Bacillus

Cells are straight, rod-shaped, 0.5 to 2.5 m m * 1.2 to 10 mu, often arranged in pairs or chains, with rounded ends or square ends.

Bacillus sp.

Latin name: (Bacillus, Cohn, 1872)

2 morphological description editing cells are straight, rod-shaped, 0.5 to 2.5 mu m x 1.2 to 10 mu m, often arranged in pairs or chains, with rounded ends or square ends. Most of the cells stained in young cultures were gram positive and had flagella with peripheral flagella. Spores oval, oval, cylindrical, round, resistant to many adverse environments. Each cell produces a spore, which is not inhibited by oxygen. Aerobic or facultative anaerobic with a variety of physiological properties of heat, pH, and salt. Heterotrophic bacteria with a fermentation or respiratory metabolism type. Usually, the enzyme is positive. Found in different habitats; a few species are pathogenic to vertebrates and non vertebrates.

Type subtilis: Bacillus subtilis (Bacillus).

3 detailed information on the compilation of Bacillus spp.

Bacillus

1 genera of the genus Bacillus; Gram-positive bacteria. Producing spores, aerobic or facultative anaerobic, mostly dynamic, without

capsule, mostly hemolytic, usually catalase positive. G+C molar content in DNA was 32 ~ 62%. The genus includes Bacillus anthracis that is pathogenic to humans and animals, Bacillus cereus causing food poisoning, and nearly 50 species of non pathogenic Bacillus subtilis, Bacillus cereus, and Bacillus cereus.

Gram positive bacteria. Producing spores; aerobic or facultative anaerobic. Most powerful, without capsule, mostly hemolytic, usually catalase positive. Bacillus anthracis including pathogenic Bacillus anthracis, food poisoning causing Bacillus cereus, non pathogenic

Bacillus subtilis, Bacillus cereus, Bacillus cereus and the like.

Bacillus anthracis capsule, no flagella in artificial culture bacteria showed a long chain arrangement, the formation of oval spore; Bacillus bacteria in the central, but not greater than the cell width; aerobic; spore resistance is very strong, can survive for decades in the dry state; the bacteria mainly herbivores disease, disease a sharp, high mortality; the susceptibility of bacteria by only herbivores, broken skin, gastrointestinal or respiratory tract invades the body, high mortality; available antibiotics and sulfa treatment.

4 lactic acid production, a common feature of lactic acid in the genus Bacillus

There are also a number of lactic acid producing bacteria in the genus bacillus, among which are economically important species. For

these lactic acid bacteria, Bacillus should belong
