| 摘 要： | 对2株海洋石油烃降解菌(HD-1和HD-2)进行了研究;采用气相色谱法分析了这2株菌对正构烷烃组分的降解情况。结果表明HD-1菌株对正构烷烃的降解性能优于HD-2菌株。碳链的长度对降解率有显著影响。C11能分别被HD-1和HD-2降解90.9%和73.8%,但C25却只能被降解73.3%和27.7%。采用麦饭石、孔质砂和稻壳碳固定混合菌液后,对培养液中柴油的去除率都明显高于未固定化的菌液的去除率,其中麦饭石固定化菌的去除率最高,达到98%。

| Abstract: | Two petroleum hydrocarbon degrading bacteria strains (named HD1 and HD2) were studied in this research. Gas chromatography was performed on n-alkanes degradation. The most efficient n-alkanes degrader was HD1. The chain length influenced n-alkanes biodegradation to a significant extent. C11 was almost completely (90.9%, HD-1) and highly (73.8%, HD-2) degraded. Of the initial amount of C25, 27.7%( HD2) or 73.3%( HD1) were degraded. About 98% oil was degraded by immobilized strains which were adsorbed by medicalSstones. |
