Investigation Of Bio-Hydrogen Production Optimization From Synthetic And Real Wastes Using Pure And Mixed Cultures, Noha El-Sayed Nasr
Investigation Of Bio-Hydrogen Production Optimization From Synthetic And Real Wastes Using Pure And Mixed Cultures, Noha El-Sayed Nasr
Electronic Thesis and Dissertation Repository
Dark fermentative H2 production is an important route to renewable energy as it is based on a known technology and can utilize a wide range of available waste streams as substrate. However, more research is required to overcome the technical barriers to practical application. The aim of this study is to investigate different scenarios towards the optimization of fermentative H2 production from synthetic and real wastes using pure and mixed cultures. Lignocellulosic biomass, i.e. pretreated corn cobs and poplar wood hydrolysate were evaluated for H2 production using mixed anaerobic cultures and yields of 141 and 169 mL …
The Effects Of Furfural On Biological Hydrogen Production In Batch And Microbial Electrolysis Cell, Hyeongu Yeo
The Effects Of Furfural On Biological Hydrogen Production In Batch And Microbial Electrolysis Cell, Hyeongu Yeo
Electronic Thesis and Dissertation Repository
Furfural inhibits biohydrogen production and numerous studies has been carried out on detoxification of furfural to enhance biofuel production. Electrochemical detoxification of furfural is a new approach to remove furfural without the degradation of sugars. However, there is limited information on the effects of the degradation products of furfural on biohydrogen production in batch tests and the impact of furfural on anode-respiring bacteria (ARB) in microbial electrolysis cells (MECs). This study investigated the effect of furfural and its derivatives, furfuryl alcohol (FFA) and 2-furoic acid (FA), on biohydrogen production. The impact of furfural on hydrogen production in MECs was also …
Enhancement Of Biohydrogen Production From Co-Fermentation Of Glucose, Starch, And Cellulose, Medhavi Gupta
Enhancement Of Biohydrogen Production From Co-Fermentation Of Glucose, Starch, And Cellulose, Medhavi Gupta
Electronic Thesis and Dissertation Repository
The aim of this study was to assess the synergistic effects of co-fermentation of glucose, starch, and cellulose using anaerobic digester sludge (ADS) on the biohydrogen (H2) production and the associated microbial communities. At initial pH of 5.5 and mesophilic temperature of 37 ºC, the H2 yields were greater by an average of 27 ± 4% in all the different co-substrate conditions compared to the mono-substrate conditions, which affirmed that co-fermentation of different substrates improved the hydrogen potential. The sensitivity of mesophilic ADS to a temperature shock was also investigated. Unacclimatized mesophilic ADS responded well to a …
