摘　　要：从任丘油田分离到两株异养型细菌D-1-1和D-2-1,经鉴定分别为门多隆假单胞菌(Pseudomonas mendocoas)和争论产碱生物变型Ⅰ (Alcaligenes paradoxus biovar Ⅰ)的菌株。它们可以利用二苯噻吩(Dibenzothiophene,简称DBT)作为生长的碳源,将DBT转化成为水溶性有机硫化物。两菌于15天内可以脱除煤炭中有机硫达22.2—32.0％。Two strains of heterotrophic bacteria, D-l-1 and D-2-1, was isolated from Ren Qiu Oil Field (China) and identified as Pseudomonas menaocoas and Alcaligenes paradoxus biovar I , respectively. These strains are able to utilize Dibenzothiophene (DBT) as the carbon source for growth, and convert DBT into water-soluble organic compounds containing sulfur. They can remove 22. 2-32.0% of the organic sulfur from coal samples for 15 days.
