DELIGNIFICATION Meaning and
Definition
-
Delignification is a process that involves the removal or dissolution of lignin from plant materials, such as wood or other types of cellulosic biomass. Lignin is a complex polymer found in the cell walls of plants and is primarily responsible for providing structural support. However, it also hinders the access to cellulose fibers, which are an important source of renewable materials and biofuels.
During delignification, one of the main objectives is to separate lignin from cellulose and hemicellulose components in order to improve the overall accessibility of cellulose fibers. This can be achieved through various methods, including chemical, biological, or physical treatments.
Chemical delignification methods typically involve the use of strong alkaline solutions, such as sodium hydroxide or sodium sulfite, to break down and remove lignin. These processes often require high temperatures and pressure to enhance the efficiency of lignin removal.
Biological delignification, on the other hand, involves the use of enzymes or microorganisms that possess lignin-degrading capabilities. These biological agents can selectively target and degrade lignin, allowing for the separation of cellulose fibers.
Physical delignification methods generally rely on mechanical forces, such as grinding or milling, to physically disrupt and remove lignin from the biomass.
Overall, delignification plays a crucial role in making plant-based resources more accessible for various applications, such as pulp and paper production, biofuels, and biorefinery processes.

Etymology of DELIGNIFICATION
The word "delignification" comes from the combination of the prefix "de-" and the word "lignin".
The prefix "de-" is of Latin origin meaning "reversing" or "removing". It is commonly used in English to indicate negation or removal.
The word "lignin" is derived from the Latin word "lignum", which refers to wood. Lignin is a complex polymer that is a key component of the cell walls in plants, particularly in wood. It provides strength and rigidity to plant tissues.
Therefore, "delignification" refers to the process of removing or breaking down lignin from plant materials, most commonly from wood, for various purposes such as pulp and paper production, biofuel production, or biorefining.
