mary name="EnDivSummary">Functional microbes, peat, and aquifer medium were used to construct biobarrier for in-situ remediation of diesel contaminated groundwater. The results indicated that each part of biobarrier had abundant functional microbes, and the microbial community in the structures had a resemblance in species, richness, homogeneity, carbon source utilization, and catabolic characteristics. The functional microbes in biobarrier could maintain relatively higher microbial quantity, degradatable properties and stable community diversity for a long time.
