gubbeenense Brennan, Brown, Goodfellow, Ward, Beresford, Vancanneyt, Cogan and Fox, 2001.
Gram-positive, small, slender rods, 0.5-2.0 µm length, arranged in V-shapes, typical
coryneform morphology. Motile. Non-spore-forming.
Colonies are cream, irregular, matt, slightly raised, 1-5 mm in diameter on Peptone
Yeast extract Agar after 5 days at 30 ºC. Facultative anaerobe. Grows in 5-12% NaCl
media. No growth at 37 ºC.
Isolated from surface of Gubbeen, Irish farmhouse smear-ripened cheese.
