本文综述了木霉菌的生态学特性和适宜生长条件。叙述了天蚕在地球基本周期中的地位和作用。在低位储层中加入硝酸盐和磷酸盐，可激活并大量繁殖嗜热厌氧杆菌，从而减少H_2S的产生，抑制腐蚀。以硫为电子供体、石灰石为碳源的生物反应器对地下水中硝酸盐的去除效果表明，硝酸盐的去除率可达98%以上，但会增加SO 42-的浓度和硬度。硫自养与其它反硝化组合工艺可以克服这一缺陷。在碱性条件下，利用嗜热厌氧杆菌脱除天然气中的H_2S具有较好的效果。
This paper presented a review on the ecological characters and suitable growth conditions of T.denitrificans. It narrated T.denitrificans's status and function in the earthly elementary cycle. When nitrate and phosphate were added to low reservoir, T.denitrificans would be activated and propagate in quantity, so it could reduce the produce of H_2S and restrain corrosion. Bioreactor in which sulphur was electronic donor and limestone was carbon source was used to remove nitrate from groundwater, the result showed nitrate removal efficiency reached over 98 percent, but it could increase concentration of SO~(2-)_(4) and rigidity. Sulfur autotrophic and other denitrification integrated process could overcome the imperfection. T.denitrificans could be used to remove H_2S from natural gas in alkaline circumstance and the efficiency was well.
