Acidiplasma sp. BR-02 Transcriptome or Gene expression

Extremely acidophilic iron and sulfur-oxidizing bacteria and archaea are used for processing of different sulfide ores and concentrates (biohydrometallurgical technologies); therefore, study of its metabolic pathways and their regulation is an urgent task. Thus, the goal of the present work was to compare differential gene expression in the thermoacidophilic arhaeal strain, representative of the genus Acidiplasma, one the predominant microbial group in bioleach reactors, during the growth in the presence of ferrous iron, and elemental sulfur as well as pyrite and arsenopyrite, which are the most widespread sulfide minerals, and to obtain novel data on the mechanisms of interaction of microorganisms and sulfide minerals.
