Abstract
The growth curve of Thiobacillus denitrificans and pH of the culture media during the domestication process were determined to make sure the optimum condition for the removal of nitrate and sulfide in highly-concentrated wastewater.Then the ratio of sulfide to nitrate and the removing rate of NO3-were also examined in this paper.The results showed that when the S2-concentration in wastewater was 400 mg/L and the ratio of sulfide to nitrate was 5:3,the removing rate of NO3-could reach 63.19%,and S2-could simultaneously be converted into sulfate or elementary sulfur.These results indicated that Thiobacillus denitrificans had application potential in pollution control for nitrate and sulfide in wastewater.

期刊介绍：
The “Chinese Journal of Applied and Environmental Biology” is a national scientific and technological journal published both at home and abroad. It was started in 1995 and became bimonthly in 1999, and now it is a core journal for applied and environmental biology in China. It aims to introduce and exchange the new achievements, new technologies, new methods and new progresses made from the research fields of biology and its related disciplines both in China and abroad; enhance scientific and technological research serving for the development and construction of national economy, and improvement of people’s living standards.
