Abstract

Abstract: The mixed sulfate-reducing bacteria were screened by selecting the medium. At the same time, the optimum growth conditions were studied. The effects of inoculation amount, temperature, initial pH and Fe²⁺ on the growth of the mixed sulfate-reducing bacteria were investigated. The results showed that the mixed sulfate-reducing bacteria grew best when the inoculation amount was 10%, the temperature was 35 °C, the initial pH was 6.5, and the Fe²⁺ in the medium was 200 mg/L.

Key words: mixed sulfate-reducing bacteria, inoculation amount, temperature, initial Fe²⁺
