To lower the cost of biomass conversion, approaches to decrease lignin content or alter its structure to allow ease of removal may be employed. This work aims to study genes involved in lignin biosynthesis and modification, in order to identify points in the pathway that can be targeted to ...
Therefore, tough it looks rather complex, its molecular structure consists of atoms only of carbon, hydrogen and oxygen. What is lignin and its function? Lignin is a durable, waterproof polymer that serves as a "backbone" for plants, providing structure and support. It serves as a barrier to...
The industrial applications of lignin are limited critically due to its complex nature and undefined chemical structure. For example, commercially purchased kraft lignins from softwoods may have different compositions as well as their structures [14]. Furthermore, the lignin-carbohydrate complex (LCC) ...

These sites of glycosylation, Ca2+ binding regions, and four disulfide linkages shown to stabilize the structure of LiP enzyme. LiPs are reported to oxidize substrates not oxidized by other peroxidases because of its high redox potential (Morales et al., 2012). During this LiP-mediated oxidation...

, the most commonly found ranges are cellulose: 38%–50%;hemicellulose: 23%–32%, and lignin: 15%–25%[38]. Lignin is an amorphous substance and has an aromatic nature and a complex structure. Lignin can be an alternative source for benzene, currently obtained from petroleum, and can...
lignin in softwoods is composed of mostly guaiacyl units (more than 95%) and small amounts of p-hydroxyphenyl units, whereas the lignin from agroplants contain all three units (H, G, S) in significant amounts with different ratios, making its structure more complex (del Río et al., 201...
Synthesis mechanism from lignin to CNT fibers and its respective processing schematic. Full size image In order to realize continuous preparation of CNT fibers using lignin, it is necessary to select appropriate solvents. In addition to good solubility, the simple structure and low cost of the solv...
