Enhancing the compost maturation of swine manure and rice straw by applying bioaugmentation

Abstract Microorganisms capable of decomposing cellulose, xylan, starch and protein were individually isolated from swine manure compost and soil in this study. The correlations with pH, carbon source concentration, C/N ratio and enzyme activity among these isolated microorganisms were also investig...
