MICROBIAL SUCCESSION IN CO-COMPOSTING OF CHIPPED-GROUND OIL PALM FROND AND PALM OIL MILL EFFLUENT

Author(s): MOHD NAJIB AHMAD*; SITI RAMLAH AHMAD ALI* and MOHD ALI HASSAN**

Succession and phylogenetic profile of microbial communities during co-composting of chippedground oil palm frond (CG-OPF) and palm oil mill effluent (POME) were studied by applying polymerase chain reaction-denaturant gel gradient electrophoresis (PCR-DGGE) analysis. The results indicated that the dominant microbial community detected was γ-Probacteria such as Pseudomonas sp. at almost throughout the composting process. Whilst Bacillales such as Bacillus psychrodurans were found toward the end of the composting process. Bacteroidetes such as Pedobacter solani were detected at the final stage of composting. This study contributed to a better understanding of microbial shifting and functioning throughout CG-OPF composting. Therefore, PCR-DGGE is recommended to be used as a tool to identify potential microbes that can contribute to a better performance of composting process.
