“Acetic acid production from biomass by hydrothermal reaction”

A microorganism that produces oil from acetic acid as a biodiesel candidate has been discovered. It has also been found that acetic acid can be produced by hydrothermal treatment of hydrous waste biomass. In this study, we used glucose to estimate the optimal conditions for the hydrothermal reaction, and to investigate the carbon yield and intermediates of acetic acid under each condition to confirm the production characteristics of acetic acid. The reactor was a continuous type reactor with a temperature of 300 °C and a pressure of 8.6 MPa, using aqueous hydrogen peroxide as the oxidizer. The amount of oxygen required for the complete combustion of glucose was set at 100%, and the amount of oxygen given and the residence time were varied to examine the yield of acetic acid and other carbons. From the data obtained, the reaction characteristics of acetic acid were evaluated.

“Molecular breeding of yeast for the efficient production of fermented products from lignocellulosic biomass”

In order to create a recycling-oriented society, establishment of fermentation technology for producing useful substances such as ethanol, which has a large effect of reducing CO2 emissions, from lignocellulosic biomass, a renewable resource, is expected. Yeasts with high fermentation ability are widely used for fermentation production from glucose, but cannot utilize hemicellulose-derived xylose. In addition, in the fermentation process, high fermentability is required for yeast even under severe stressed condition. In this seminar, I will introduce some related topics regarding breeding development of yeasts with these useful traits.
