Process Performance and Functional Microbial Community in the Anaerobic Digestion of Chicken Manure: A Review

Anaerobic digestion is one of the most widely used treatment methods for animal manure. Chicken manure has high methane production potential and thus a suitable substrate biogas plants. However, nitrogen content inhibits metabolism anaerobic microorganisms hinders from chicken Enhancing performance indeed long-standing challenge. This review presents new insights into maintaining methanogens’ activities, decomposition acetate, dynamics methanogenic pathways under ammonia stress. also analyzed possible strategies alleviating inhibition effects, including supplementing trace elements, co-digestion with nitrogen-less materials, in-situ removal, long adaptation consortia to The obtained in this paper may provide helpful information better understanding technology other nitrogen-rich waste wastewater.
