Countries are investing massively in R & D to find solutions. For instance, Japanese scientists have discovered an enzyme produced by microorganisms in the gut of termites that not only can break down wood cellulose ultra-efficiently, but can do so with no prior chemical processing, easily breaking down carbohydrates into alcohol.
例如日本在白蟻的腸內微生物中發現一種酵素，不僅能以超高效率分解木材纖維素，並可不必事先作化學處理，即可自行將醣分解為酒精。
