Due to the global warming, fuel security and economics, reusable fuels for transportation have been urgently needed. Marine biomass such as macroalgae has been attracted offering a huge amont of energy substrate for biofuel production. There has been remarkable interest in conversion of macroalgae into fuels in Korea lately. At the same time, interest in butanol
fermentation using solventogenic clostridium also has been renewed due to high demands of alternative fuels and disadvantages of ethanol.We examined butanol fermentation by Clostridium beijerinckii NCIMB 8052 using Laminaria japonica (kelps) as substrates. In order to increase sugars content of the hydrolysates, pretreatment with acid or base was applied before
enzymatic hydrolysis using laminarinase, alginate lyase and cellulase. The maximum amount of sugars (9 g/L) was produced in 0.5 M H2SO4 in acid pretreatment step, followed by enzyme treatment. Fermentation test was prepared in the hydrolysate of 25 g/L and 50 g/L kelp, using different hydrolysis process. Both growth and butanol production have seen in the most of hydrolysate cultures but it was noticeable that water soluble material without any pretreatment was found to be a good culture medium for clostridium. Fermentation of major sugar componets (alginate, lamininarin, D-mannitol, fucoidan, etc) in macroalgea hydrolysate were also tested at the concentration of 10 g/L and 30 g/L in 96 well cell culture test system.
