“Biodiesel production from microalga Nannochloropsis”

Nannochloropsis is a genus of marine microalga that can produce high quantities of lipids in the form of triacylglycerol, which has recently attracted attentions as a potential feedstock for biofuel production. In order to achieve the practical use of algal biodiesel,　we are investigating optimal culturing conditions and genome-editing tools for the development of improved Nannochloropsis. In this lecture, I’d like to introduce Nannochloropsis and our study of the optimization of culturing condition.

“Reaction rate analysis for supercritical water treatment of guaiacol”

The effect of residence time in the range of 15 to 90 s on supercritical water gasification of guaiacol as model compound of lignin was studied at temperature of 600 ℃, pressure 25 MPa, and fixed concentration of guaiacol of 0.5 wt%. The result in total organic carbon decreased while char product increased with residence time. However, the residence time did not affect carbon gasification efficiency.
