chryseobacterium capnotolerans chryseobacterium capnotolerans 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 %. its name derives from greek kapnos (for “smoke”, used in biology for carbon dioxide) and latin tolerans (for “tolerating”). chryseobacterium capnotolerans scientific classification domain: bacteria phylum: bacteroidota class: flavobacteriia order: flavobacteriales family: flavobacteriaceae genus: chryseobacterium species: c. capnotolerans binomial name chryseobacterium capnotoleransheidler von heilborn et al. 2022 microbiologic characteristics the species is cytochrome c oxidase-positive and catalase-positive, like other species from the genus chryseobacterium. 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. another characteristic of the species is the presence of menaquinone 6 and the orange-colored pigment flexirubin, as described for the whole genus before. genetics the genome was fully-sequenced and uploaded at the ncbi database. it consists of 5.36 mega base pairs. the dna g+c content is 35.51 mol%.
