Optimization of light for growth, photosynthesis, and hydrocarbon production by the colonial microalga Botryococcus braunii BOT-22.
Optimization of the light conditions for biofuel production by the microalga Botryococcus braunii BOT-22 (race B) was performed using monochromatic red light. The lipid and sugar contents were approximately 40% and 20-30% of the cell dry weight, respectively, and about half of the lipids were liquid hydrocarbons. The half-saturation intensities for the production rate of lipids, hydrocarbons, a...
متن کاملIdentification of unique mechanisms for triterpene biosynthesis in Botryococcus braunii.
Botryococcene biosynthesis is thought to resemble that of squalene, a metabolite essential for sterol metabolism in all eukaryotes. Squalene arises from an initial condensation of two molecules of farnesyl diphosphate (FPP) to form presqualene diphosphate (PSPP), which then undergoes a reductive rearrangement to form squalene. In principle, botryococcene could arise from an alternative rearrang...
متن کاملProduction of biofuel by using micro algae (Botryococcus braunii)
Microalgae are photosynthetic, heterotrophic organisms that have an extraordinary potential for cultivation as energy crops. Microalgae are potential source of biomass, which may have great biodiversity and consequent variability in their biochemical composition (Satyanarayana et al., 2011). Under difficult agro-climatic conditions and are able to produce a wide range of commercially interestin...
متن کاملIsolation and Characterization of Cyclic C33 Botryococcenes and a Trimethylsqualene Isomer from Botryococcus braunii Race B.
Three cyclic C33 botryococcenes and one new trimethylsqualene isomer were isolated from the B race, Showa (Berkeley) strain of Botryococcus braunii, which is known to produce large amounts of isoprenoid hydrocarbons ranging in carbon number from 30 to 34. Their purity was determined by GC-MS, and structures were characterized by 1D and 2D NMR. One of these molecules, cyclic C33-1 botryococcene ...
متن کاملTranscriptome analysis of an oil-rich race B strain of Botryococcus braunii (BOT-70) by de novo assembly of 5'-end sequences of full-length cDNA clones.
Here the transcriptome of an oil-rich race B strain of Botryococcus braunii (BOT-70) was analyzed to mine genetic information useful in biofuel development. A full-length-enriched cDNA library was constructed via the oligo-capping method and the 5' ends of 11,904 randomly chosen cDNA clones were sequenced. Homology search using BLASTX identified candidate BOT-70 genes for majority of the reacti...
