Sago Biomass as a Sustainable Source for Biohydrogen Production by Clostridium butyricum A1

Blog Article

Biohydrogen production from biomass is attracting many researchers in developing a renewable, clean and environmental friendly biofuel.The biohydrogen producer, Clostridium butyricum A1, was successfully isolated from landfill soil.This strain produced a biohydrogen yield of 1.90 mol H2/mol glucose with productivity of 170 mL/L/h using pure glucose as substrate.The Black Seed Oil highest cumulative biohydrogen collected after 24 h of fermentation was 2468 mL/L-medium.

Biohydrogen fermentation using sago hampas hydrolysate produced higher biohydrogen yield (2.65 mol H2/mol glucose) than sago pith residue (SPR) hydrolysate that produced 2.23 mol H2/mol glucose.A higher biohydrogen productivity of 1757 mL/L/h was obtained when using sago Dental Chewing Gums hampas hydrolysate compared to when using pure glucose that has the productivity of 170 mL/L/h.A comparable biohydrogen production was also obtained by C.

butyricum A1 when compared to C.butyricum EB6 that produced a biohydrogen yield of 2.50 mol H2/mol glucose using sago hampas hydrolysate as substrate.This study shows that the new isolate C.butyricum A1 together with the use of sago biomass as substrate is a promising technology for future biohydrogen production.
