Summary: | There is an increased interest in composting as
an effective means of handling large amounts of organic
wastes generated by oil palm industries in Malaysia.
However, very few studies have been conducted to develop
an effective composting process using the multi-enzymatic
system. This study demonstrates an effective composting
process of EFB (empty fruit bunch) with POME (palm oil
mill effluent), using the optimized process parameters and
compatible multi-enzymatic fungal system. A higher
decrease (3 %) of organic matter was achieved in the
fungal treated system, almost double that of the control
(without inoculum). The lowest C/N ratio and soluble
protein content recorded were about 17 and 128.82 g/kg,
respectively. The maximum germination index obtained
was 116 % at day 50 of treatment, which is considered high
compared to the control (uninoculated). Furthermore, the
maximum activity of ligninase enzyme was found to be
25.95 U/g and the highest cellulase activity was recorded at
0.975 U/g. |
