As a new energy, biogas is used more and more widely. It is strictly stipulated in the environmental protection standards of our country. When using biogas energy, the content of H2S in biogas is clearly stipulated. Therefore, H2S must be removed before biogas is used. There are three methods of biogas desulfurization, in fact, biological desulfurization is the most stable, efficient and pollution-free. In the process of biological desulfurization, we use more microorganisms are Thiobacillus ferrooxidans and Thiobacillus denitrificans. We talked about Thiobacillus ferrooxidans last time. In this issue, we will introduce the situation of Thiobacillus denitrificans.

脱氮硫杆菌是一种专性无机化能自养型细菌，可以在氧化硫化物的过程获得能量，所以他们成为在废水同步脱硫反硝化处理工艺中的主要功能微生物。

Thiobacillus denitrificans is a kind of specific inorganic energy autotrophic bacteria, which can obtain energy in the process of sulfide oxidation, so they become the main functional microorganisms in the process of simultaneous desulfurization and denitrification of wastewater.

脱氮硫杆菌分布很广，可在10～37℃，pH为4.0～9.5的条件下生长，适生长温度为28～30℃，适pH 6.5～7.0。脱氮硫杆菌对高盐度环境的适应性不强。脱氮硫杆菌能够利用的氮源范围很广，可以是氨盐、硝酸盐、亚硝酸盐以及氨基酸等，在厌氧条件下，硝酸盐又被作为电子受体而被还原。在硫循环体系中，好氧条件下，脱氮硫杆菌以氧为电子受体氧化还原硫化合物而获得能量。厌氧条件下，脱氮硫杆菌以反硝化反应的方式同时参与硫、氮循环,以硝酸盐中的氧来氧化硫化合物。

Thiobacillus denitrificans are widely distributed and can grow at 10-37 C and 4.0-9.5 pH. The optimum growth temperature is 28-30 C and the optimum pH is 6.5-7.0. Thiobacillus denitrificans is not adaptable to high salinity environment. Thiobacillus denitrificans can utilize a wide range of nitrogen sources, such as ammonia, nitrate, nitrite and amino acids. Under anaerobic conditions, nitrate is reduced as an electron acceptor. In the sulfur cycle system, under aerobic conditions, Thiobacillus denitrificans use oxygen as electron acceptor to oxidize and reduce sulfur compounds to obtain energy. Under anaerobic conditions, Thiobacillus denitrificans take part in both sulfur and nitrogen cycles in the way of denitrification, and oxidize sulfur compounds with oxygen in nitrate.
