Genomatica Makes Methyl Ethyl Ketone from Microbes Ingesting Sugar

California licensor of technology thinks solvent MEK could get to market in 2010, reviving now-closed ethanol plants and serving global markets.

San Diego-based Genomatica said today it has developed a second chemical using a microbes instead of petroleum.

CEO Christopher Gann told the Cleantech Group that the company engineered a way to produce methyl ethyl ketone (MEK) from microbes ingesting sugar. The MEK can be made in the same fermentation facilities as ethanol plants, providing a use for shuttered or underused plants and removing the capital cost to build dedicated facilities

MEK is an industrial solvent used in paints, coatings or varnishes, especially for the furniture-making industry, that is typically made with petroleum. About half the market goes to about a dozen large buyers and is distributed by railcar, while the rest is typically produced in plants and put into drums.

The worldwide market for MEK is 3 billion dry pounds, or about $2 billion. In the U.S., the market is just 400 million pounds—making the global markets a focus for Genomatica.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
