| Research Abstract |
Under the conditions equivalent to the fluctuating environment at the deep end of the Osaka Bay, experiment on macro algae production was made, and growth rate and environmental recovery potential were determined. Also, procedure for seeding and collection in the actual sea was discussed. When waste water from factories are mixed with the sea water, the macro algae is effective for waste water treatment. This marine biomass can be made into slurry by hydrothermal pretreatment. A group of microorganism was obtained which produces ethanol using alginic acid as the only substrate. The fermentation residue was gasified in the supercritical water, and the effect of salt was elucidated. The system design based on these findings showed that energy production is possible using the macro algae although its economic feasibility is low.
