Colonies are tan. Aerobic, facultatively anaerobic. Growth occurs at 28-40 ºC, but not
at 4 ºC or 45 ºC. Grows at pH 5-8. Grows in media below 1.5% NaCl. Can grow on  
5% sheep blood agar, chocolate agar and Luria agar.

Lau et al. 2006, type species of the genus.
Gram-negative, straight or slightly curved rods, 1-7 μm in length. Motile by one polar
flagellum. Spores are not formed.
Isolated from humic-lake samples collected from northern Wisconsin, USA.
Sensitive to chloramphenicol, kanamycin, spectinomycin, tetracycline and trimethoprim. Resistant to ampicillin, rifampicin and
streptomycin.
Undetermined.
