botryococcus braunii 10

Can anybody update me on this microalga and its potential for being used as biofuel?

    Though B. braunii can be potentially used as a biodiesel feedstock, the processes required are relatively complex.Botryococcus braunii (B. braunii, Bb) is one of the most exciting and prized algae species with regards to the potential for production of biofuels. Unlike many other species of algae which require, in some form, the extraction of oil found with the cells, Botryococcus braunii secretes its hydrocarbon oils outside of the cell wall for easy collection. Additionally, up to 86% of its dry weight can be composed of long chain hydrocarbons.

    are you talking about the process need for its mass production? Are those processes complex. Is it true that it does not produce that much biomass

    Botryococcus braunii has great potential for algaculture because of the hydrocarbons it produces, which can be chemically converted into fuels. Up to 86% of the dry weight of Botryococcus braunii can be long chain hydrocarbons . The vast majority of these hydrocarbons are botryocuccus oils: botryococcenes, alkadienes and alkatrienes. Transesterification can NOT be used to make biodiesel from botryococcus oils. This is because these oils are not 'vegetable oils' in the common meaning, in which they are fatty acid triglycerides. While botryococcus oils are oils of vegetable origin, they are inedible and chemically very different, being triterpenes, and lack the free oxygen atom needed for transesterification. Botryococcus oils can be used as feedstock for hydrocracking in an oil refinery to produce octane (gasoline, a.k.a. petrol), kerosene, and diesel. Botryococcenes are preferred over alkadienes and alkatrienes for hydrocracking as botryococcenes will likely be transformed into a fuel with a higher octane rating.

    Compared to other green algae species it has a relatively thick cell wall that is accumulated from previous cellular divisions; making extraction of cytoplasmic components rather difficult. Fortunately, much of the useful hydrocarbon oil is outside of the cell. This gives rise to the hope that the algae will not have to be killed in order to extract its useful oil. Several methods are available to extract the botryococcene. One that shows the most promise is the use of hexane as a solvent. If used at the proper molarity, it does not kill the majority of the Bb, while extracting the botryococcene.

    thanks for the responses. I was just curious to know if anybody tried genetic engineering on this alga to make it fast growing??
