摘要：The emission of hydrogen sulphide (H2S) from industrial processes causesodour nuisance to the surrounding community. Thus, the ability of sulphur oxidizing bacteria could eliminate H2S by changing it into non-odorous elemental sulphur or sulphate. In this study, the isolate bacteria of Paracoccus solventivorans ATCC 700252 demonstrated pH reduction from pH 8 to about pH 5.27 with sulphate content production of454.0 g/ml. The growth of Paracoccus sp. was increased using sulphur as elemental carbon and oxygen as electron acceptor. The optimum temperature and pH of Paracoccus sp. were in the range of 30°C to 40°C and pH 7.00 to pH 8.00, respectively. The utilization of Paracoccus sp. will create a potential application for H2S removal and preserve the environment from further odour pollution.
