Anaerobic sulfate reducing bacteria are ubiquitous in the environment. They can found in secondary oil recovery effluents, estuarine waters, deep wells, cooling waters, metalworking fluids, water-based hydraulic fluids, and petroleum based products. Sulfate reducing bacteria are responsible for fouling, objectionable hydrogen sulfide odors, corrosion of metals, and pitting of concrete. It is essential that these organisms be monitored and controlled to prevent damage caused by their metabolic activities.
The Sani-Check SRB is a sulfate reducing bacteria test kit that contains tubes of culture media specifically formulated to promote the growth of sulfate reducing bacteria. This test kit is designed to be used in areas where little or no formal laboratory facilities are available. Everything needed to perform 25 tests is contained in the test kit.
The most common sulfate reducing bacteria associated with contamination of the industrial environment are found in the genera Desulfovibrio and Desulfotomaculum. When sulfide is liberated, it reacts with iron in the tubed culture medium to form iron sulfide, a black precipitate. The degree to which the medium blackens, along with the length of time it takes to change color, allows for an estimated count of sulfate reducers to be made. Detailed instructions describing the quantitative interpretations are included with each test kit.
