genetically-engineered cyanobacterium produces and secretes

Genetically-engineered cyanobacterium eliminates biomass step to
produce ready-to-use diesel fuel or ethanol   Joule Unlimited, a
Cambridge-based producer of alternative energy technologies that
was founded in 2007, developed a genetically engineered
organism called a cyanobacterium, which uses water, sunlight and
carbon dioxide to produce and secrete renewable fuels.    Until
now, researchers have created fuel from solar energy through the
use of corn and algae. But creating ethanol from corn or
extracting fuel from algae on a large scale can be costly due to
biomass. The process consists of having to grow tons of algae or
corn, harvest it and destroy it in order to extract the fuel,
which must then be treated before it can be used.   But
according to biologist Dan Robertson, Joule Unlimited's top
scientist, the cyanobacterium el
