Monod model was applied to describe the kinetic analysis of POME at different organic loading rates (OLR) in the range of 2.75-8.2 g TCOD per L per day. The hydraulic retention time (HRT) ranged between 8 and 24 days. The TCOD removal efficiency achieved was between 89.66% and 79.83%. The evaluated kinetic coefficients were: growth yield, YG (0.357 g VSS per g TCOD), specific biomass decay rate, b (0.07 per day), maximum specific biomass growth rate, μmax (0.27 per day), saturation constant for substrate, Ks (25.03 g TCOD per L), critical retention time, ΘC (3.72 day) and methane yield, Y CH4 (0.34 L CH4 per TCODremoved). Besides, new fermentative anaerobic bacteria isolated from POME were identified as Escherichia fergusonii, Enterobacter asburiae, Enterobacter cloacae, Desulfovibrio aerotolerans, Desulfobulbus propionicus, Fusobacterium nucleatum, Paenibacillus pabuli, Bacillus subtilis, Methanobacterium sp., Methanosaeta concilii, Methanofollis tationis, Methanosarcina mazei and Methanosarcina acetivorans using 16S rDNA. 2016-06-25T04:46:13Z 2016-06-25T04:46:13Z 2014 Article RSC Advances, vol.4 (110), 2014, pages 64659-64667 2046-2069 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/42202 10.1039/C4RA08483G en Royal Society of Chemistry
