%X 研究了一株氧化硫硫杆菌的氮代谢。此菌生长代谢过程中能够很好的以铵盐作为氮源,驯化后也能很好的以尿素为氮源。且驯化后能以Fe~(2+)为能源,驯化后在尿素浓度为0.04g/L,Fe~(2+)浓度为0.04～0.10mol/L时其生长最快代谢最旺盛。接种在此条件下培养的细菌对煤中的黄铁矿硫的脱出率可达51%。 The nitrogen metabolize of Thiobacillus thiooxidans was investigated in the text.The results show that ammo- nium could be used efficiently and urea also could be used efficiently after induction period.After induction the Fe~(2+) could be used too.And it can grow most quickly with urea in 0.04g/L and Fe~(2+) in 0.04～0.10mol/L.The desulphuri- zation efficiency of pyrite sulfur in coal pyrite exposed was 51% while inoculating the bacteria seeds grown on Fe~(2+)
