Understanding Stress Response to High-Arsenic Gold-Bearing Sulfide Concentrate in Extremely Metal-Resistant Acidophile <i>Sulfobacillus thermotolerans</i> by Anna Panyushkina, Daria Matyushkina, Olga Pobeguts

“…The goal of this research was to gain insight into the defense strategies of the acidophilic bacterium <i>Sulfobacillus thermotolerans</i>, which dominates microbial communities functioning in industrial biooxidation processes at >35 °C, against the toxic effect of the high-arsenic gold-bearing sulfide concentrate. In addition to extreme metal resistance, this acidophile proved to be one of the most As-tolerant microorganisms. …”
