Palm oil mill effluent (POME) contains large quantities of organic matter in the form total suspended solids (TSS), volatile (VSS), (TS), and grease (O & G) that increase biochemical oxygen demand (BOD) chemical (COD) POME if left untreated. The main aim present study was to investigate ability bacterial strains either pure (individually) or mixed (combinations), degrade metabolize load from palm effluent. Sequencing 16S rRNA isolates suggests they were identified as Micrococcus luteus 101 PB, Stenotrophomonas maltophilia 102 Bacillus cereus 103 Providencia vermicola 104 Klebsiella pneumoniae 105 PB subtilis 106 PB. use cultures showed more extensive removal (COD BOD) than single cultures. Mixed found reduce pollutant dynamically. Thus, C1 (Bacillus PB) most effective combination for biological treatment technology having highest COD BOD reduction rate. produced degradative activity reducing (90.64 %) (93.11 %). indigenous microbial observed possess potential components whereas resulted degradation This culture bacteria can be used bioremediation environment contaminated with polluted wastewaters. study, however, indicates prospect isolating microorganisms biotreatment POME.
