What is low in your case and low as compared to what?

Subodh Kumar

Biomethane yield of mono digestion of raw rice straw goes up to 200-250 mL/gVS . In that case after co-digestion of rice straw and algae, biomethane yield should be improved.

It seems there is something missing in the information/knowledge about anaerobic digestion process. Please go through these and I hope you will get a better insight in the process.

Book Microbiology of the biogas process

Chapter Protocol for Start-Up and Operation of CSTR Biogas Processes

Thanks for your kind suggestions.
