Abstract

This investigation was carried out on the effects of compost-born thermophilic complex microbial consortium (TCMC) composed of Ureibacillus suwonensis (TB42), Geobacillus thermodenitrificans (TB62) and Bacillus licheniformis (TA65) on co-composting of dairy manure and sugarcane leaves. The study assessed the TCMC influence on physicochemical parameters and dissolved organic matter (DOM) properties. Compared to the control (CP), the inoculated pile (CPT) showed a longer thermophilic phase, a faster organic matter degradation, a better Kjeldahl nitrogen preservation as well as a greater aromaticity and stability of DOM. Consequently, the inoculation with TCMC agent was effective in reducing the loss of nitrogen and accelerating maturity of compost.
