Bacterial transformation of lignin: key enzymes and high-value products

Biotechnology for Biofuels and Bioproducts, Год журнала: 2024, Номер 17(1)

Опубликована: Янв. 3, 2024

Lignin, a natural organic polymer that is recyclable and inexpensive, serves as one of the most abundant green resources in nature. With increasing consumption fossil fuels deterioration environment, development utilization renewable have attracted considerable attention. Therefore, effective comprehensive lignin has become an important global research topic, with goal environmental protection economic development. This review focused on bacteria enzymes can bio-transform lignin, focusing main ways be utilized to produce high-value chemical products. Bacillus demonstrated prominent effect degradation, 89% degradation by cereus. Furthermore, several bacterial were discussed act consisting dye-decolorizing peroxidases laccase. Finally, low-molecular-weight compounds converted into value-added products through specific reaction pathways. These may potential candidates for efficient future, providing method conversion. In addition, metabolic pathways convert lignin-derived aromatics intermediates "biological funnel", achieving biosynthesis The this funnel" aromatic address heterogeneous issue obtained via depolymerization. also simplify separation downstream target provide avenues commercial application conversion

Bio-Based Valorization of Lignin-Derived Phenolic Compounds: A Review

Biomolecules, Год журнала: 2023, Номер 13(5), С. 717 - 717

Опубликована: Апрель 22, 2023

Lignins are the most abundant biopolymers that consist of aromatic units. obtained by fractionation lignocellulose in form "technical lignins". The depolymerization (conversion) lignin and treatment depolymerized challenging processes due to complexity resistance lignins. Progress toward mild work-up lignins has been discussed numerous reviews. next step valorization is conversion lignin-based monomers, which limited number, into a wider range bulk fine chemicals. These reactions may need chemicals, catalysts, solvents, or energy from fossil resources. This counterintuitive green, sustainable chemistry. Therefore, this review, we focus on biocatalyzed e.g., vanillin, vanillic acid, syringaldehyde, guaiacols, (iso)eugenol, ferulic p-coumaric alkylphenols. For each monomer, its production summarized, and, mainly, biotransformations provide useful chemicals discussed. technological maturity these characterized based on, scale, volumetric productivities, isolated yields. compared with their chemically catalyzed counterparts if latter available.
