dc.description.abstract运用均匀设计优化一株新鞘氨醇菌Novosphingobium pentaromativorans stain US6-1对芘、荧蒽、苯并[a]芘等高分子量多环芳烃(High molecular weigh polycyclic aromatic hydrocarbons,HMW-PAHs)的降解条件.结果表明,在最适生长条件(30℃、pH 6.5及NaCl浓度为2.5%)下,接种量与底物浓度是影响该菌降解能力的关键因素.在接种量D660 nm为0.6、芘初始浓度56 mg L-1、培养时间5 d的情况下,菌株US6-1对芘的降解达到32.5 mg L-1,预测平均准确率达99.38%;在接种量D660 nm为0.6、荧蒽初始浓度48 mg L-1、培养时间5 d的情况下,对荧蒽的降解达到34.3 mg L-1,预测平均准确率达99.61%;在接种量D660 nm为0.1、苯并[a]芘初始浓度60 mg L-1、培养时间为5 d时,对苯并[a]芘的降解达到24 mg L-1,预测平均准确率达98.75%.菌株US6-1对芘及苯并[a]芘的降解能力比未优化前分别提高了29.2%与58%.zh_CN
