Abstract: The hydrogen producing organisms such as Escherichia coli (E.Coli), Enterobacter cloacae, Hafnia alvei, Citrobacter freundii, Serratia marcescens and Clostridium acetobutylicum strains were isolated from the sludge of biogas plant. The hydrogen producing efficiency of isolated organisms from kitchen waste were examined under anaerobic conditions. Lab scale studies were conducted under controlled and ambient temperature conditions, both in the presence and absence of bacteria. Maximum hydrogen production was found in the experiment with the Clostridium acetobutylicum. The hydrogen production in the reactor with Clostridium acetobutylicum was estimated as 179.59 mL/kg TS/day in ambient temperature condition and 185.92 mL/kg TS/day in controlled temperature condition.
Keywords: anaerobic digestion; kitchen waste; solid phase digestion; biohydrogen; biogas sludge; hydrogen production; waste management.
