Bacillales
Bacillus anthracis
Bacillales form an order of Gram-positive bacteria from the class of Bacilli. Many of these usually rod-shaped bacteria are aerobic, they can not live without oxygen. An important feature of many representatives is the ability under adverse conditions (eg, lack of food, temperature, etc. ) to form endospores. The name derives from the Bacillales was the genus Bacillus from the family Bacillaceae.
System
The following families are currently assigned to the order Bacillales:
- Alicyclobacillaceae
- Bacillaceae
- Listeriaceae
- Paenibacillaceae
- Pasteuriaceae
- Planococcaceae
- Sporolactobacillaceae
- Staphylococcaceae
- Thermoactinomycetaceae
Furthermore there are genres ( eg Exiguobacterium, Gemella or solos Bacillus ), which were previously assigned to any of this family. But studies of the 16S rRNA sequence revealed a close relationship, so that these types were asked to order Bacillales.
