Lignocellulosic biomasses have been used for biofuels, mainly bio-ethanol. The abundant avaiability of the raw material make the use of biomasses ideal. With the rise of carbon emission, biomasses can be used to substitue the need for carbon based fuel, as long as, the biomass is carbon neutral.<ref>Carroll, Andrew; Somerville, Chris (June 2009).

    Energy Transformation

    When Phe 59 is substituted with His and Tyr 101 is substituted with Phe, the k (app/cat) decreases in activity by 15-10 folds. The Lys 134 substitution of Met inhibits the enzyme activity. Phenylazophenol inhibits the LsdA-catalyzed cleavage of lignostilbene with a competitive and uncompetitive inhibition.
