To utilize wastes and residues sustainably excellently, there is a need to fend for efficient methods resources biogas production. Use of poultry waste production represents one the most important routes toward reaching global renewable energy targets. The current study involves microbial pretreatment chicken feather waste, followed by its co-digestion with rice husk green grocery in batch continuous reactors, respectively. Microbial feathers keratinase secreting Pseudomonas aeruginosa was an effective eco-friendly approach make recalcitrant structure available as raw substrate also addressed enhancement stability anaerobic digestion co-digestion. Results demonstrated that increased percentage increase yield 1.1% microbialy pretreated compared mono-digestion (non-pretreated feathers) fermentation. highest obtained reactor having feathers. hydrolysate fermentation mode has enhanced average (chicken waste) and, therefore, improve efficiency overall process.
