High-rate anaerobic digestion of palm oil mill effluent in an upflow anaerobic sludge-fixed film bioreactor
Abstract The upflow anaerobic sludge-fixed film (UASFF) reactor is one of the granular sludge bioreactors that are used for the rapid biotransformation of organic matter to methane with the help ofExpand
Bioconversion of synthesis gas to second generation biofuels: A review
The ever increasing concerns over fluctuating price of oil and the possible future supply constrains have reinforced the need for alternative fuel resources. Use of synthesis gas (syngas) to generateExpand
Ethanol and acetate production from synthesis gas via fermentation processes using anaerobic bacterium
Abstract Synthesis gas was used to produce ethanol and acetate via fermentation processes. A strict autotrophic bacterium, Clostridium ljungdahlii , was grown on syngas to investigate production ofExpand
Anaerobic co-digestion of animal manures and lignocellulosic residues as a potent approach for sustainable biogas production
Anaerobic digestion is a versatile biotechnology for conversion of organic wastes to valuable biogas. Anaerobic digestion of manure is making the most of it, as the process allows simultaneousExpand
Ethanol fermentation in an immobilized cell reactor using Saccharomyces cerevisiae.
The present research has shown that high sugar concentration (150 g/l) in the ICR column was successfully converted to ethanol, and the proposed model can be used to design a lager scale I CR column for production of high ethanol concentration. Expand

Process modeling and analysis of palm oil mill effluent treatment in an up-flow anaerobic sludge fixed film bioreactor using response surface methodology (RSM).
The present study provides valuable information about interrelations of quality and process parameters at different values of the operating variables in a UASFF reactor treating palm oil mill effluent. Expand
Performance of a three-stage aerobic RBC reactor in food canning wastewater treatment
Abstract Biological treatment using attached growth in a three-stage lab-scale rotating biological contactor (RBC) was implemented for wastewater from food cannery industries. The wastewaterExpand
Clostridium aceticum—A potential organism in catalyzing carbon monoxide to acetic acid: Application of response surface methodology
Abstract Carbon monoxide is a poisonous gas that results from the automobile emission, gasification of biomass and sewage sludge. The conversion of carbon monoxide as the gaseous substrate to aceticExpand
Kinetic evaluation of palm oil mill effluent digestion in a high rate up-flow anaerobic sludge fixed film bioreactor
Abstract A kinetic study of the anaerobic digestion process of palm oil mill effluent (POME) was carried out in a laboratory-scale up-flow anaerobic sludge fixed film (UASFF) bioreactor at mesophilicExpand
