Along with the development of agriculture, the yield of straw is large and grows rapidly every year around the world.As a renewable energy source, corn stalk is the fourth largest energy source next to oil, coal and gas.
However, due to the complex structure of straw, the current physical and chemical methods not only consume large amounts of energy but also create the problem of potential air pollution, while biological methods are of low efficiency and need pretreatment via chemical substances. Therefore, how to use straw efficiently has become a problem for us to consider.
Fortunately, we have found a dual-function enzyme, xyn10D-fae1A, which can directly decompose straw and convert it into useful chemical raw materials such as cellulose, lignin, ferulic acid, and xylose. In addition, in order to make more efficient use of cellulose, we have also converted cellulose to butanol and hydrogen while taking into account the shortage of resources.
