The effects of the initial pH (5.0-6.5), sucrose concentration (13-43 mM) and repeated batch cultivation on biohydrogen production from sucrose were investigated using anaerobic sludge from a palm oil mill effluent treatment plant. The cumulative hydrogen production results were fitted into a modified Gompertz equation in order to find the optimum operational conditions. The optimal hydrogen yield (2.8 molH2/molhexose) was obtained at an initial pH of 5.5 and sucrose concentration of 13 mM after fifteen cycles of repeated batch. Enriched granular activated carbon (GAC)-immobilised cells from the repeated batch cultivation were used as the immobilised seed culture for anaerobic fermentation of sucrose into hydrogen in continuous operation using a fluidised-bed column reactor (FBCR). The maximum hydrogen production rate (HPR) was found to be 2.7 mmolH2/L/h and the hydrogen yield peaked at 2.8 molH2/molhexose-consumed after a hydraulic retention time of 12 h. The main soluble metabolites were identified as acetic acid, butyric acid and ethanol. The hydrogen content ranged from 48 to 50% of the total biogas. 2016-04-05T02:07:53Z 2016-04-05T02:07:53Z 2016-02-01 Article Process Biochemistry, vol. 51 (2), 2016, pages 297-307 1359-5113 (Print) 1873-3298 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41255 doi:10.1016/j.procbio.2015.11.031 en Elsevier BV
