce bacteriocins, which are bacteriostatic agents with a broad spectrum of action, and to their pH-reducing activity.
