Structural and functional changes in the cells of microorganisms under the influence of hydrogen sulfide

Abstract

Influence of hydrogen sulfide on the survival of Pichia guilliermondii yeasts and Bacillus subtilis і Desulfovibrio desulfuricans bacteria cells was investigated. The most sensitive to the influence of hydrogen sulfide were D. desulfuricans, and the most resistant – P. guilliermondii. Hydrogen sulfide caused changes in cell ultrastructure. In B. subtilis and P. guilliermondi, the plasmolysis, membrane structures and cell wall destruction and accumulation of metals sulfides in the cytoplasm were observed.
