The Alicyclobacillaceae are a family of gram-positive bacteria .
features
The Alicyclobacillaceae are mostly aerobic (requiring oxygen), immobile, rod-shaped bacteria. The formation of endospores also occurs. The species are usually acidophilic (acid-loving) and thermophilic ( heat-loving ). So shows z. B. Kyrpidia tusciae optimal growth at 47 to 65 ° C, the species of Alicyclobacillus at temperatures between 35 and 65 ° C.
Systematics
The genera Sulfobacillus and Pasteuria used to belong to the family. On the basis of 16S rRNA analyzes, they are now placed in other families. Sulfobacillus now belongs to the order Clostridiales and Pasteuria was placed in its own family, the Pasteuriaceae . Pasteuria is an obligate parasite of invertebrates , Sulfobacillus is thermophilic with temperatures of 40 to 55 ° C for optimal growth.
In August 2018, the following genera were assigned to the family:
- Alicyclobacillus Wisotzkey et al. 1992 emend. Karavaiko et al. 2005 (the type genus of the family)
- Effusibacillus Watanabe et al. 2014
- Kyrpidia Klenk et al. 2012
- Tumebacillus Steven et al. 2008
ecology
The bacteria were found among other things generally in normal soils as well as in water and soils from geothermal sources . Due to its acid resistance and heat resistance, the species Alicyclobacillus acidoterrestris can also appear as a fruit juice spoiler.
