En Route Toward Sustainable Polycarbonates Via Large Cyclic Carbonates

open access: yesChemSusChem, Accepted Article.
This review reports an up‐to‐date overview of the synthetic methodologies developed for the preparation of large cyclic organic carbonates with ≥ 6‐membered rings (6M‐CCs and above), highlighting the most sustainable synthetic pathways employing diols (including renewable‐based ones) and non‐hazardous carbonyl sources, e.g., linear organic carbonates ...

Continuous Flow Depolymerization of Polycarbonates and Poly(lactic acid) Promoted by Supported Organocatalysts

open access: yesChemSusChem, EarlyView.
The chemical recycling of plastic waste plays a crucial role in promoting a circular economy. This work reports on the use of recyclable heterogeneous organocatalysts to promote common polycarbonate and polyester glycolysis. Poly(lactic acid) and bisphenol A polycarbonate are here depolymerized at low temperatures in a continuous approach, proving ...

Properties of snail shell-immobilized lipase of Aspergillus pseudotamarii and its application in butyl butyrate synthesis

open access: yesJournal of BioScience and Biotechnology
In this study, attempts were made to evaluate shells of egg and snail, crystal beads, and kaolin clay as suitable carriers for the immobilization of purified lipase produced by Aspergillus pseudotamarii.

Valorization of Apple Pomace: Production of Phloretin Using a Bacterial Cellulose‐Immobilized β‐Glycosidase

open access: yesChemSusChem, EarlyView.
This study presents a whole valorization of apple processing waste: phloretin is efficiently produced from phloridzin (abundantly found in apple residues), using a β‐glycosidase immobilized on bacterial cellulose in a biphasic system. Notably, bacterial cellulose is derived from fermentation of apple pomace sugars, making both the enzyme carrier and ...

Inhibition of lipases by ∊-polylysine

open access: yesJournal of Lipid Research, 2003
Oral administration of ∊-polylysine to rats reduced the peak plasma triacylglycerol concentration. In vitro, ∊-polylysine and polylysine strongly inhibited the hydrolysis, by either pancreatic lipase or carboxylester lipase, of trioleoylglycerol (TO ...

Combining photocatalytic oxidation of β‐chlorohydrins with carbonyl bioreduction in a deracemization approach

open access: yesChemSusChem, Accepted Article.
Enantiopure β‐chlorohydrins are valuable intermediates in organic synthesis, acting as chiral building blocks for obtaining biologically active compounds. This work presents a one‐pot two‐step linear sequence for the efficient deracemization of β‐chlorohydrins by combining a photocatalytic alcohol oxidation with a stereoselective carbonyl bioreduction ...

The endocannabinoid system regulates both ependymoglial and neuronal cell responses to a tail amputation in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The endocannabinoid system is a neuromodulatory system implicated in cellular processes during both development and regeneration. The Mexican axolotl, one of only a few vertebrates capable of central nervous system regeneration, was used to examine the role of the endocannabinoid system in the regeneration of the tail and spinal ...
