Dear List,

Although the microbes responsible for making biogas work under anaerobic
conditions, they do use oxygen, which they extract from the feedstock. Thus,
when you feed them with a carbohydrate, they give back to you methane, a
hydrocarbon, using the oxygen from the carbohydrate for driving their own
metabolism. The rate of biogas production is much higher when you use a
cabohydrate rich substrate rather than dung. In fact the biogas producing
organisms even convert carbon dioxide into methane. This gave me the idea of
providing a biogas plant with a chemical rich in oxygen and to see if the
biogas production is accelerated. Some of the substances classically used as
oxygen donors in various chemical reactions are potassium permanganate,
potassium dichromate, potassium chlorate or many of the peroxides, nitrates
and sulphates. Does anyone have ideas or comments on this theme?
Yours
A.D.Karve
