Enzymatic degradation of polylactic acid (PLA)

Applied Microbiology and Biotechnology, Год журнала: 2024, Номер 108(1)

Опубликована: Июль 10, 2024

Environmental concerns arising from the increasing use of polluting plastics highlight polylactic acid (PLA) as a promising eco-friendly alternative. PLA is biodegradable polyester that can be produced through fermentation renewable resources. Together with its excellent properties, suitable for wide range applications, has increased significantly over years and expected to further grow. However, insufficient degradability under natural conditions emphasizes need exploration biodegradation mechanisms, intending develop more efficient techniques waste disposal recycling or upcycling. Biodegradation occurs secretion depolymerizing enzymes, mainly proteases, lipases, cutinases, esterases, by various microorganisms. This review focuses on enzymatic degradation presents different enzymes were isolated purified PLA-degrading microorganisms, recombinantly expressed. The depicts main characteristics including recent advances analytical methods used evaluate enantiopurity activity. While complete solid particles still difficult achieve, future research improvement enzyme properties may provide an avenue development advanced procedures upcycling, utilizing building blocks applications envisaged circular economy principles. KEY POINTS: • Enzymes promisingly utilized Natural recombinant depolymerases activity evaluation are summarized. Approaches improve discussed.

Effect of Hyaluronan Molecular Weight on the Stability and Biofunctionality of Microfibers Assembled by Interfacial Polyelectrolyte Complexation

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер 17(2), С. 4199 - 4209

Nervous system disorders are characterized by a progressive loss of function and structure neurons that ultimately leads to decline in cognitive motor functions. In this study, we used interfacial polyelectrolyte complexation (IPC) produce fibers for neural tissue regeneration. IPC is processing method allows spinning sensitive biopolymers. The rate the properties biopolymers (charge molecular weight) influence different characteristics such as size stability, among others. We two major components neuronal stem cell niche, polycationic collagen (Col) polyanionic hyaluronic acid (HA), obtain bioactive fibers. tested HA with weights found medium high (350 1200 kDa, respectively) enabled drawing microfibers homogeneous distribution Col HA, whereas low-molecular-weight (40 kDa) did not allow spinning. obtained showed swelling ability physiological buffer: their diameters increased more than 5-fold from dry state. At these conditions, tensile storage moduli were similar nervous tissues. Collagenase hyaluronidase change morphology up 3 days but reduced 2- 3-fold. Assays PC12 neuronal-like cells support adhesion viability regardless weight HA.

Bimetallic nanozymes synergize to regulate the behavior of oxygen intermediates and substrate HMF adsorption

Chemical Communications, Год журнала: 2024, Номер 60(67), С. 8860 - 8863

Опубликована: Янв. 1, 2024

We have constructed a bimetallic (CoNiP) nanozyme, leveraging the synergistic effect of cobalt and nickel, which efficiently catalyzes oxidation TMB from colorless to ox-TMB (blue). Density functional theory (DFT) calculations further highlight pivotal role this in improving adsorption energy oxygen intermediates, accelerating catalytic process.
