Query: NC_015844:3524175 Zobellia galactanivorans, complete genome
Lineage: Zobellia galactanivorans; Zobellia; Flavobacteriaceae; Flavobacteriales; Bacteroidetes; Bacteria
General Information: Zobellia galactanivorans is a marine bacterium that participates in the carbon cycle as a decomposer of dead algae. This organism produces several potentially commercially important polysaccharidases which are able to degrade agar and carageenan.
Subject: NC_006177:280234 Symbiobacterium thermophilum IAM 14863, complete genome
Lineage: Symbiobacterium thermophilum; Symbiobacterium; Shewanellaceae; Clostridiales; Firmicutes; Bacteria
General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
