摘　　要：以乙酸钠、丙酸钠为底物,研究不同浓度的丙烯酸盐及对甲基苯磺酸盐对产甲烷活性的影响。结果表明,丙烯酸盐及对甲基苯磺酸盐对丙酸为底物产甲烷活性的抑制作用强于乙酸为底物。丙烯酸盐对乙酸和丙酸产甲烷活性抑制的半效应浓度(EC50)分别为717和235 mgL。对甲基苯磺酸根浓度在10 000 mgL以下对乙酸的产甲烷活性无明显抑制作用,对丙酸产甲烷活性抑制的EC50为9 500 mgL。丙烯酸盐及对甲基苯磺酸盐共同存在时,对产甲烷活性的抑制未表现出明显的协同作用。Influence of acrylate and p-toluenesulfonate on methane-producing activity with acetic acid or propionic acid as substrate was investigated. It was indicated that inhibition of methane-producing activity by both acrylate and p-toluenesulfonate with propionic acid as substrate is more significant than that with acetic acid as substrate. The semi-effective concentrations （ECho） of acrylate for inhibition of methane-producing activity with acetic acid and propionic acid as substrates were 717 and 235 mg/L, respectively. There was no significant inhibition effect on methane production with acetic acid as substrate by p-toluenesulfonate below 10 000 mg/L, while ECso for inhibition of methane-producing activity with propionic acid as substrate was 9 500 mg/L. When acrylate and ptoluenesulfonate coexisted in the system, no significant synergistic effect was observed on inhibition of methaneproducing activity.
