Outline of Final Research Achievements

Microalgae such as green algae or diatoms are known to produce small amounts of linear hydrocarbons derived from fatty acids. The microalga, Botryococcus braunii also accumulates large amounts of unique linear alkenes that have a terminal double in their molecules. In this study, identification of genes concerned with biosynthesis of linear hydrocarbons in microalgae was tried. Genes coding for fatty acid photodecarboxylase (FAP), a new enzyme recently discovered from green microalgae were also expressed in B. braunii. FAP proteins of B. braunii could produce linear hydrocarbons from fatty acids such as palmitic acid or oleic acid.
