土壤中耐低温石油降解菌的优选、鉴定及降解性能分析
SELECTION,IDENTIFICATION AND DEGRADATION CHARACTERISTICS OF COLD-RESISTANT PETROLEUM-DEGRADING STRAINS IN SOIL
摘要
Abstract
Thirty one strains were isolated under low temperature conditions from oil-polluted soil from the Dagang Oilfield. Preliminary degradation at 10 ℃ with D17 and D24 resulted in degradation of 47.64% and 39.81% respectively. D17 was identified to be Paracoccus sp. , and D24 to be Halomonas sp.. After 15 days of degradation with D17, TPH in the soil phase was 86.5 mg (per 7 g soil) less than control (no strains added); with D24 it was 15.8 mg (per 7 g soil) less than control (no strains added). GC-MS results of D24 indicated that D24 had little effect on degradation of saturated hydrocarbon. However, adding D24 had a significant impact on aromatic components, in which degradation level of heavy aromatic components is higher than light components.关键词
