Chryseobacterium capnotolerans is a Gram-negative, rod-shaped species of bacteria, which has been isolated primarily from pork sausage packed under CO2-enriched modified atmosphere. It is considered to be a potential food spoilage organism, which grows at elevated levels of CO2 of up to 40 %.[1] Its name derives from Greek kapnos (for “smoke”, used in biology for carbon dioxide) and Latin tolerans (for “tolerating”).
Microbiologic characteristics
The species is cytochrome c oxidase-positive and catalase-positive, like other species from the genus Chryseobacterium.[2] It grows on Tryptic soy agar at temperatures of 8 to 39 °C, tolerating NaCl concentrations of up to 4.5 %. Cells of Chryseobacterium capnotolerans are non-motile and 2 µm by 0.8 µm in dimension. The cell membrane of this species is characterized by the presence of phosphatidylethanolamine and various ornithine lipids. Additionally, the rare polar lipids sulfobacin A, flavolipin and cytolipin, as well as a glycolipid, were detected.[1] Another characteristic of the species is the presence of menaquinone 6 and the orange-colored pigment flexirubin, as described for the whole genus before.[2]
Genetics
The genome was fully-sequenced and uploaded at the NCBI database.[3] It consists of 5.36 mega base pairs. The DNA G+C content is 35.51 mol%.
