Physicochemical pretreatment of lignocellulosic corn fruit wastes (husk, shank, stalk) has been done. E. coli K12 growth, ORP kinetics, and H2 production were followed upon utilization of corn waste hydrolysates (CWH) separately and their mixture. During the bacterial log growth phase with the decrease of medium pH the readings of Pt electrode from positive to low negative values (~ –450±10 mV) were observed, with the yield ~ 0.75 mmol H2 /L and 0.29 bacterial cell dry weight g/L biomass in CWH based medium. Meat (chicken wastes) broth supplementation ~2 fold enhanced both E. coli biomass formation and H2 production on CWH mixture.
