It is known that A race B. braunii accumulates mainly the n-alkadiene and alkatriene [ 13], unlike B and L races of B. braunii that accumulate largely botryococcenes (or triterpenoids) and lycopadiene (or tetraterpenoids), respectively [ 14, 15].
Philips recently became the first entrant in the Energy Department's L Prize, a race to develop the first practical 60-watt LED equivalent to a standard light bulb.
17 is also the precursor for tetraterpenoid carotenoids, including lycopene, lutein, canthaxanthin and others isolated from race L and race B B. braunii strains [ 11, 66].
Race B and race L strains produce triterpenoids C30-C377 botryococcenes and methylated squalenes) or tetraterpenoids (C40 lycopadiene), respectively [ 10, 11].
Lycopadiene (46) is considered a biomarker for race L strains of B. braunii as there are no reports for the occurrence of this compound in race B strains [ 90].
The prominent liquid hydrocarbon trans,trans-lycopadiene (46, Figure 9) of race L strains of B. braunii is probably biosynthesized by reduction of an acyclic carotenoid such as 15- cis-phytoene (25) or lycopene (42) [ 10].
