The increasing water crisis makes fresh water a valuable resource, which must be used wisely. However, with growing population and inefficient waste treatment systems, the amount of wastewater dispelled in rivers is increasing abominably. Utilizing this freely available waste-water along with biodiesel industry waste- crude glycerol for bio-hydrogen production is being reported here. The bacterial cultures of Bacillus thuringiensis strain EGU45 and Bacillus amyloliquefaciens strain CD16 produced2.4-3.0 L H2/day/L feed during a 60 days continuous culture system at hydraulic retention time of 2 days. An average H2 yield of 100-120 L/L CG was reported by the two strains. Recycling of the effluent by up to 25% resulted in up to 94% H2 production compared to control.
