straw, in a sustainable way. This could then be used to produce alternative fuels. "Enzymes produced by the tiny creatures are able to break down woody cellulose and turn it into energy-rich sugars meaning that gribble could convert wood and straw into liquid biofuel." One particular enzyme produced in a special organ in the body of the gribble called the hepatopancreas and secreted into its gut has recently been identified and characterized: the GH7 cellobiohydrolase, LqCel7B. This enzyme has been shown to be highly effective in a salty environment such as that in which the gribble lives.
