The main objective of this study is to investigate the potentiality of cellulase producing isolates, Bacillus licheniformis 1-1v and Bacillus sonorensis 7-1v, as microbial additives on composting of rice straw materials. Different pyramid shape piles were constructed, and each contained 80 kg of rice straw and 288 kg of cattle manure, with/without 5 kg of feldspar supplementation (, w/w). C/N ratio was adjusted to before microbial inoculation. |
