摘要: The principle involved in the phenanthrene degradation is regarded as key to unlock mechanisms governing pathway of other polycyclic aromatic hydrocarbons. Past studies have made some proposals via metabolite analysis. In this study, two dominating species (phn01 and phn02) were isolated from oil contaminated soil used lab-scale experiment degradation. GC/MS results revealed metabolites pyruvate, phthalate, 1-hydroxy-2-naphthaldehyde 9-phenanthrol at retention time 12.01, 15.34, 16.82 18.16 min, respectively. A new proposal was derived. Selective indicated relationship coordination between these species, one which mainly responsible for pyruvate production consumption. Pyruvate played a role microbial demarcation might be closely associated with invoking signal community during biodegradation.
