Abstract

Problem statement: The aim of this study was mainly focused on the evolution of microbial biomasses C and N during the composting of municipal solid wastes. Approach: The carbon and the nitrogen of the microbial biomass (BC and BN) were studied using the fumigation-extraction method. Results: The dynamics of the BC/BN ratio, index of the chemical composition of the whole microbial population suggested a shift in the composition of microbial populations during the process from prevailing bacteria and actinomycetes to prevailing fungi. Conclusion/Recommendations: Microbial characterization of composting is of importance for the optimization of the process and the quality of the end product.
