Abstract Reduction of dissimilatory Fe(Ⅲ) by humic-reducing microorganisms (HRMs) from different composts was conducted. Results showed that the capacity for reduction of dissimilatory Fe(Ⅲ) by HRMs was ranked in the order protein-rich compost > cellulose-rich compost > lignin-rich compost. The result of correlation showed that Leucobacter、Clostridium sensu stricto and Sporosarcina were significantly associated with the Fe(Ⅲ) reduction. It was indicated that dissolved organic nitrogen was the primary micro-enviromental factors significantly driving the variation of these key HRMs by Redundancy analyses (RDA). Finally, based on the relationship between the mico-enviromental factors and HRMs, this work proposed a regulating method to enhance the growth of the key HRMs during composting. This study not only investigated the influencial factors of HRMs in compost deeply, but also had ecological significant in the study of waste biogeochemical process.
