Abstract WEST is an MA class superconducting, actively cooled, full tungsten (W) tokamak, designed to operate in long pulses up 1000 s. In support of ITER operation and DEMO conceptual activities, key missions are: (i) qualification high heat flux plasma-facing components integrating both technological physics aspects relevant particle exhaust conditions, particularly for the monoblocks foreseen divertor; (ii) integrated steady-state at confinement, with a focus on power issues. During phase...
Despite various plans to rationalize antibiotic use, resistance in environmental bacteria is increasing due the accumulation of residues environment. This study aimed test ability basidiomycete fungal strains biotransform levofloxacin, a widely-used third-generation broad-spectrum fluoroquinolone, and propose enzyme targets potentially involved this biotransformation. The biotransformation process was performed using strains. Levofloxacin reached 100% after 9 days culture with Porostereum...
An environmental friendly process was developed to produce Arthrospira maxima's biomass from sugarcane vinasse, which generated in a bioethanol production chain, at laboratory and pilot scale. Peptides fractions were than obtained enzymatically hydrolyzed biomass. High microalgae productivities reached (0.150 g L−1 day−1) coupled with significant reduction of BOD COD (89.2 81%, respectively). Three peptide through single or sequential enzymatic hydrolysis. Antioxidant, antimicrobial,...
When ligands and receptors are both attached on surfaces, because of the restriction configurational freedom, their recognition kinetics may be substantially reduced as compared with freely diffusing species. In nature, this reduction influence efficiency capture adhesion circulating cells. Here we show that similar consequences observed for colloids grafted biomolecules used probes diagnostics. We exploit Brownian magnetic self-assemble into linear chains to also resulting one-dimensional...
Mangrove sediments from New Caledonia were screened for xylanase sequences. One enzyme was selected and characterized both biochemically its industrial potential. Using a specific cDNA amplification method coupled with MiSeq sequencing approach, the diversity of expressed genes encoding GH11 xylanases investigated beneath Avicenia marina Rhizophora stylosa trees during wet dry seasons at two different sediment depths. varied more according to tree species season, than respect depth. complete...
Environmental pollution is one of the major problems that world facing today. Several approaches have been taken, from physical and chemical methods to biotechnological strategies (e.g. use oxidoreductases). Oxidative enzymes microorganisms offer eco-friendly, cost-effective processes amenable applications, such as in industrial dye decolorization. The aim this study was screen marine-derived fungal strains isolated three coastal areas Tunisia identify laccase-like activities, produce...
The wastewater from hospitals, pharmaceutical industries and more generally human animal dejections leads to environmental releases of antibiotics that cause severe problems for all living organisms. aim this study was investigate the capacity three fungal strains biotransform fluoroquinolone levofloxacin. degradation processes were analyzed in solid liquid media. Among tested, Coriolopsis gallica strain CLBE55 (BRFM 3473) showed highest removal efficiency, with a 15% decrease antibiogram...
We have studied the effect of shear on stability suspensions made non-Brownian solid particles. demonstrate existence an irreversible transition where particles aggregate at remarkably low volume fractions (phi approximately 0.1). This shear-induced aggregation is dramatic and exhibits a very sudden change in viscosity, which increases sharply after shear-dependent induction time. show that this time related exponentially to rate, reflecting importance hydrodynamic forces reducing repulsive...
Abstract The mission of WEST (tungsten-W Environment in Steady-state Tokamak) is to explore long pulse operation a full tungsten (W) environment for preparing next-step fusion devices (ITER and DEMO) with focus on testing the ITER actively cooled W divertor tokamak conditions. Following successful completion phase 1 (2016-2021), 2 started December 2022 lower made entirely ITER-grade mono-blocks. A boronization prior first plasma attempt allowed smooth startup new divertor. Despite reduced...
We introduce a general methodology based on magnetic colloids to study the recognition kinetics of tethered biomolecules. Access full reaction is provided by an explicit measure time evolution reactant densities. Binding between single ligand and its complementary receptor here limited colloidal rotational diffusion. It occurs within binding distance that can be extracted reaction-diffusion theory properly accounts for Brownian dynamics. Our geometry allows us probe large diversity...
5-Hydroxymethylfurfural (HMF), a major residual component of lignocellulosic bio-refinery process, can be transformed into fundamental building blocks for green chemistry via oxidation. While chemical methods are well established, interest is also being directed the enzymatic oxidation HMF bio-plastic precursor 2,5-furandicarboxylic acid (FDCA). We demonstrate that three glyoxal oxidases (PciGLOX) isoenzymes from Basidiomycete fungus Pycnoporus cinnabarinus were able to oxidize HMF, with...
The textile industry generates huge volumes of colored wastewater that require multiple treatments to remove persistent toxic and carcinogenic dyes. Here we studied the decolorization a recalcitrant azo dye, Reactive Black 5, using laccase-like active cell-free supernatant from Coriolopsis gallica. Decolorization was optimized in 1 mL reaction mixture response surface methodology (RSM) test influence five variables, i.e., activity, dye concentration, redox mediator (HBT) pH, temperature, on...
Tissue engineering (TE) is the use of a combination biological cells, and materials methods, suitable biochemical physicochemical factors, in order to improve or replace functions. It has brought advent entirely new classes hierarchically organized, multiporous materials, consisting both chemically biologically produced parts. Here, we aim at contributing unsettled question mechanical functioning bone tissue-engineering scaffolds with tissue-engineered bone—from theoretical applied mechanics...
Even if the ocean represents a large part of Earth’s surface, only few studies describe marine-derived fungi compared to their terrestrial homologues. In this ecosystem, have had adapt salinity and plant biomass composition. This articles growth five marine isolates tuning lignocellulolytic activities under different conditions, including salinity. A de novo transcriptome sequencing assembly were used in combination with proteomic approach characterize Carbohydrate Active Enzymes (CAZy)...
