英文要約Title : Development of Production Technologies for Biojet fuels / Pilot scale test on once through production process / Development of once through production process of biojet fuel using Hyper-Growth Botryococcus braunii (FY2017-2020)FY2018 Annual Report

Hyper-Growth Botryococcus braunii, HGBb, is phototrophic algae strain improved without using genetic recombination technique, and characterized by unprecedentedly high speed in growth rate and high percentage of hydrocarbon concentration.
This four years long research and development project has three objectives. The first is to conduct outdoor cultivation of HGBb, which method was developed in the past project as low cost and low energy integrated process from cultivation to harvesting, at Thailand where tropical and stable climate can be expected. From there, we target to establish methodology and integrate the processes between cultivation, yield, drying and conversion for bio-crude oil extracted from HGBb to produce bio jet fuel, conforming to ASTM D7566. The second is to seek and identify for the influential factor which improves HGBb's strain further suited to mass cultivation and oil production. The third is to establish a method for environmental risk assessment upon mass outdoor cultivation of HGBb, especially in regards to small fish and microbes in the surrounding environment.
We have made progresses in achieving these objectives in FY2018. We continued implementation of pilot-scale cultivation test facility on idle land at Saraburi, Thailand. The 1 hectare scale cultivation pond was constructed in FY2018. Each pond utilized low cost pond construction method developed in the past project. Initial cultivation had undergone prior to the local rain season of FY2018, and we succeeded in outdoor cultivation of HGBb in the pilot-scale cultivation test facility up to scale of 3,000 square meters.
We also continued successful outdoor cultivation of HGBb in Japan. The extracted oil from the cultivated HGBb underwent jet conversion, and the output neat bio-jet fuel was sent to ASTM designated testing facility to enter ASTM qualification tests.
For improvement of HGBb strain, utilizing the improved method to efficiently obtain long-chained DNA of HGBb established in FY2017, genetic information related to characterization of HGBb's oil production and photosynthesis was obtained.
    Three microbes (Daphnia, paramecium, and rotifers) were selected and observed their predatory activity against HGBb. Due to that these microbes were smaller than HGBb, they showed no predation against HGBb. For small fish, killifish was selected and showed aggressive predation and it confirmed that intake of HGBb showed no effect on their survival rate.
The FY2018 progress is to be carried on to FY2019 for further outdoor mass cultivation at Thailand, which would anticipate cultivation area more than 1 hectare, to establish pilot scale integrated process from HGBb cultivation to supplying ASTM conforming bio jet fuel.
