Chromohalobacter beijerinckii is a motile, rod-like, salt-loving, Gram-negative soil bacterium, 0.4–0.6 μm by 1.8–2.5 μm.
The bacterium was isolated in 1935 by T. Hof from fermented salted beans preserved in brine.[1] Hof named it Pseudomonas beijerinckii and identified it as the organism responsible for the purple color of that food. The pigment was the calcium salt of tetrahydroxy-p-benzoquinone Ca2C6O6, derived from the beans' myo-inositol.[2][3][4] The bacterium thrives in media with salt (NaCl) concentrations ranging from 0.35% to 25%; the optimum growth occurs at 8 to 10% NaCl, pH 7.5, and 35 °C.[5][6]
Reclassification
[edit]In 2006, comparison of the DNAs of P. beijerinckii's DNA with that of other Chromohalobacter bacteria indicated that it definitely belonged to that genus, and in fact was virtually identical to a species of Chromohalobacter recently isolated from salted herring of the Baltic Sea. Therefore the name was changed to Chromohalobacter beijerinckii.[5] It is very similar but distinct from the species Chromohalobacter japonicus, isolated in 2007 from a Japanese salty food.[7]
