Extreme thermophiles as emerging metabolic engineering platforms

Abstract

Going forward, industrial biotechnology must consider non-model metabolic engineering platforms if it is to have maximal impact. This will include microorganisms that natively possess strategic physiological and metabolic features but lack either molecular genetic tools or such tools are rudimentary, requiring further development. If non-model platforms are successfully deployed, new avenues for production of fuels and chemicals from renewable feedstocks or waste materials will emerge. Here, the challenges and opportunities for extreme thermophiles as metabolic engineering platforms are discussed.
