Description is based upon a single isolate.
Gram positive filamentous cells with “cross-like” branching , 0.5-0.9/1.8-5.0 µm.
Subterminal/terminal, ellipsoidal endospores (0.5-0.7/0.7-1.0 µm) in unswollen
sporangia. Motile.
Colonies are slightly yellowish, semitransparent & creamy. Grow aerobically.
Alkalitolerant organism,  growth is observed at pH 7.0-10; optimal growth is observed
at pH 9. Growth occurs at 10-45 ºC, optimum temperature is 30 ºC. No requirement of  
NaCl, allantoin or urate  for growth (0 -3% NaCl tolerance).
Bacteria was isolated from degraded thallus of brown alga Fucus evanescens , Kraternaya Bight, Pacific Ocean.
Unknown.

Positive results for hydrolysis of urea , gelatin & starch. Weak reaction for catalase &
nitrate reduction.

Negative results for hydrolysis of casein, citrate utilization, hydrolysis of Tween 40 & 80.
