Abstract

Background and Objective: Toxic gases are one of important parameters in water and high concentration of these factors is caused problems in aquatic organisms. In WARM WATER FARMs, decreasing of dissolved oxygen and pH are caused increasing of SH2 concentration. One of decreasing methods of SH2 is use of oxidizing bacteria. The aim of this study, isolation of sulfur oxidizing bacteria those are able to growth in aerobic and anaerobic and neutral pH and also reducing of nitrogen in different forms. Materials and methods: After sampling of water and sediment, culture was done in T2 medium and nutrient broth included sodium sulphite. Samples were incubated at 25-30oC for 4-6 days. Final culture from positive tests, were done in T2 medium agar (15% agar agar) and nutrient agar included sodium sulphite. Microscopy, microscopy characterization and biochemical tests were done for isolated colonies. Evaluation of sulfur oxidation in various scale (bench, aquariums, fiberglass and farm) were done in different time. Effects of pH, aeration and sodium sulphite on different treatments were also surveyed. Results: The results were showed that two sulfur oxidizing bacteria including Tiobacillus denitrificans and PARACOCCUS denitrificans were isolated that are able to growth in pH 7-8 and 25-30oC and be and not to be of aeration was any effect on examination. Conclusion: The conclusion was showed that isolated of bacteria with other bacteria such as nitrosomonas and nitrobacter are able to decrease combination of ammonia, nitrite and SH2.
