Metagenome analyses of microbial population in geotextile fabrics used in permeable reactor barriers for toluene biodegradation

Toluene is one of the hydrocarbons that contaminate soil and groundwater and has a high cost to remediate, which makes it an environmental pollutant of concern. This study aimed to find out bacterial distribution from nonwoven geotextile (GT) fabric specimens in a pilot-scale permeable reactive barrier (PRB). Upon 167 days of incubation with the addition of toluene, the microbial community on the GT surfaces (n = 12) was investigated by the 16S rRNA metagenome sequencing approach.

甲苯（Toluene）是污染土壤与地下水的烃类污染物之一，其修复成本高昂，属于备受关注的环境污染物。本研究旨在探究中试规模渗透性反应屏障（permeable reactive barrier，PRB）内非织造土工布（nonwoven geotextile，GT）样本的细菌分布特征。在添加甲苯并经167天孵育后，采用16S rRNA宏基因组测序方法，对土工布表面（n=12）的微生物群落进行了分析。
