“Development of new Gas-tO-1ipids bioprocess with acetogen and Oleaginous microorganism”
Fossil resources currently play dominant roles in energy production, but there are concerns about depletion of fossil resources and negative impacts on the global environment of CO2 discharged by fossil fuel consumption. To solve these problems, we aim to establish biorefinery technology using Labyrinthulean protist, genus Aurantiochytrium producing lipids which are usable in various industrial fields. I will introduce the construction of two-stage fermentation system comblning acetogenic bacteria and Aurantiochytrium sp. To produce useful lipids from CO2 gas.

“In Situ RNA Detection Tbward Elucidation of Functiona.1 Consortium”
RNase H-aSSisted RCA (RHa-RCA) has been developed to detect mRNA directly and to recognize functional genes. mRNA is an important molecule to recognize functional genes, therefore, this method will be applicable to elucidate the localization of functional genes in microbial community without detecting signal derived from genomic DNA. In order to visualize the ce11 itself, in this study, We developed RHa-RCA combined with fluorescence in situ hybridization. As a result, specific fluorescence to pyruvate-formate lyase activase gene in Streptococcus thermophilus was detected within harvested microbiome from yogurt. The results suggest that this method wi11 be useful tool to clarify microbiome by identifying the “owner” of functional gene.

“Biomass Utilization as Carbon Source for 2050”
Considering the whole renewable energy trend, cost reduction of photovoltaic is prominent and its introduction is expected only if battery system is available. Meanwhile, countries like China is introducing electric vehicles, which will accelerate the utilization and cost reduction of batteries. The role of biomass in this situation should be considered not in terms of power generation but in terms of carbon source. Possibility of biomass as carbon source in our country is discussed based on the energy statistics along with the scenario of zero emission of carbon dioxide in 2050.
