LS9 is putting the bio into biogasoline by using modified bacteria to directly produce hydrocarbons instead of ethanol or other intermediates, according to the BioConversion Blog, quoting Technology Review. LS9 has a number of big backers and is part funded by Vindod Khosla , the firm plans to build a trial plant in California to test the process.
I like the comment by Jim McMillan, principal biochemical engineer in the National Renewable Energy Laboratory's Bioenergy Center, based in Golden, CO he spoke to Technology Review and said: .
"I don't doubt that [making hydrocarbon fuel from microbes] can be done; the question is how quickly and at what cost."
I suggest that the difficulty will not be in the production process, but rather in the yield, and whether biological routes to biogasoline can be more efficient than using Fischer-Tropsch technology on gasses produced thermally degraded wood chips
