Effect of inoculation with multiple composite microorganisms on characteristics of humic fractions and bacterial community structure during biogas residue and livestock manure co-composting

摘要

BACKGROUND: It is necessary to inoculate microbes in the composting of special materials. Biogas residue (BR) is rich in refractory lignocellulose. To improve humification processes of BR composting, composite microorganisms (CMs), with multiple functions, were added to the mixture of BR and animal manure.
