Thermoacidophilic effective microbes (tEM) were used to enhance the composting process of lignocellulosic waste. Composting with tEM slightly reduced NH3 emission during the composting process while CH4, and CO2 patterns positively correspond to the rate of composting, with higher emissions in tEM treatment during 60d – 90d composting. Compost microbial evolution based metagenomic DNA sequencing and culture-based microbial enumeration indicate higher abundance and diversity of microbes in tEM treated groups especially at thermophilic temperatures. Chemical analysis showed higher rate of mineralization in tEM treated compost compared to control group while the heavy metal content was below the international threshold levels in both treatment and control. Moreover, germination index (Gi) and global germination index (GI) were higher in tEM treated compost compared to control group. The data is important for evaluating composting efficiency and quality of the final compost product.
