Recently, the biosynthetic pathway for lycopadiene, a C40 tetraterpenoid hydrocarbon, was deciphered from the L race of Botryococcus braunii, an alga that produces hydrocarbon oils capable of being converted into combustible fuels. The lycopadiene pathway is initiated by the squalene synthase (SS)-like enzyme lycopaoctaene synthase (LOS), which catalyzes the head-to-head condensation of two C20...

A series of C30 branched isoprenoid hydrocarbons with a cyclobotryococcane skeleton were identified in the Florida Coastal Everglades Ecosystem. Nine such C30 alkenes were detected and identified as five-membered ring monocyclic hydrocarbons with an identical parent structure of 7,11-cyclobotryococcane based on their mass spectra and hydrogenation behavior. Previous reports have suggested Botry...

Botryococcus braunii CCAP 807/2 has been studied intensively for biofuel production due to its high hydrocarbon content. This strain is also capable of producing value carotenoids. The aim the study was analyse carotenoid B.braunii under different growing conditions, first, by using media and light intensities in indoors, next, examine composition between green, intermediately pigmented red B. ...

Highlight Research The methanolic extracts of salinaand B. braunii contained alkaloids, steroids, triterpenoids, flavonoids, and saponins. Chlorophyll a, chlorophyll b, carotenoids were most abundant in the ethyl acetate braunii. maximum total phenolic content was observed n-hexane extract salina(61.28 mg GAE/g sample) (46.94 sample). exhibited highest antioxidant activity, whereas saponins met...
