Abstract

Of all the renewable resources, wood or lignocellulosic biomass is the most abundant. In addition, it is carbon-neutral and its use does not compete with that of food. For these reasons, increasing attention is being paid to the sustainable production and use of lignocellulosics. However, lignocellulosics are structural materials that confer mechanical strength to plant bodies, and therefore, they are inherently recalcitrant to biochemical conversion. To overcome this recalcitrance, there has been substantial research and development of metabolic engineering to reduce lignin content to levels that are effective for enzymatic saccharification. As well as enzymatic saccharification coupled with fermentation, there are a number of other biomass conversion methods. Hence, it is now important to metabolically engineer lignocellulosics for optimal conversion using these other methods. During the last 20 years, significant advances have been made in understanding lignin biosynthesis, and it is now possible to control the structures and contents of lignins in various plant species. In this seminar, the current status and future prospects of lignin metabolic engineering will be discussed.
