  • Patent number: 8617857
    Abstract: The present invention relates to novel thraustochytrid-like microalgae having the ability to produce bio-oil, and a method of producing bio-oil using the same. The microalgae of the invention accumulate bio-oil at a high ratio in the cells when being cultured in glucose-containing medium, and thus can produce bio-oil in a high yield. Also, the microalgae can produce bio-oil using bean powder as a nitrogen source, and a product obtained by culturing edible bean powder as medium can be used as a raw material for producing food and feed. Also, the microalgae can produce bio-oil using non-food cellulosic biomass as a carbon source. Moreover, the use of non-food cellulosic biomass for production of bio-oil can overcome the factors limiting the development of bio-oil, including the unstable supply of food resources and an increase in the cost of raw materials, and can improve the commercial competitiveness of microbial fermentation oil.
