Lignin compound wastes are generated as a result of agricultural and industrial practices. Microorganism-mediated bio-catalytic processes can depolymerize and utilize lignin eco-friendly. Although fungi have been studied since several decades for their ability to depolymerize lignin, strict growth conditions of fungus limit it's industrial application. Compared with fungi, bacteria can tolerate wider pH, temperature, oxygen ranges and are easy to manipulate. Several studies have focused on bacteria involved in the process of lignin depolymerization and utilization. Pseudomonas have been used for paper mill wastewater treatment while Rhodococcus are widely reported to accumulate lipid. In this review, the recent studies on bacterial utilization in paper wastewater treatment, lignin conversion to biofuels, bioplastic, biofertilizers and other value-added chemicals are summarized. As bacteria possess remarkable advantages in industrial production, they may play a promising role in the future commercial lignin utilization.

Effective fractionation of lignocellulose into hemicellulose, cellulose, and lignin is the precondition for full-component valorization. Generally, harsh reaction conditions are used to improve fractionation efficiency, which leads to severe lignin condensation and inhibits its value-added applications. To address this issue, a novel biphasic system consisting of molten salt hydrates (MSHs) and n-butanol was developed for birch fractionation.

Herein, we report a novel electrochemical hydrogenolysis method for β-O-4 bond cleavage by using carbon foam as the cathode and waste aluminum as the anode. The reaction takes place at the cathode, producing ketones and phenolic compounds. Employing waste aluminum as the anode could avoid anodic excessive oxidation of phenols.

Lignin, as the largest renewable aromatic resource, has significant opportunities for producing high-value products via catalytic depolymerization. However, its complex structure and stable chemical bonds present challenges to its transformation. This study explores the catalytic depolymerization of lignin to aromatic monomers by means of Dawson-type phosphomolybdovanadate polyoxometalates (POMs), understanding the underlying mechanisms.

The microbiota within the guts of insects plays beneficial roles for their hosts, such as facilitating digestion and extracting energy from their diet. The African palm weevil (APW) lives within and feeds on the high lignin-containing trunk of palm trees; therefore, their guts could harbour a large community of lignin-degrading microbes. In this study, we aimed to explore the bacterial community within the gut of the APW larvae, specifically with respect to the potential for lignin degradation in various gut segments as a first step to determining the viability of mining bacterial lignin-degrading enzymes for the bioconversion of lignocellulosic biomass to biofuels and biomaterials.
