Abstract

The purpose of this study was to demonstrate the inhibitory effect of chemicals on methane emissions in paddy soil. We found that (4-hydroxyphenyl) chloromethanesulfonate (C-1) has a methanogenic inhibition activity, and we studied its inhibition mechanism using laboratory tests. The study found that C-1 treatment of flooded soil did not significantly affect the bacterial community but rather the archaeal community; particularly, Methanosarcina spp. C-1 strongly inhibited the aceticlastic methanogenesis route. It was suggested that the inhibitory target of C-1 was different from the well-known methanogenic inhibitor 2-bromoethanesulfonate, which targets methyl-coenzyme M reductase of methanogen. In addition, C-1 had a secondary effect of inhibiting the dechlorination of chlorophenols. Although field trials are required as the next development step, C-1 can be used to reduce methane emissions from paddy fields, one of the largest sources in the agricultural sector.

研究(4-羟基苯基)氯甲烷磺酸盐对甲烷生成和脱氯的抑制作用。
本研究的目的是证明化学物质对稻田土壤中甲烷排放的抑制作用。我们发现(4-羟基苯基)氯甲磺酸盐(C-1)具有抑制甲烷生成的活性,并通过实验室试验研究了其抑制机制。研究发现,C-1 对淹水土壤的处理对细菌群落没有明显影响,但对古细菌群落有明显影响,尤其是对 Methanosarcina spp. C-1 对醋酸菌甲烷生成途径有强烈的抑制作用。研究表明,C-1 的抑制靶标不同于著名的甲烷生成抑制剂 2-溴乙基磺酸盐,后者的靶标是甲烷菌的甲基辅酶 M 还原酶。此外,C-1 还具有抑制氯酚脱氯的副作用。虽然下一步开发工作还需要进行实地试验,但 C-1 可用于减少农业部门最大的甲烷排放源之一--水稻田的甲烷排放。
