Marinomonas artica
Description and Significance
Marinomonas artica is a gram-negative, rod-shaped, and novel psychrotolerant bacteria that was first isolated from sea-ice just off the Canadian Basin of the Artic Ocean.
Psychrotolerant organisms like Marinomonas artica, are able to thrive in cold environments, degrading organic material and releasing necessary nutrients into the environment. They are also a great model organism to study to further our knowledge about psychrotolerant organisms, and just how they operate and survive in these harsh conditions.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
- 4.5 Mb - 1 chromosome
[still searching for info on]
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
- Marinomonas artica is a single rod-shaped cell with a flagella that makes it motile
-demonstrated an ability to utilize a comparatively wide range of carbon compounds as the sole source of carbon and energy compared with those utilized by its phylogenetic relatives.
Grows aerobically and produces catalase and cytochrome oxidase
-The following substrates are utilized as sole carbon sources: glucose, mannitol, d-mannose, sucrose, d-sorbitol, d-arabinose, l-rhamnose, maltose, fructose, d-galactose, erythritol, melibiose, glycerol, cellobiose, raffinose, xylose, melezitose, trehalose, l-proline, l-alanine, l-histidine, gluconate, malate and phenylacetic acid
-It possessed phosphatidylethanolamine and phosphatidylglycerol as major phospholipids
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.<be>
- icy and low-temperature environments
- can survive high salinity environments
- degrades organic materials so it can be taken up by smaller bacteria and organisms
- nothing found on symbiosis yet
- not much understood about their ecological role yet
- does not reduce nitrate or produce hydrogen sulfide
- Marinomonas primoryensis were first isolated from coastal sea ice in the sea of Japan
Marinomonas artica has not been show to cause disease.
