Acidilobus saccharovorans

Description and Significance

A. saccharovorans has a coccus shape with a bundle of flagella. This archaea also has a thick S-layer. A. saccharovorans was isolated from a terrestrial hot spring.

Genome Structure

A. saccharovorans consists of a circular genome with 1,496,453 base pairs. A. saccharovorans have no extrachromosomal elements and have one copy of the 16S-23S rRNA operon. There are 246 genes that are unique for A. saccharovorans.

Cell Structure, Metabolism and Life Cycle

Acidilobus saccharovorans is an anaerobic, organotrophic, thermoacidophilic archaeon. Glucose in A. saccharovorans is metabolized to pyruvate through the Embden-Meyerhof pathway or the Enter-Doudiroff pathway. A. saccharovorans may conserve energy by doing oxidative phosphorylation.

Ecology and Pathogenesis

A. saccharovorans are found on hot springs. They are believed to help with the complex oxidation of organic material.
