Summary

This basic research was carried out on bio-ethanol derived from cellulosic waste (rice straw).  In view of the fact that rice straw is incorporated into the soil after harvesting the grains to increase mineral soil content, we examined the option of using high pressure pretreatment which does not involve chemical treatment, thus allowing residues from bio-ethanol production to be returned to the soil as a liquid fertilizer.  Results from this study showed that i) high-pressure treatment enhanced the saccharification of rice straw and ii) soil containing residues from bio-ethanol production did not inhibit the growth of Japanese mustard spinach planted from seed.

Key words: cellulosic waste (rice straw), high-pressure treatment, soil containing residues, bio-ethanol production
