Dissimilatory sulfate reduction in the intestinal sulfate-reducing bacteria Sulfate-reducing bacteria (SRB) are common in anaerobic areas of soils, wetlands, fresh and marine waters, and available in the microbiocenosis of large intestine of humans and animals [1,63]. These microorganisms, dissimilating sulfate to hydrogen sulfide, are involved in the process of biogeochemical sulfur cycle in nature [63]. The sulfate dissimilation process is called the „dissimilatory sulfate reduction” or „sulfate respiration” [54]. Intensive sulfate reduction by SRB, and accordingly the accumulation of toxic hydrogen sulfide in the intestine, is leading to the development of various diseases [12, 16, 46, 49, 55]. SRB and the products of their metabolism are often found during bloody diarrhea and abdominal pain [51, 55]. It is believed that they can cause weight loss, frequent defecation, arthritis, rheumatic diseases, increased intestinal permeability, ulcerative colitis, and malaise, in general [12, 13, 15, 17, 46, 49, 55].
