Gram-positive rods, 1.1-1.9 x 0.3-0.5 µm. Cells in older cultures tend to be shorter
and coccoid. Non-motile. Non-spore-forming. Rod-coccus life cycle is not observed.
Colonies are pale yellow and white, circular, have an entire margin and are opaque
within 24 h with a diameter of approximately 2 mm on nutrient agar. Growth occurs at
10-37 ºC (optimum 30 ºC), pH 6.0-10.0 (optimum pH 8.0), and in up to 15% (w/v) NaCl
(optimum 4%). Aerobic.
Isolated from the rhizosphere of Salicornia brachiata from the coastal region of Bhavnagar district, Gujarat, India.
Undetermined.

Positive results for amylase, catalase, pectinase, gelatinase, protease and lipase.
