Lignin is an organic substance binding the cells, fibres and vessels which constitute wood and the lignified elements of plants, as in straw. After cellulose, it is the most abundant renewable carbon source on Earth.
Research is exploring how to add value to lignin by breaking it down into small molecules that are structurally similar to oxygenated hydrocarbons. These renewable chemicals are key components in many ...
The polysaccharide components of plant cell walls are highly hydrophilic and thus permeable to water, whereas lignin is more hydrophobic. The crosslinking of polysaccharides by lignin is an obstacle for water absorption to the cell wall. Thus, lignin makes it possible for the plant's vascular tissue to conduct water efficiently. [15]
lignin, complex oxygen-containing organic polymer that, with cellulose, forms the chief constituent of wood. It is second to cellulose as the most abundant organic material on Earth, though relatively few industrial uses other than as a fuel have been found.
Lignin is a complex organic polymer found embedded within the cell walls of most plants, where it acts as a binder holding the plant fibers together. It is one of the most abundant organic polymers on Earth, second only to cellulose, and constitutes between 20 to 35% of the dry mass of wood.
This book brings together world-leading experts in lignin utilization to present and review the most recent discoveries in lignin valorization to highlight opportunities going forward to utilize lignin more efficiently and sustainably. Emphasis is placed on very recent, emerging topics in chemical and biological catalysis for lignin valorization.
Lignin is one of the main components of plant cell wall and it is a natural phenolic polymer with high molecular weight, complex composition and structure. Lignin biosynthesis extensively contributes to plant growth, tissue/organ development, ...
