Open in a separate window Production of value-added compounds from a renewable aromatic polymer, lignin, has proven to be challenging. Chemical procedures, involving harsh reaction conditions, are costly and often result in nonselective degradation of lignin linkages. Therefore, enzymatic catalysis with selective cleavage of lignin bonds provides a sustainable option for lignin valorization. Ds-GST1 also demonstrated activity on polymeric synthetic lignin fractions, shown by a decrease in molecular weight distribution of the laccase-oxidized guaiacyl dehydrogenation polymer. In addition to a possible role of Ds-GST1 in intracellular catabolism of lignin-derived aromatic compounds, the cleavage of the most abundant linkages in lignin under mild reaction conditions makes this biocatalyst an attractive green alternative in biotechnological applications.

These are what have made possible civilization, as well as culture, its constant and necessary companion. A thorough understanding of what civilization and culture are requires a knowledge of all the qualities that make up human nature and a full understanding of world history and all historical developments. To be truly world history, an account of the past must not only retell what happened but must also relate events and people to each other. It must inquire into causes and effects. It must try to discern falsehood in the old records, such as attempts of kings to make themselves look better than they really were.
