化学试剂.磷酸氢二钾 - The specific subjects as bellow : firstly the two aqueous two - phase system of peg / ( nh4 ) 2so4 and peg / k2hpo4 were compared , then the better system was used for the aqueous two - phase extraction
首先针对聚乙二醇硫酸铵和聚乙二醇磷酸氢二钾这两个双水相体系进行比较，选取较好聚乙二醇硫酸铵的双水相体系用于双水相萃取分离。 - The results of the experimental tests show that nh4cl and k2hpo4 , kh2po4 are the most available nutrents to our isolates when they are degrading oils . the most suitable experinment condition is : temperature being 30 c , initial ph being 7 - 8 , the shaking rate of the culture flasks is 180 r / min , the concentration of nacl is 1 % . the biodegradation results have shown that our 6 isolates have the effective degradation capability to crude oil ; within 6 days the transforing rate of oil by each single strain is more than 60 %
本研究分离出的6株菌，初步鉴定结果为： sy1为微杆菌属、 sy2为诺卡氏菌属、 sy3和sy5为假单胞菌属、 sy4和sy6为芽孢杆菌属；实验结果表明， 6菌株的最佳氮源为氯化铵( nh _ 4cl ) ，最佳磷源为磷酸氢二钾和磷酸二氢钾的混合物，最适生长条件为：温度为30 ，初始ph值为7 8 ，摇床转速为180r min ，盐( nacl )浓度为1 ；通过降解实验得出6株菌对原油都有较强的降解能力，单一菌株在5天后的原油降解率都高于60 ， 6株菌对原油的生物降解反应符合一级反应动力学特征。
