| Research Abstract |
A microalga Botryococcus braunii produces large amounts of triterpene hydrocarbons, botryococcenes and methylsqualenes that are specific to the species. Those hydrocarbons are thought to be attractive as an alternative of petroleum. In this study, genes expressed in the alga were analyzed and some genes coding for new enzymes concerned with biosyntheses and metabolism of the hydrocarbons were identified. The mechanism for hydrocarbon production by the alga was found to be quite unique.
