| Gulbenkiania indica |
Colonies on nutrient agar are smooth, mucoid, round and cream-coloured, 1.5-2 mm
in diameter. Growth occurs at 15-45 ºC, optimally at 30–37 ºC. Can grow in pH 5.0-
11.0. Can grow on on MacConkey agar. Can grow in 1.0 % (w/v) NaCl but not in 2%
NaCl. Aerobic. No anaerobic growth in the presenceof nitrate.
