Novel approach of Biohydrogen production from Biodiesel industry waste (crude-glycerol) using co-culture system Abstract Number: #600188

摘要

In a view to uplift the biodiesel industry as a major energy carrier, new approach of utilizing generated waste crude glycerol (CG) needs to be explored. Bioconversion of CG to hydrogen is a widely explored approach in comparison to the production of other value-added products. Biohydrogen production can be carried out using renewable and sustainable technologies with combined waste treatment in comparison to chemical methods associated with consumption of fossil fuels. The properties of eggshells (EGS) as neutralizing and immobilizing agent were investigated for hydrogen (H2) production using CG by co-culture system. Eggshells of different sizes and concentrations were used during batch and repeated-batch fermentation. For batch and repeated-batch fermentations, the maximum H_2 production (36.53 ±0.53 and 41.16 ±0.95 mmol/L, respectively) were obtained with the EGS size of 33 um
