Production of biofuel by using micro algae (Botryococcus braunii)
نویسنده
چکیده
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 interesting byproducts such as fats, oils, sugars and functional bioactive compounds (Erika C Francisco et al., 2010).

Seawater-Cultured Botryococcus braunii for Efficient Hydrocarbon Extraction
UNLABELLED As a potential source of biofuel, the green colonial microalga Botryococcus braunii produces large amounts of hydrocarbons that are accumulated in the extracellular matrix. Generally, pretreatment such as drying or heating of wet algae is needed for sufficient recoveries of hydrocarbons from B. braunii using organic solvents. In this study, the Showa strain of B. braunii was cultured...
متن کاملTranscriptomic analysis of a moderately growing subisolate Botryococcus braunii 779 (Chlorophyta) in response to nitrogen deprivation
BACKGROUND The colonial microalga Botryococcus braunii has been brought to people's attention for its conspicuous ability to accumulate a variety of lipids including hydrocarbons. B. braunii strains are classified into 3 races based on the types of hydrocarbons. A and B races are known to accumulate high level of lipids. However, their extreme slow growth rate has impeded its application for re...
متن کاملA novel alphaproteobacterial ectosymbiont promotes the growth of the hydrocarbon-rich green alga Botryococcus braunii
Botryococcus braunii is a colony-forming green alga that accumulates large amounts of liquid hydrocarbons within the colony. The utilization of B. braunii for biofuel production is however hindered by its low biomass productivity. Here we describe a novel bacterial ectosymbiont (BOTRYCO-2) that confers higher biomass productivity to B. braunii. 16S rDNA analysis indicated that the sequence of B...
متن کاملUtilization of Algal Consortium to Produce Biofuels and Byproducts For Reducing Pollution load
Algal biorefinery process utilizes every component of algal biomass to produce multiple useful fuel products. In this technique, acid pretreatment of algal biomass hydrolyzes microalgal carbohydrates into fermentable sugars, makes lipids more extractable and a protein part accessible for additional products. In the present study, Chlorella sorkiniana produced higher quantity of biodiesel than B...
متن کاملMetabolic Engineering of Arabidopsis Plant to Produce Triterpenoid Hydrocarbons for Biofuel
The microalga Botryococcus braunii (B. braunii) can produce extracellular oil in the form of triterpenoid hydrocarbons up to 40 precent of their dry mass. These hydrocarbons with carbon chain lengths ranging from C30 to C40 including botryococcene, squalene and methylated squalenes, are ideal for the production of high quality liquid transport fuels and petrochemical alternatives. However, comm...
