Overview

  • Phocaeicola salanitronis, (aka Bacteroides salanitronis), is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. The DNA G+C content is 46.9%. Phocaeicola salanitronis is probably a common, although minor, coloniser of the gut. (Lan2006)



  • This organism has been recovered from caeca of chickens and human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal.

  • NOTES

    Bacteroides salanitronis (strain DSM 18170 / JCM 13567 / BL78) is a strictly anaerobic, chemoorganotroph, non-spore-forming, non-motile Gram-negative bacterium isolated from the cecum of a healthy chicken. The cells are generally rod-shaped (0.4-0.7 x 0.8-5.6 um) with rounded ends and are usually arranged singly or in pairs. The temperature optimum is 37 degrees Celsius. B. salanitronis is able to ferment glucose, mannose, sucrose, maltose, arabinose, cellobiose, lactose, xylose and raffinose. It does not utilize trehalose, glycerol, mannitol, sorbitol or melezitose; rhamnose and salicin are fermented weakly. Growth is possible in the presence of bile. Major fermentation products from broth (1% peptone, 1% yeast extract, and 1% glucose each (w/v)) are acetic acid and succinic acid, whereas isovaleric acid is produced in small amounts. Although B. salanitronis is non-motile, five genes associated with motility having been found in the genome. Many Bacteroides species are common inhabitants of the intestine where they help to degrade complex molecules such as polysaccharides or transform steroids. They also play a role as beneficent protectors of the gut against pathogenic microorganisms. (Adapted from PMID 21677856 ). [UP000007486]
