  11. Three phenanthrene - degrading bacteria were isolated from soil samples contaminated by oil, which are capable of using phenanthrene as sole carbon and energy sources, and were identified to be belonged to sphingomonas, strain zx4 as s. paucimobilis, strain zx6 as s. aromaticivorans and strain eva 17 not being identified to species, respectively, based on the results of physio - biochemical tests and the phylogenetical analyses of 16s rdna sequence

    實驗結果分述如下： 1 、本研究從石油污染土壤中分離到3株菲降解細菌（ zx4 、 zx6和eva17 ） ，它們都能以菲為唯一碳源和能源生長。經鑒定3菌株都歸于鞘氨醇單胞菌屬（ sphingomonas ） ，其中zx4菌株為少動鞘氨醇單胞菌（ sphingomonaspaucimobolis ） ， zx6菌株為溶芳烴鞘氨醇單胞菌（ sphingomonasaromatics ） ， eva17菌株比較獨特，尚未能鑒定到種。
  12. There existed differences between the effect of initial ph6 and that of initial ph7 in media on growth and phenanthrene degradation of zx4 strain. compared with initial ph7 of medium, the growth was better in medium at initial ph6, and phenanthrene degradation, however, stagnated almost after 2d of incubation, madding against the complete degradation of phenanthrene. as increasing phenanthrene content, substrate saturation appeared in medium at initial ph6, but not in medium at initial ph7 for growth of zx4 strain

    培養基初始ph對zx4菌株生長和菲降解的影響比較特殊：培養基初始ph6時，與初始ph7相比， zx4菌株的生長較好，但對菲的降解在2d后便基本停滯，不利於菲的徹底降解；培養基初始ph為6時，隨著培養基中菲含量的增加， zx4菌株的生長出現底物飽和現象， tween - 80的加入對其生長呈抑制效應；而初始ph為7時， zx4菌株的生長和菲降解速率始終隨著菲含量的增加而增大， tween - 80的加入對其生長和菲降解速率都有顯著促進作用。
