3-2-1　セルロースの急速熱分解糖化と糖化物の乳酸発酵性

抄録

It is known that fast pyrolysis of cellulose produces a large amount of levoglucosan, which can be saccharified under mild conditions. This fast-pyrolysis-base saccharification may apply for the production of polylactic acid (a bioplastic) via lactic acid fermentation. However, the pyrolysis of cellulose generally gives by-products, which may inhibit the fermentation. In this study, we investigated the lactic acid fermentability of the sugar solution as prepared via the fast pyrolysis of cellulose under the irradiation of IR. As a result, lactic acid fermentation proceeded for a low concentration sugar solution (11.1 g/L), but not for the high concentration (22.2 g/L). Then, we investigated the inhibitors and the removal way to improve the fermentability for the high concentration sugar solution.
