Query: NC_014215:349917 Propionibacterium freudenreichii subsp. shermanii CIRM-BIA1,
Lineage: Propionibacterium freudenreichii; Propionibacterium; Propionibacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Propionibacterium freudenreichii is a member of the "dairy propionibacteria", commonly isolated from cheese and other dairy products. Propionibacterium freudenreichii subsp. shermanii, formerly Propionibacterium shermanii, is important for the development of flavor and the characteristic holes in Swiss cheese. In addition, Propionibacterium freudenreichii subsp. shermanii has been used as a probiotic for humans and animals and may have a role in preventing of colon cancer.
Subject: NC_008044:1401814 Silicibacter sp. TM1040, complete genome
Lineage: Ruegeria; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This strain was isolated from a culture of the dinoflagellate Pfiesteria piscicida CCMP1830 which has been implicated in many large scale algal blooms resulting in increased mortality in fish. The bacteria are attached to the surface of the dinoflagellate and in some ways allow the dinoflagellate to grow as those lacking the bacteria die off. The bacterium also chemotaxes towards the dinoflagellate product DMSP (dimethylsulfoniopropionate) and metabolizes it. DMSP is a major source of sulfur in marine ecosystems and plays a role in the sulfur biogeochemical cycle. The implication is a tight association between these important dinoflagellates and this marine bacterium.
