Simultaneous Biohydrogen and Bioethanol Production from Anaerobic Fermentation with Immobilized Sludge
The effects of organic loading rates (OLRs) on fermentative productions of hydrogen and ethanol were investigated in a continuous stirred tank reactor (CSTR) with attached sludge using molasses as substrate. The CSTR reactor with attached sludge was operated under different OLRs, ranging from 8 to 24 kg/m(3)·d. The H(2) and ethanol production rate essentially increased with increasing OLR. The ...
متن کاملBiohydrogen production from oil palm frond juice and sewage sludge by a metabolically engineered Escherichia coli strain
Biohydrogen is considered a promising and environmentally friendly energy source. Escherichia coli BW25113 hyaB hybC hycA fdoG frdc ldhA aceE has been previously engineered for elevated biohydrogen production from glucose. In this study, we show that this strain can also use biomass from oil palm frond (OPF) juice and sewage sludge as substrates. Substrate improvement was accomplished when hydr...
متن کاملInverted phase fermentation as a pretreatment for anaerobic digestion of cattle manure and sewage sludge.
The aim of this research study was to analyse the effect of applying inverted phase fermentation (IPF) prior to the anaerobic digestion of cattle manure and sewage sludge. IPF promotes the endogenous bacteria present in waste and hence enzymatic hydrolysis, producing a solid-liquid separation. The clarified bottom layer or liquid phase (LP, 70% volume in manure and 65% in sludge), and the thick...
متن کاملOutlook of biohydrogen production from lignocellulosic feedstock using dark fermentation – a review
Hydrogen becomes a promising alternative energy carrier to fossil fuels since it is clean, renewable, contains high energy content and does not contribute to greenhouse effect. Therefore, using cheap or renewable resources, such as lignocellulosic materials, as the feedstock for hydrogen production, in particular, dark fermentative hydrogen production has a great potential to give major contrib...
