【摘要】：以正十六烷无机盐培养基为选择培养基,从武汉石化输油管附近土壤中筛选出了1株高效降解长链烷烃的菌株C3。采用摇瓶实验,研究了菌株C3降解正十六烷的降解条件、降解动力学及降解机理。菌株C3降解正十六烷的最适宜条件为温度35℃、初始p H=7、摇床转速150 r/min。动力学研究显示,在底物质量浓度为1 000 mg/L时,其降解动力学拟合结果符合Monod方程,半饱和常数Ks=609.8 mg/L,最大降解速率v_(max)=62.1mg/(L·h)。对C3降解正十六烷产物进行红外光谱及GC/MS分析,推测该降解方式为末端氧化。
[Abstract]:Using cetane inorganic salt medium as the selective medium, a strain C3 was selected from the soil near the oil pipeline of Wuhan Petrochemical Company to degrade long-chain alkanes efficiently. The degradation conditions, kinetics and mechanism of C _ 3 degradation of n-cetane were studied by shaking flask test. The optimum conditions for C _ 3 degradation of n-cetane were as follows: temperature 35 鈩，
