Winogradskyella poriferorum


Winogradskyella poriferorum (designated strain UST030701-295T) are gram negative, rod-shaped cells. They show rapid gliding motility. Colonies are yellow, circular, 2-4 mm in diameter, and have a smooth surface after cultivation on marine agar. Cells are strictly aerobic. Cells grow at temperatures between 12 and 44 ͦ C and at a pH between 6.0 and 10.0. For growth the cells require 1.0-4.0% NaCl and the G+C content of the DNA is 32.8mol%.

Include as many headings as are relevant to your microbe (including things like cell metabolism, ecology, pathology, application to biotechnology). Or, if your microbe is very new and not well studied, then include a heading or two with more description about its native environment or something related to its lifestyle.


The strain UST030701-295T was isolated from the surface of the sponge Lissodendoryx isodictyalis in the Bahamas and lives in a marine environment. They are highly associated with sponges.


The sole carbon source of Winogradskyella poriferorum is aesculin. The strain's main fatty acids are iso-C15 : 1, iso-C15 : 0, iso-C15 : 0 2-OH, iso-C15 : 0 3-OH, iso-C16 : 0 3-OH, C16 : 1ω7 and iso-C17 : 0 3-OH.


The strain UST030701-295T is sensitive to the antibiotics ampicillin (0·5 μg), benzylpenicillin (0·5 μg), chloramphenicol (1·0 μg), streptomycin (10 μg) and tetracycline (0·5 μg). It is resistant to the antibiotic kanamycin.

Current Research

The production of poly-ethers in Winogradskyella poriferorum and the natural abundance of these poly-ethers are being studied. Because the poly-ethers that are produced in Winogradskyella poriferorum have a potent bioactivity, it makes them good applicants as ingredients in antifouling applications.
