Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Bacillaceae, Genus Bacillus, Bacillus jeotgali Yoon, Kang, Lee, Kho, Choi,
Kang and Park 2001. Description is based on two isolates.
Gram-variable rods, motile by peritrichous flagella, 0.8-1.1 x 4.0-6.0 µm. Produce
ellipsoidal endospores in swollen sporangia.
Colonies are cream-yellow or light orange-yellow, smooth and flat with irregular
margins on trypticase soy agar supplemented per liter with 24g NaCl,7g MgSO4 .
7H2O, 5.3g MgCl2 . 6H2O, 0.7g KCl and 0.1g CaCl2 (pH 7.5). Grow poor in nutrient
agar and trypticase soy agar without added salts. Facultatively anaerobic. Grow at pH
6-8 and 10-50 ºC (optimum 30 ºC). Grow in nutrient broth with 2-13% NaCl added.
NaCl is required for growth. Allantoin and urate are not required for growth.
Isolated from jeotgal, a Korean traditional fermented seafood.
