| 摘 要： | 由土壤中分离得到一株自养型的脱氮硫杆菌(Thiobacillus denitrigioans，硫杆菌属，硫杆菌科，革兰氏阴性化能自养细菌)，该菌株的最佳生长pH为7．0。将此菌株与硫酸盐还原菌(Sulfate Reducing Bacteria,SRB，脱硫弧菌属，革兰氏阴性厌氧细菌)混合培养，测定SRB的菌量变化，结果表明，脱氮硫杆菌的生长抑制了硫酸盐还原菌的生长，降低了SRB的腐蚀性的代谢产物硫化物的浓度，腐蚀速率降低，有利于防治SRB引起的微生物腐蚀。

| Abstract: | In this paper, a strain of Thiobacillus denitrificans was isolated from soil The optimal pH for growth was 7 0 In mixed cultivation with SRB, the number of SRB was determined The results show that Thiobacillus denitrificans can restrain the growth of SRB, and decrease the concentration of corrosive metabolic production caused by SRB The corrosion rate reduces as a result So it is propitious to prevent and cure the corrosion caused by SRB |
