Farnesol was incorporated into squalene as well as botryococcenes when the alcohol was fed to the culture of Botryococcus braunii B race strain. In in vitro experiments with a 10,000 x g supernatant of cell homogenate, squalene was synthesized from farnesyl diphosphate in the presence of NADPH or NADH, but botryococcenes were not synthesized under the same conditions. A 100,000 x g pelet fraction was able to phosphorylate farnesol to give its mono- and diphosphate esters in a CTP dependent manner.

The influence of metal elements on the biomedical activity of microalgal exopolysaccharides (EPS) remains underexplored. This study examined the antitumor properties of Botryococcus braunii EPS under high cobalt conditions and the role of exogenous 3-indole acetic acid (IAA) in enhancing its activity. Results showed that IAA mitigated cobalt-induced inhibition of B.

Botryococcus braunii is a colonial alga recognized for its slow growth but high hydrocarbon accumulation. Although using genetic engineering to increase the growth rate and hydrocarbon yield of B. braunii is desirable, the presence of an extracellular matrix (ECM) significantly hinders the emergence of a homogeneous colony from a single DNA-transformed cell.

The colonial green microalga Botryococcus braunii is well known for producing liquid hydrocarbons that can be utilized as biofuel feedstocks. B. braunii is taxonomically classified as a single species made up of three chemical races, A, B, and L, that are mainly distinguished by the hydrocarbons produced.
