| Pseudogulbenkiania gefcensis |
Colonies on nutrient agar after 48h incubation at 32 ºC are small, round, entire,
convex, white and 1.0-1.3 mm in diameter. Growth occurs at 25-40 ºC, optimally at 32
ºC. Can grow in pH 6.0-8.0, optimally in pH 6.0. Can grow in 0.3-2% (w/v) NaCl,
optimally in 0.7% NaCl. Aerobic.
