Abstract

In this paper, the effect of cultivation medium with differential acidity on the dissimilatory sulfate reduction process in bacterium Desulfovibrio piger Vib-7 isolated from the human intestine was studied. Microbiological, biochemical, and biophysical methods of the studies, and statistical processing of the results were used; the obtained data were compared with those from literature. The most intensive growth of intestinal bacterium D. piger Vib-7, sulfate and lactate dissimilation, and sulfide and acetate production was determined at the optimum pH 7.0–8.0. A correlation and cross-correlation analysis of these processes under the effect of differential acidity of the culture medium was carried out. The described results of these studies can be the prospects to clarify the etiological role of these bacteria in the development of inflammatory bowel diseases humans and animals.
