FISH analysis of microbial communities in a full-scale technology for biogas production.

The anaerobic digestion is a biological process that consists of four stages. At the final step of the biodegradation of the organics the most sensitive to the ambient factors group of microorganisms - the methanogens, produces biogas with main component methane. Common problems of these technologies are low biogas yield, production of biogas with low quality or situations in which the plant gets out of exploitation.
