Using solid-state cross-polarization-magic-angle-spinning (CPMAS) C and N nuclear magnetic resonance (NMR) and 2-D double cross polarization (DCP) MAS N C NMR techniques, microbially degraded Botryococcus braunii was analyzed to study the chemical nature of organic nitrogen in the algal residue. The amide linkage, as found in protein, was observed as the major nitrogen component in 201-day-old ...

Growth of Botryococcus braunii (race 'A') and production of its constituents viz, hydrocarbon, carbohydrate, fatty acid, and carotenoids were influenced by different levels of salinity. Under salinity at 34 mM and 85 mM, 1.7-2.25-fold increase in the relative proportion of palmitic acid and two fold increase in oleic acid were observed. A twofold increase in carotenoid content was noticed at 85...

The green colonial microalga, Botryococcus braunii is well known for its high lipid content and has already been proposed as a renewable energy source for various aquaculture and biotechnological applications. However, due to its slow growth rate compared with other microalgae, B. braunii has not yet been used in mass culture to produce more biomass. Therefore, in this study we tested different...

The green microalga Botryococcus braunii produces large amounts of liquid hydrocarbons and is classified into three races, depending on the type of the hydrocarbon produced. The B race produces two types of triterpenoid hydrocarbons, squalene and botryococcene, both of which are putative condensation products of farnesyl diphosphate. In an attempt to better understand the regulation involved in...

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...
