摘　　要：从被原油污染的土壤中驯化、筛选、分离得到具有自主知识产权的脱硫真核微生物烟曲霉ZJ-1（Aspergillus fumigatus Fresen．ZJ-1）。该烟曲霉ZJ-1在pH值为7、NaCl浓度为5g／L、温度为30℃的条件下，生长状况较好，可耐受3～11范围的pH值变化和25g／L NaCl形成的渗透压，具有较强的环境适应能力。该烟曲霉可以直接脱除油品中的有机硫，有一定的实际应用价值。The fungus of desulfuration was obtained from the crude oil polluted soil through acclimation, screening and separation. It was identified as Aspergillus fumigatus Fresen. ZJ-1. The Aspergillus fumigatus Fresen. ZJ-1 grew well at a temperature of 30 ℃,a pH of 7 and with a NaC1 concentration of 5 g/L, besides, it could stand the pH range of 3- 11 and an osmotic pressure from a NaCl concentration of 25 g/L, having good acclimatization ability. Said fungus could be used to remove organic sulfur from crude oil,diesel ruel and so on.
