英文摘要	Soil microbial community structures and enzymatic activity are important indicators for judging biochemical process intensity and soil quality. Non-thermal discharge plasma (NDP), an advanced oxidation technique, has received great attention in soil remediation. Potential impact of NDP treatment on microbial community structures and enzymatic activities in uncontaminated soil samples was evaluated in this study. The NDP treatment significantly altered soil microbial community structures and enzymatic activity. The exposure of soil samples to NDP decreased the enzymatic activities including glutamic acid enzyme, arylsulphatase, leucine enzyme, acetyl glucosaccharase, glucosaccharase, cellulose, phosphatase, and ligninase. The contents of some soil microbes including Gram-negative bacteria, Fungi, Anaerobes, AM Fungi, Eukaryotes, and Actinomycetes also decreased after NDP treatment, as well as the diversity index and equitability index of the soil microbes. In addition, the total phospholipid fatty acid (PLFA), Fungi PLFA, bacteria PLFA, and Actinomycetes PLFA of the soil microbes were also reduced after treatment. Principal component analysis confirmed these changes. Actinomycetes and Fungi were the most sensitive microbes to the NDP, and Phosphatase activity and Cellulose activity were relatively insensitive to the NDP. The potential impacts could be attributed to chemically active substances and ultraviolet irradiation.
