Query: NC_018704:81733 Amphibacillus xylanus NBRC 15112, complete genome
Lineage: Amphibacillus xylanus; Amphibacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Amphibacillus xylanus is an alkaliphilic microorganism that grows at pH 8 - 10. This organism is also able to digest xylan aerobically and anaerobically. Facultative anaerobic, spore-forming, Gram-positive bacterium isolated from alcaline compost of manure with grass and rice straw.
Subject: NC_008044:136844 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.
