title: Effect of Substrate on Identification of Microbial Communities in Poultry Carcass Composting and Microorganisms Associated with Poultry Carcass Decomposition.
abstract: Three composting systems, which consisted of different ratios of chicken manure, sawdust, and poultry carcasses, were used to investigate the effect of substrate on the identification of microbial communities and microorganisms associated with poultry carcass decomposition by characterizing the microbial communities and physicochemical parameters. The physicochemical and Miseq Illumina sequencing results showed the composition of substrate had a significant effect on the identification and metabolic capabilities of microbial communities in decomposting process. Poultry carcasses might be the potential driver for the identification of bacterial communities in poultry carcass composting, whereas the initial C/N ratio may mainly contribute to the diversity of fungal communities and the similar dominant microbial communities in treatments. Poultry carcasses and initial C/N ratio could respectively affect the composition and abundance of microorganisms associated with the decomposition of poultry carcasses. Understanding the potential composting driver could allow development of an efficient carcass degradation system.
