roseivirga echinicomitans roseivirga echinicomitans roseivirga echinicomitans is a species of gram-negative bacteria that belongs to the family flammeovirgaceae. it is a strictly aerobic, heterotrophic , pink-pigmented, non-motile bacterium from the genus roseivirga. it was first isolated from the sea urchin strongylocentrotus intermedius. roseivirga echinicomitans scientific classification domain: bacteria phylum: bacteroidota class: cytophagia order: cytophagales family: flammeovirgaceae genus: roseivirga species: r. echinicomitans binomial name roseivirga echinicomitansnedashkovskaya et al. 2005 type strain kctc 12370, kmm 6058, lmg 22587 r. echinicomitans is an aerobic bacterium that is capable of degrading a variety of organic compounds. its cells are long, slender, and have a filamentous shape. the bacteria produce pink-pigmented colonies on marine agar. the ecology and role of r. echinicomitans in marine environments is not well understood, but it has been suggested that it may play a role in the decomposition of organic matter in marine sediments. the genome of r. echinicomitans has been sequenced and analyzed, providing insights into the bacterium's metabolism and adaptation to its environment.
