Isolation and characterization of a novel strain Clostridium butyricum INET1 for fermentative hydrogen production
چکیده انگلیسی
A novel hydrogen-producing strain was isolated from gamma irradiated digested sludge and identified as Clostridium butyricum INET1. The fermentative hydrogen production performance of the newly isolated C. butyricum INET1 was characterized. Various carbon sources, including glucose, xylose, sucrose, lactose, starch and glycerol were used as substrate for hydrogen production. The operational conditions, including temperature, initial pH, substrate concentration and inoculation proportion were evaluated for their effects on hydrogen production, and the optimal condition was determined to be 35 °C, initial pH 7.0, 10 g/L glucose and 10% inoculation ratio. Cumulative hydrogen production of 218 mL/100 mL and hydrogen yield of 2.07 mol H2/mol hexose was obtained. The results showed that C. butyricum INET1 is capable of utilizing different substrates (glucose, xylose, sucrose, lactose, starch and glycerol) for efficient hydrogen production, which is a potential candidate for fermentative hydrogen production.
