“…On the other hand, PAL/TAL, C4H, C3H and 4CL are not suitable targets for genetic manipulation to alter lignin composition of plants (enzymes that are downstream from CCR) (Figure 3) [30]. Changes to enzyme activities may be achieved by suppressing the appropriate gene(s) expression [12,23,30,35,36,176,177]. Generally, an increase in G/S ratio leads to improved biomass conversion.…”

Supramolecular Self-Assembled Chaos: Polyphenolic Lignin’s Barrier to Cost-Effective Lignocellulosic Biofuels

et al. 2010

Phenylpropanoid metabolism yields a mixture of monolignols that undergo chaotic, non-enzymatic reactions such as free radical polymerization and spontaneous selfassembly in order to form the polyphenolic lignin which is a barrier to cost-effective lignocellulosic biofuels. Post-synthesis lignin integration into the plant cell wall is unclear, including how the hydrophobic lignin incorporates into the wall in an initially hydrophilic milieu. Self-assembly, self-organization and aggregation give rise to a complex, 3D network of lignin that displays randomly branched topology and fractal properties. Attempts at isolating lignin, analogous to archaeology, are instantly destructive and nonrepresentative of in planta. Lack of plant ligninases or enzymes that hydrolyze specific bonds in lignin-carbohydrate complexes (LCCs) also frustrate a better grasp of lignin. Supramolecular self-assembly, nano-mechanical properties of lignin-lignin, ligninpolysaccharide interactions and association-dissociation kinetics affect biomass deconstruction and thereby cost-effective biofuels production.

“…4c) was approximately 100-fold less in WT plants as compared to the signals observed for G-and S-lignin marker ions in these plants. Ions associated with 5-OHG-lignin (arising from 5-hydroxyconiferyl alcohol; Lam et al 1996;Rastogi and Dwivedi 2008) were characterized using the major ion at m/z 357 (Fig. 4d).…”

“…H-lignin (or H-unit) arises from p-coumaryl alcohol, G-lignin from coniferyl alcohol, and S-lignin from sinapyl alcohol (Boerjan et al 2003). However, plants have the capacity to incorporate a range of molecules such as 5-hydroxyconiferyl alcohol and diVerent cinnamylaldehydes into the lignocellulosic matrix (Humphreys et al 1999;Anterola and Lewis 2002;Boerjan et al 2003;Barrière et al 2004;Shadle et al 2007;Rastogi and Dwivedi 2008). Grasses also contain signiWcant amounts of p-coumaric acid (pCA) and ferulic acid (FA), predominantly crosslinked to cell wall lignin and polysaccharide through ester and ether linkages (Grabber et al 1991;Dixon et al 2001;Chen et al 2002;Boerjan et al 2003;Grabber and Lu 2007).…”

A degradable starch/lignin blend film was prepared using corn starch and sodium lignosulfonate via a casting and solvent evaporation method. The effect of sorbitol content on the swelling properties of starch/lignosulfonate blend films was investigated. The effect of lignosulfonate content on the swelling and mechanical properties was also studied. The results showed that when the mass ratio of sorbitol to starch changed over a wide range, from 0:9 to 9:9, the water absorption of the blend films increased at first and then decreased. When the mass ratio of lignosulfonate to starch changed in the same range, the ultimate stress of the blend films decreased markedly, while the water absorption and elongation at break did not show any regular pattern. When the mass ratios of sorbitol to starch and lignosulfonate to starch were both 6:9, the resultant film presented good elasticity and improved hydrophobicity compared to those without lignosulfonate.
