Changes in Potential Pathogens During Temperature-controlled Pig Manure Composting Process

With the development of intensive livestock and poultry breeding, problems associated with pathogenic microorganisms in animal manure are becoming more obvious. The bacteria pig may cause zoonotic transmission, which not only hinder healthy industry, but also harm people's health. In this study, diversity abundance potential pathogens composting process under three temperature-controlled treatments (high-temperature group, medium-temperature group low-temperature group) were analyzed based on high-throughput sequencing technology. A total 13 identified process, among Enterococcus faecalis Agrobacterium vitis accounted for largest proportions (12%). Under different treatments, abundances Pseudomonas stutzeri Acinetobacter baumannii changed most obviously. Moreover, high-temperature treatment significantly lower than those treatment, indicating that high temperature condition could effectively remove inhibit growth reproduction pathogens.
