Suppression of Lignin Repolymerisation to Enhance Cellulose Bioconversion and Lignin Valorisation – A Review

The recent discovery that the prevention of lignin repolymerisation/condensation in lignocellulosic biomass pretreatment can both enhance bioconversion cellulose and quality obtained lignin, has brought a lignocellulose biorefinery closer to reality. In this work, development approach last advancements are reviewed. review reveals successful implementation for wide range substrates including softwood, hardwood, agricultural residues. As well, it is shown various technologies, steam, acid organosolv processes. Recent developments involve new greener additives which prevent repolymerisation, saccharification at industrially realistic conditions high-yield fermentation. addition, first applications these processes reviewed, showcasing its enhanced functionalisation use polymers, as well depolymerisation aromatic monomers. progresses bring prospect valorise all fractions biomass.
