Species description is based on a single isolate.
Gram-negative rods. Motile.
Colonies on Luria Bertani agar are white in colour, circular and smooth. Growth
occurs at 20-40 ºC (optimally at 30 ºC), in 0-8% NaCl (1.0% optimally) and at pH
5.0-10.0 (optimally at pH 7.0). Facultatively anaerobic.
Isolated from the roots of Phragmites karka growing in Chilika Lagoon, Odisha, India. Nitrogen-fixing bacterium.
Sensitive to chloramphenicol, nalidixic acid, carbenicillin, ofloxacin, nitrofurantoin, erythromycin, sulphamethizole, kanamycin,
tetracycline, neomycin, ampicillin, rifampicin, gentamicin, co-trimoxazole, amikacin, ciprofloxacin, furazolidone, amoxycillin and
norfloxacin. Resistant to bacitracin and streptomycin.
Undetermined.
