Toxicity of the effluent to methanogen was analyzed.
并对其废水对产甲烷菌的毒性进行了分析。
Cellulose-decomposed bacteria and methanogen counting decreased, but the effect of alfalfa saponin on methanogen counting was more than on cellulose-decomposed bacteria counting.
添加苜蓿皂甙对细菌总数的影响不大但对纤维分解菌和产甲烷菌的生长和繁殖有抑制作用,对产甲烷菌的影响大于对纤维分解菌的影响。
Because methanogen is strict with its environment, especially with the occurrence of oxygen, trivial change should disturb the bacterial collects and make the number different from the reality.
考虑产甲烷菌对环境要求苛刻,微小变化均会改变菌群结构,导致测量结果与实际之间偏差明显;
