5. A new desulfurization bioreactor of the fuel oils was designed. The TJQ can grow well with high concentration of DBT In the bioreactor, it can desulfurize the DBT sulfur significantly from 19.2mg/L(0.6mmol/L) to 0.224mg/L(0.007mmol/L) ,and the desulfurization ratio is 98.8% in aqueous media during two days .
1. Analysis of community structure of indigenous microorganisms at S12 block in Shengli OilfieldWith selected media, the community structure of indigenous microorganisms in six water samples (including recycled produced water for flooding reservoir at S12 block in Shengli Oilfield and produced waters from five oil wells of the reservoir) was analyzed.
At 50℃, it can decrease the viscosity of high asphalt oil by 22.2%, and can decrease the solidifying point of high paraffin oil by 2.5℃. At the same time, the strain ZH 20 keeps the characteristic ability of high temperature tolerance and salt tolerance. After growing for 10 generations in liquid paraffin media, the oil degradative functions of the strain ZH 20 were proved to be stable.
转化条件为：30％ PEG6000，50m m ol／LCaCl2 ，于37℃保温20m in．ZH20 具有嗜高胶油和高蜡油的双重性状，50℃条件下使高胶油粘度降低22．2％ ，使高蜡油的凝固点降低2．5℃，且保持了受体菌的耐热和耐盐性能．液蜡培养基连续传代10 次，性能稳定．
