摘要：The aim of this research was to find out the effect of substrate concentrations (COD) of vinasse and the length of fermentation time to bio-hydrogen gas production using agent of fermentation photosynthetic bacteria,Rhodobium marinum.The production of bio-hydrogen was examined by varying COD of vinasse (10,000;20,000;30,000;40,000;50,000 mg COD/L) at certain fermentation time in the third,sixth and ninth day.The highest Hydrogen gas was obtained at ninth day of fermentation (82.66±18.6 mL).The highest Hydrogen Production Rate (HPR) and COD removal rate were obtained at concentration 50,000 mg COD/L,namely 109.98 mL H2/L/d and 1437.66 mg COD/L/d,respectively.Thus it can be concluded,the concentration of substrates (COD) from vinasse and the length of fermentation time have an effect on production of bio-hydrogen gas usingm.
