Streams Impacted By Hydraulic Fracturing Activity--Microcosms with Biocides

This study aimed to understand the effect hydraulic fracturing (HF) impacts have on aquatic microbial community. Water from 6 streams, three impacted by HF (HF+) and three not impacted (HF-) were used to construct microcosms. Two different experiments were run. The first set of microcosms were amended with the biocide glutaraldehyde. The second set of microcosms were amended with the biocide DBNPA. Difference in microbial responses and degradation rates between HF+ and HF- were explored.本研究旨在探究水力压裂（Hydraulic Fracturing, HF）对水生微生物群落的影响。研究选取6条溪流的水体构建微宇宙体系，其中3条取自受HF影响的溪流（记为HF+组），另外3条取自未受HF影响的溪流（记为HF-组）。共开展两组独立实验：第一组微宇宙体系中投加杀生物剂戊二醛，第二组微宇宙体系中投加杀生物剂DBNPA。本研究对比分析了HF+组与HF-组在微生物响应特性与降解速率上的差异。
