Erdem, Elif. „NADPH dependent oxyfunctionalization by Baeyer-Villiger monooxygenases in cyanobacteria“. Electronic Thesis or Diss., Aix-Marseille, 2022. http://www.theses.fr/2022AIXM0119.
Der volle Inhalt der QuellePoly-ɛ-caprolactone (PCL) is a biodegradable polymer of interest, synthesised by the action of peracetic acid, a large-scale explosive reagent, on cyclohexanone. Baeyer-Villiger monooxygenases (BVMOs) catalyse this oxidation under mild conditions but require the stoichiometric addition of organic auxiliary compounds for NADPH cofactor recycling. Furthermore, in whole-cell processes, the oxygen supply, often limited by the transfer rate and cell respiration, caps the usable cell density and thus the volumetric productivity. Recently, recombinant cyanobacteria producing BVMO made possible to use H2O as an electron donor and exploit photosynthetic O2 production, albeit with low productivity (by-product formation). Here, we described an alternative process based on the cloning of a new BVMO, from the bacterium Burkholderia xenovorans, in Synechocystis PPC6803 and in an engineered strain, Synechocystis ∆flv1, for which the photosynthetic electron transport chain (PETC) was partially redesigned via the deletion of flavodiiron proteins. Thus, high specific activities (25 U.gDCW-1) were achieved at high cell densities. We thus demonstrated the potential of oxygenic cyanobacteria as a chassis for the enzymatic oxidation of ketones, improving the atom economy of redox biocatalysis and providing oxygen for oxyfunctionalisation reactions. The process described is a sustainable process, using light as an energy source, water and carbon dioxide as sources of hydrogen, oxygen and carbon, and meets the requirements of green chemistry
Bilodeau, Philippe. „Mesure par microscopie holographique numérique des propriétés viscoélastiques des cellules entières“. Master's thesis, Université Laval, 2019. http://hdl.handle.net/20.500.11794/37528.
Der volle Inhalt der QuelleThe study of viscoelastic properties of whole-cell by optical microscopy allows one to obtain unique information on cell features. It is all the more important to assess those properties all along cultured cell maturation to extract information on its development and health. However, a vast majority of imaging techniques require a marking agent, whilst methods to measure viscoelastic properties are equally invasive. The use of digital holographic microscopy is proposed, since this method allows to image cell culture in real-time without a marking technique and provides quantitative images. Moreover, digital holographic microscopy provides screening deformation at nanoscopic scale induced on cells, without physical contact between the cells and an external instrument. The goal of this project is to develop shear flow assays allowing precise and non-invasive measurements of whole-cell viscoelastic properties. Cell deformation responses caused by the fluid shear stress are interpreted by viscoelastic models where rigidity and viscosity constants are extracted for the whole cell culture simultaneously. Results have shown that shear flow assays allow non-invasive whole-cell measurements of viscoelastic properties. A significant difference between cell properties of NIH 3T3, HEK 293T/17 and neurons have been found. The rigidity constant E1 and the viscosity constant h2 from Standard and Burgers models are viscoelastic properties to be used to discriminate those cell type.

Der volle Inhalt der QuelleTo enhance the production conditions for cultured epidermal autografts (CEA) for large burns, we sought to study the in vitro effect of a low oxygen level on epidermal growth. We tested this parameter on CEA grown on murin feeder cells (Green's method) as well as human feeder cells. We first could evidence that the optimal feeder density depended on the oxygen level. A feeder density made optimal at 20% 02 could prove inhibitory on keratinocyte growth at 3% 02. At their respective best feeder densities, low oxygen level (3%) led to an average 4,2 fold increase in keratinocyte yield for a same arrest day as compared with 20% culture. This effect proved to be stable on several successive passagings, showing the increase in proliferation did not take place at the expense of tell self renewal. Keratinocytes grown at a low oxygen level kept their ability to form a stratifying epidermis on an in vivo NOD/SCID mouse excisional model. In parallel, the increase in proliferation was also observed when keratinocytes were cultured on human feeder cells, bone marrow mesenchymal stroma' cells and dermal fibroblasts. This effect of a low oxygen tension on keratinocytes appears to be partly direct, as the growth rate of HaCat feederless keratinocytes was enhanced at 3% vs 20% 02. It is also partly an indirect effect, as conditioned medium from murin feeder cells cultured in hypoxia has a more pronounced positive effect on keratinocyte growth than its normoxic counterpart. These preliminary resuits could lead to the modification on the culture protocol currently in use for the majority of CEA grafts for large burns. The expected benefits for the patients, beyond slightly shortening culture time, would include salvaging abortive cultures and bringing less differentiated keratinocytes, a parameter linked with a decrease in fibrotic evolution on murin models
Bouhlel, Wafa. „Procédé d'encapsulation à base d'hydrogels pour le développement de micro-tissus cellulaires“. Thesis, Sorbonne université, 2018. http://www.theses.fr/2018SORUS414.
Der volle Inhalt der QuelleThis thesis concerns the improvement of a hydrogel encapsulation process for three-dimensional cell culture. Submillimetric capsules are formed via high speed co-extrusion of macromolecules solutions, thereby forming a compound jet. The drops resulting from the fragmentation of the jet have a core/ shell type geometry where shell is composed of alginate. This layer is then solidified after immersion in a gelling bath. The use of biological materials required the implementation of a sequential injection system to manipulate small volumes, less than 1 mL. This approach is then accompanied by a longitudinal variation of the concentration of the suspended particles flowing in the injection tube. This dispersion can be inhibited by adding air bubbles at each end of the sample to segment it. A destabilization of the suspension initially homogeneous is observed when liquid inertia comes into play at the particle’s scale. These micrometric particles induce a flapping motion and jet speed fluctuations causing the coalescence of the drops and thus a size polydispersity. Finally, a collagen hydrogel, which mimics an extracellular matrix, has been implemented in the capsule’s core to promote adhesion of epithelial cells forming intestine and bile ducts. Within this matrix, the cells form a polarized and functional epithelium. The formation of these collagen capsules required the formulaiton of the collagen solution compatible with the process and the physiological conditions of the cells
