Idiomarina
''Idiomarina'' is a genus of bacteria in the Gammaproteobacteria
Gammaproteobacteria is a class of bacteria in the phylum Pseudomonadota (synonym Proteobacteria). It contains about 250 genera, which makes it the most genera-rich taxon of the ...
. It is a rod shaped, gram-negative, aerobic cell with a single polar flagellum. The cells are typically 0.35 μm wide and 0.7–1.8 μm in length with optimum growth temperatures between 4–46 °C. It was isolated from a hydrothermal vent at 1,300m depth on the
Kamaʻehuakanaloa (formerly Loihi) submarine volcano, Hawaii.
Genome
The genome has been sequenced and contains 2,839,318 bp, with a GC content of 47.04%, encoding 2640 protein coding genes.
These include many enzymes involved in amino acid degradation and transport, leading to the hypothesis that these bacteria utilize protein particles present in their natural habitat. The genome also encodes enzymes for the synthesis of
exopolysaccharides
Extracellular polymeric substances (EPSs) are natural polymers of high molecular weight secreted by microorganisms into their environment. EPSs establish the functional and structural integrity of biofilms, and are considered the fundamental comp ...
that may be used in adherence to these particles.
