Secreting bacteria eliminate cost barriers for renewable biofuel production
Source : physorg.com
To get cyanobacteria to more readily release their precious, high fat cargo, ASU researcher Roy Curtiss (standing) and postdoctoral researcher Xinyao Liu, placed a suite of genes into photosynthetic bacteria that produced enzymes to degrade membrane lipids, poking holes in the membranes to release free fatty acids into the water. In a clever feat of genetic reprogramming of the cells, the enzymes are only produced when carbon dioxide - a vital ingredient of bacterial growth - is removed from their environment. Credit: Biodesign Institute at Arizona State University A Biodesign Institute at Arizona State University research team has developed a process that removes a key obstacle to producing low-cost, renewable biofuels from bacteria. The team has reprogrammed photosynthetic microbes to secrete high-energy fats, making byproduct recovery and conversion to biofuels easier and potentially more commercially viable.
