Lignin forms a large part of plant biomass. It is a highly heterogeneous polymer of 4-
hydroxyphenylpropanoid units and is embedded within polysaccharide polymers forming …

Lignin is an abundant plant‐based biopolymer that has found applications in a variety of
industries from construction to bioethanol production. This recalcitrant branched polymer is …

As the second most abundant biopolymer on earth after cellulose, lignin is considered to be
an alternative source of various polymers and biomaterials since it can be cleaved into a …

Lignin, an aromatic polymer found in plants, has been studied for years in many biological
fields. Initially, when biofuel was produced from lignocellulosic biomass, lignin was regarded …

Covering: up to 2011 Lignin is a heterogeneous aromatic polymer found as 10–35% of
lignocellulose, found in plant cell walls. The bio-conversion of plant lignocellulose to …

Abundant lignocellulosic biomass from various industries provides a great potential
feedstock for the production of value-added products such as biofuel, animal feed, and …

Lignin is a robust material that is considered useless because it has an inhibitory effect on
microbes and acts as a physical barrier for cellulose degradation. Therefore, it has been …

Lignin is a complex phenylpropanoid biopolymer conferring mechanical strength to plant
cell walls. Biorefineries, along with pulp and paper industry, generate large quantities of …

The conversion of polymeric lignin from plant biomass into renewable chemicals is an
important unsolved problem in the biorefinery concept. This article summarises recent …
