Lignin Depolymerization for Its Valorization

Beyond Yield Optimization: The Impact of Organosolv Process Parameters on Lignin Structure

“…The principles of the processes and their advantages and disadvantages are described in detail in the literature. [31,32] In recent decades, the focus has been on environmentally friendly biorefinery processes for the full utilization of renewable raw materials and the extraction of lignin with high added value, which is precisely the approach of the organosolv process. [5] Most organic solvents used in the organosolv process are either polar protic or polar aprotic solvents.…”

Continuous Separation and Purification of Chemical Species by Continuous Liquid–Liquid Partition Chromatography Implemented with Membrane-Based Phase Separators

“…Following the validation of our model, we then present an example of natural product separation centered around some of the major components from the depolymerization of softwood lignin. Softwood lignin has recently been the center of many reviews for its economic optimization and valorization 34,35 through its use in biorefining 36−39 and applicability as a renewable biomass to use as a starting material in the polymer industry. 40−43 Finally, we present an enantioseparation of racemic propranolol, a β-adrenergic receptor blocker drug, using a chiral selector.…”

Recently, there has been increasing interest in using chiral additives which preferentially bond with one enantiomer to skew partitioning through a three-point interaction model, as seen in Figure , and many reviews have been performed of existing studies. ,− …”

Microplastic emerging pollutants – impact on microbiological diversity, diarrhea, antibiotic resistance, and bioremediation

“…Depending on the organisms, molecular mass and size of MPs and other environmental attributes greatly influence the microbes-assisted transformation. 20,21 Microplastic recently got tremendous attention from researchers of biological and ecological domains. Although the term microplastic is debatable, 22 the environmental impact of microplastics has been extensively studied.…”
