Inoculation effect of cellulolytic and xylanolytic thermophiles on composting of cattle manure = 우분 퇴비화에 미치는 섬유질분해 고온균의 접종 효과

Abstract

The possibility of using the cellulolytic and xylanolytic thermophiles as microbial inoculants to facilitate composting of cattle manure containing sawdust as a bulking agent was investigated by measuring the changes in various physico-chemical and microbiolgical parameters. Inoculation of the thermophiles shorten the time required for the temperature to rise from 15 to 50℃ and was effective for maintaining high temperature during active composting stage. The higher population of thermophiles and mesophiles during the composting operations clearly reflected the effect of inoculation. In addition, from the data on many parameters including efficiency of carbon degradation, final/initial C/N ratio, redox potential, and activities of abiontic cellulase and phosphatase, it could be deduced that the inoculants may enhance the decomposition efficiency of solid substrates in the compost and thus shorten the period for the production of matured compost.
