The production of hydrocarbons by Botryococcus braunii

As Tornabene^1,2 has already discussed in this and in an earlier volume, many microorganisms — photosynthetic or not — are capable of producing hydrocarbons which can account for up to 1% of the dry mass (see tables I–V in ref. 1). At the moment, it seems that there is only 1 exception described in the literature which produces a larger proportion: the unicellular green alga Botryococcus braunii.
