Hydrogen production from palm oil mill effluentPOME by Thermoanaerobacterium thermosaccharolyticum PSU-2 wasinvestigated both in batch and continuous reactors using anaerobic sequencingbatch reactor ASBR and continuous stirred tank reactor CSTR. The hydrogenproduction determined from batch experiment of POME at an inoculum size of 0%,10%, 20% and 30% v-v was 161, 201, 246 and 296 mL H2-g-COD withCOD removal efficiency of 21%, 23%, 23% and 23%, respectively. Continuoushydrogen production was start-up with 30% v-v inoculum in both ASBR and CSTRreactors and more than 30% COD removal could be obtained at HRT of 4 days,corresponding to OLR of 11.3 g COD- L┬Ěday.Similar hydrogen production rates of 2.05 and2.16 LH2-L. daywere obtained from ASBR and CSTR, respectively. COD removal efficiency of ASBRwas 37.7%, while it was 44.8% for CSTR. However, ASBR was stable in term ofalkalinity, while the CSTR was stable in term of hydrogen production, solublemetabolites concentration and alkalinity. Therefore, the CSTR was found to bemore stable in hydrogen production than ASBR under the same OLR.
