Production of Valuable Lipids from Underutilized Resources and Industrial Wastes by Biorefinery System

Abstract

For conservation of the global environment with the recycling of resources and energy, a novel sustainable biorefinery system has been developed to produce useful lipids such as polyunsaturated fatty acids, carotenoids, and hydrocarbons from marine macroalgae and thermal power generation exhaust gas. To maximize the productivity, a two-stage fermentation system was constructed using oleagenous Labyrinthulean protist, genus Auranthiochytrium, assimilating organic acids, which was tried to further functionalize by genome breeding technologies.
