Hello BEST,

A Yale research team has been working to simplify the process of 
extracting the lipids from algae in order to convert them into 
biodiesel. Lindsey Soh, a graduate student working under Julie 
Zimmerman, Ph.D., has been using supercritical carbon dioxide in an 
efficient and environmentally friendly single-step process. 
Supercritical carbon dioxide is already used industrially for such 
processes as decaffeinating coffee, possibly allowing for an easy 
transition from a laboratory procedure to an industrialized process.


Cheers,
