The archaea contain many organisms of extreme environments , such as hydrothermal vents , hot springs , saline sediments , volcanic craters and boiling muds . they include methane - generating organ - isms ( methanogens ) , sulfate reducers , and extremophiles 古细菌包括许多生长在极端环境中的有机体，如高热温泉口，高盐沉积地区，火山喷发处，沸腾的岩浆中等的生物有机体，还包括产甲烷菌等。
Based on these and other considerations , some scientists have proposed that methanogens living on geologically derived hydrogen might form the base of underground microbial ecosystems on mars and on jupiter ' s ice - covered moon , europa 基于前述及若干理由，有些科学家便提出，在火星以及被冰层覆盖的木星卫星木卫二上，以地质活动所产生的氢气为生的产甲烷菌，可能会形成地下细菌生态系的主体。
Abstract : inhibition mechanisms of sulphate reduction to methane - producing bacteria ( mpb ) in the process of anaerobic digestion of high - sulphate - content wastewater were described in this paper . they were described mainly by the competition between sulphate - reducing bacteria ( srb ) and methane - producing bacteria ( mpb ) , and inhibition of sulfide produced by the microbial reduction of sulphate , meanwhile , the present anaerobic digestion technologies for the high - sulphate - content wastewater treatment were introduced 文摘:本文通过硫酸盐还原菌和产甲烷菌的竞争、硫化物对产甲烷菌的毒害二方面，论述了在高硫酸盐有机废水厌氧处理过程中，硫酸盐还原作用对产甲烷菌活性的抑制机理，同时，介绍了当前高硫酸盐有机废水的厌氧处理工艺。
Recycling the collected leachate to landfill can raise the ratio of containing water of garbage , and increase the humidity of garbage , and improve the activity of microbial in garbage , and improve the rate of producing methane , accelerate the decomposition of organic and shorten the stabilization process of landfill 将渗滤液收集，回灌到填埋场可以提高垃圾层的含水率，增加垃圾的湿度，增加垃圾中微生物的活性，加速产甲烷的速率和垃圾中污染物溶出及有机物的分解，缩短填埋场垃圾的稳定化进程。
