The methanogenic archaea need oxygen just like other living beings, but having evolved under anaerobic conditions, they developed the trick of getting their oxygen from their substrate rather than from the atmosphere. Thus they convert nitrates and sulphates into ammonia and hydrogen sulphide, and acetic acid, a carbohydrate, into methane, a hydrocarbon. When the slurry is applied to the soil, the soil microbes oxidise the ammonia into nitrate. The energy released in this process is used by the microbes for their own metabolism.and the nitrates are used by the plants. Yours A.D.Karve
