Abstract
Stable isotope probing (SIP) was used to identify the aerobic toluene-degrading microorganism in soil microcosms. Several approaches (terminal restriction fragment length polymorphism, 16S rRNA gene sequencing, and quantitative PCR) provided evidence that the microorganism responsible was a member of the genus Polaromonas and could grow on toluene. This microorganism also transformed benzene, but not m-xylene or cis-dichloroethene.
摘要
稳定同位素探测（SIP）被用于鉴定土壤微宇宙中的好氧甲苯降解微生物。几种方法（末端限制性片段长度多态性、16S rRNA 基因测序和定量 PCR）提供的证据表明，负责的微生物是极地单胞菌属的一个成员，能够以甲苯为生长基质。这种微生物还能转化苯，但不能转化间二甲苯或顺式二氯乙烯。
