Chemical Triggers High Yield of Algal Biofuel Posted by Jacintha on Thu October 07 2010 11:04:02 AM


A  chemical trigger discovered at Montana State
University helps  algal biofuel
production  double in yield and in far
less time.



The chemical
trigger is a well-timed dose of bicarbonate, a low-cost, easy-to-use
chemical.  When given to algae during a
specific point in its growth cycle, the bicarbonate doubles the rate of
production of triacylglycerol, the key precursor to biodiesel. Some cultures
have shown nearly three times faster rates of triacylglycerol accumulation,
which would result in significant cost savings for biofuel manufacturers. This
effect has been shown in both diatoms and in green alga.


The bicarbonate also shortens the time it takes to
reach high lipid yields.



The technology is available
for licensing to interested companies and entrepreneurs.

Thailand serious about Algae Biofuel Posted by Jacintha on Sun September 12 2010 02:58:04 AM 52

Sucess of palm oil has placed Algae Biofuel as an attractive option to the dept of Alternate Energy, Thailand.  They realize the crux is identifying the right algae.Two Universities, the Chanthaburi campus ofBurapha University, focusing on marine algae, and Kasetsart University, which is looking into freshwater algae,  are being sponsored by the Dept of Alternate Energy. 

Direct Wet Algae to Biodiesel Posted by Jacintha on Thu September 02 2010 04:40:19 AM 1


Researchers at the University of Michigan have published the feasibility of a two-step hydrolysis-solvolysis process to produce biodiesel directly from wet algal biomass, eliminating the need for costly biomass drying, organic solvent extraction and catalysts. The paper on the process was published in the ACS journal Energy & Fuels. 

In the first step, wet algal biomass contained 80 percent moisture and was reacted with subcritical water to hydrolyze intracellular lipids, conglomerate cells into an easily filterable solid that retained the lipids and produced a sterile, nutrient-rich aqueous phase. In the second step, the wet, fatty acid-rich solids underwent supercritical transesterification with ethanol to produce fatty acid ethyl esters (FAEEs). The team used Chlorella vulgaris algae, which contained 53.3 percent lipid content.
