Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Bacillaceae, Genus Bacillus, Bacillus algicola Ivanova, Alexeeva, Zhukova,
Gorshkova, Buljan, Nicolau, Mikhailov and Christen 2004.
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
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.
