Повний текст джерелаClostridium cellulolyticum is a strict anaerobe, cellulolytic bacteria. It produces multienzymatic complexes, called cellulosomes, which are able to efficiently degrade the plant cell wall polysaccharides. Cellulolytic bacteria, including C. cellulolyticum do binds to cellulose since early growth stage. For most of the studied cellulolytic bacteria, adherence to cellulose seems to be mediated by their cellulosomes. However, molecular factors involved in C. cellulolyticum adherence to cellulose remain unknown.My Ph.D. aimed to implement different but complementary strategies to study adhesion and colonization of cellulose fibers by C. cellulolyticum and to identify the molecular mechanism(s) by which the bacteria bind to cellulose. In order to identify some proteins encoding genes involved in adhesion, I firstly developed random mutagenesis and isolated two adhesion deficient mutants. I also used a targeted mutagenesis tool to inactivate some candidate genes.My studies highlight C. cellulolyticum adheres with both high specificity and affinity to cellulose. Colonization of cellulose fibers by C. cellulolyticum forms a mono-layer of segregated cells on cellulose surface and may occur through cycles of adhesion-release-re-adhesion to substrate. Inactivation of the CipC encoding gene led to a short decrease of the mutant strain's adherence level. This result suggests some other proteins may be involved in C. cellulolyticum adhesion to cellulose. Finally, I studied HycP, a produced and secreted CBM3 encoding protein of unknown function. HycP is a unique protein among databases and may have a phagic origin

Повний текст джерелаLignocellulosic materials have a high energy potential and are abundant, especially in municipal solid waste and their methanization is a promising waste-to-energy bioprocess. However, owing to their highly complex and heterogeneous structure, they are recalcitrant to anaerobic conditions and the use of pre-treatments is usually required to improve their biodegradation yields. Besides, lignocellulose colonization by cellulolytic microorganisms is a key step for an efficient biodegradation. In this context, the PhD work aimed to better understand the factors affecting waste colonization, to establish the link between lignocellulosic waste colonization and its biodegradation efficiency and to characterize more precisely the mechanisms and interactions within the biomass. A transversal approach was developed, combining cultures of model pure strains and lab-scale methanization microcosms with a complex biomass. Integrated approaches were applied to these studies, combining high-throughput analyses (metagenomics/(meta) proteomics), physico-chemical monitoring of bioconversion and finally physico-chemical characterization of substrates. The main results highlight the important role of lignocellulosic materials chemical and micro-and macro -structural features for their recalcitrance, their biodegradation efficiency and the response of the microbial compartment. The first global quantitative proteomic study on the cellulolytic model Clostridium cellulolyticum was conducted. Results showed an increased biodegradation rate of the facial tissue compared to cotton. This enhanced biodegradation was associated to a particular metabolic profile, a faster and more extensive colonization and finally a quantitative modulation of the cellulasic system. On the other hand, study of lignocellulosic waste methanization confirmed the good agreement between this more realistic system and the above-described model system. It also provided new information about the effects of substrate on microbial community structure. Noticeably, Bacteroidia members predominated in the presence of tissue and a high proportion of Spirochaetes members was observed in the presence of cotton. Finally, study of the effects of wheat straw and cardboard dry grinding revealed the limitations of these pretreatments on biodegradation efficiency. Main key points were a moderate positive effect of wheat straw fine grinding, and the sensitivity of the microbial communities to substrate surface characteristics, as evidenced by the emergence of different microbial communities according to the applied mechanical pretreatment. In conclusion, this work brings new perspectives to the study of lignocellulosic waste recalcitrance by addressing both the structural, functional and ecological aspects. These results contribute to the core fundamental knowledge on bioprocesses. They confirm that the lignocellulosic materials are specific among non-hazardous waste and require the implementation of adapted specific processes

Повний текст джерелаAu cours des deux dernières décennies, une grande quantité de recherches ont portées sur les fibres de cellulose naturels, car ils sont «verts» et de matières premières renouvelables. Récemment, la science des nanomatériaux a attiré l'attention en raison de la gamme grande surface et les propriétés uniques des nanoparticules. La cellulose est en train de devenir un matériau important dans la science des nanomatériaux, à la demande croissante de matériaux écologiques. Dans ce travail, un nouveau procédé de préparation de cellulose nanofibres (CNF) est présenté. Cette méthode contient un maximum de trois étapes d'oxydation: oxydations au periodate, au chlorite et au TEMPO (2,2,6,6-tétraméthylpipéridinyle-1-oxyle). Les deux premières étapes d'oxydation sont étudiées dans la première partie de ce travail. La pâte de cellulose a été oxydée à des degrés divers par un à deux étapes d'oxydation au periodate de sodium, suivi par le chlorite de sodium. Les produits oxydés peuvent être séparés en trois fractions différentes. Le ratio de la masse et le contenu de charge de chaque fraction ont été déterminés. La morphologie, la distribution de la taille et l'indice de cristallinité de chaque fraction ont été mesurés par l'AFM, DLS et XRD, respectivement. Dans la seconde partie de ce travail, des CNF ont été préparés et modifiés dans diverses conditions, y compris (1) l'introduction de diverses quantités de groupes aldéhyde sur les CNF par oxydation au periodate, (2) les groupes carboxyle sous forme de sodium sur les CNF ont été convertis à leur forme acide par traitement avec un type d'acide résine échangeuse d'ions; (3) ces CNF ont été réticulés de deux manières différentes en employant dihydrazide adipique (ADH) en tant que cross-linker et soluble dans l'eau 1-éthyl-3-[3- (diméthylaminopropyl)] carbodiimide (EDC) comme agent activateur de carboxyle. Les films ont été fabriqués avec ces suspensions de CNF modifiés par filtration sous vide. Les propriétés optiques, mécaniques et la thermo-stabilité de ces films ont été étudiées par spectrométrie UV-visible, essai de traction et de l'analyse thermogravimétrique (TGA). Les taux de transmission de vapeur d'eau (WVTR) et l'angle de contact de l'eau (WCA) de ces films ont également été étudiés.

Повний текст джерелаCellulose wird u.a. durch ihre Molmassenverteilung charakterisiert, deren Ermittlung ein polymeranaloges Verfahren zur molekulardispersen Auflösung des Polymers erfordert. Hierfür sind die Direktlösung, die Nitrierung und die Carbanilierung in Gebrauch. Bei allen Prozessen kann es zum Abbau der Polysaccharidketten kommen, wobei diesen Prozessen wenig Beachtung geschenkt wurde. In der Arbeit wird gezeigt, daß der Abbau bei der Carbanilierung in Pyridin durch Beta-Eliminierung an vorhandenen Carbonylgruppen erfolgt. Die Carbanilierung in DMSO fällt stets stärker aus als bei Einsatz von Pyridin und umfasst die Prozesse Oxidation nach dem Pfitzner-Moffatt-Mechanismus und anschließende Beta-Eliminierung an den neu gebildeten Carbonylgruppen. Dies wird durch Untersuchungen an Modellsystemen und am Polymer herausgearbeitet. Carbonylgruppen an Cellulose werden durch die Umsetzung mit Phenylisocyanat maskiert, was an Modellverbindungen gezeigt wurde (Bildung von Endioldicarbanilaten und carbanilierten Halbacetalen). Ihre Bestimmung in Cellulosecarbanilaten ist daher nicht möglich. Die Abtrennung von niedermolekularen Nebenprodukten der Umsetzung wurde optimiert. Der Einfluss der Vorbehandlung und Voraktivierung von Celluloseproben auf die Vollständigkeit der Umsetzung wurde eingehend untersucht. Es wird ein Standardverfahren zur Carbanilierung von Cellulose angegeben

Повний текст джерелаTo reduce the extensive environmental impact of the textile industry, new methods for textile recycling are being developed. Today, cotton-based fabric is recycled by Renewcell at their facility in Kristinehamn. The recycled product, Circulose®, is a dissolving pulp that can be used to spin new viscose fibers, which in turn can be used to make new clothes. The present work is a feasibility study on the possibility of optimizing Renewcell's recycling process. The work includes an optimization of the pulp process, which results in a more efficient process with a reduced consumption of process chemicals.

Повний текст джерелаBiologiskt nedbrytbara polymerer börjar framträda som en lösning för det ökade behovet avmiljövänliga material. Samtidigt så växer intresset för lättare och starkare strukturer. I denna rapport tar vi upp produktionsstegen för att uppnå nanofibril komposit cellulosa fibrer (CNF), med hjälp av en ny grön polymerisation mest känd som ”wet spinning”. Med denna nya teknik så behövs inte dem traditionella miljöfarliga viskosprocesserna och man producerar biologiskt nedbrytbara CNF filaments med intressanta mekaniska egenskaper. Denna metod appliceras sen för att producera en komposit som aldrig setts innan. CNF fibrer som består av tre lager ”head-extruder”. För att få fibrer med ledningsförmåga så mixas PEDOT/PPS med CNF för att producera ”in-situ komposit fibrer”. Svepelektronmikroskop (SEM), atomkraftsmikroskopi och töjningstester används för att karaktärisera egenskaperna av fibrerna.

Повний текст джерелаIn recent years, with the excessive use of non-renewable resources on the earth, the ecological environment has been seriously affected. At the same time, humans began to worry about running out of resources. Therefore, it is necessary to develop environmentally friendly renewable resources. Cellulose-based material is an excellent choice. Commonly, cellulose-based material consists of reinforcement (cellulose fiber) and matrix (polymer or metal). However, the compatibility between cellulosic material and polymer matrix should be considered. In general, the compatibility between them is poor. In this project, several methods to improve the compatibility between the cellulose material and polymer matrix were studied. Two cellulosic materials (microcrystalline cellulose (MCC) and cellulose oxalate (COX)) were treated with different modification methods to improve the compatibility and interfacial interaction between the cellulosic material and polymer matrix. Ball milling, using water as a dispersing agent, using oleic acid to esterify cellulose fiber for different reaction times (6 h, 18 h, and 48 h), and using different concentrations (1% and 2%) of maleic anhydride grafted polypropylene (MAPP) as compatibilizers were applied to improve the compatibility between cellulose fiber and polymer matrix. To produce the composite specimens, extrusion and injection molding were utilized. Tensile testing was done to test the mechanical properties of the specimens. Contact angle (CA), scanning electron microscope (SEM), Fourier Infrared Spectrometer (FTIR), X-ray diffraction (XRD) were also performed on the various cellulose powders as characterization methods. According to the result of tensile testing, COX samples with 1% MAPP as compatibilizer, showed the highest tensile strength and Young’s modulus of all the composite samples produced in this master thesis. Using MAPP as a compatibilizer shows a better result than using other methods to improve the compatibility between hydrophilic MCC/COX surface and hydrophobic PP matrix. The use of MAPP as a compatibilizer should be prioritized when producing composite materials.

Повний текст джерелаCellulose, one of the most abundant biopolymers, is used in this PhD work in its nanofibrillated form, 2-5 nm in diameter and microns long, to prepare sustainable nanomaterials. Both positively and negatively charged microfibrillated celluloses (MFC) are assembled in these nanomaterials using the versatile Layer by Layer (LbL) assembly methods: dipping, spray assisted-deposition and spin-assisted deposition. A brief comparison between the MFC based LbL assembled films and the standard polymeric LbL films is carried out. Thedifferences between the two species are related to the fibrillar form of cellulose. MFC behaves like rigid anisotropic nano-objects. MFC LbL assembled films are then integrated in separation membranes between active polymeric separation layers and a mechanically stable porous support to improve the flux through these membranes. MFC LbL assembled films are also coated on cellulosic aerogels to improve the wet stability of these aerogels. In both cases, results were encouraging and showed a proof of concept

Повний текст джерелаEste trabalho investiga a variabilidade composicional e nanoestrutural de celuloses isoladas de plantas e o seu impacto na variabilidade na produção de nanocristais de celulose. Um conjunto variável de celuloses isoladas de plantas foi gerado a partir de uma série de matérias-primas (fibra de coco, sisal, serragem de eucalipto, serragem de pinheiro, casca de cana e miolo de cana), aplicando uma série de processos de isolamento de celulose (hidrotérmico, alcalino, hidrotérmico + alcalino e acetosolve) e adicionando celuloses comerciais (polpa kraft de eucalipto, polpa para dissolução e celulose microcristalina) como materiais de referência. As características nanoestruturais foram avaliadas por termoporometria calorimétrica, difração de raios X e isotermas de sorção de umidade. A composição foi avaliada por análise química húmida padrão e os conhecimentos sobre grupos funcionais foram obtidos por espectroscopia de infravermelhos. Os nanocristais de celulose foram produzidos por hidrólise ácida com ácido sulfúrico e caracterizados por microscopia de força atômica e difração de raios-X. Os parâmetros medidos das celuloses isoladas foram distribuídos, demonstrando que poderíamos alcançar um conjunto altamente diversificado de substratos. Correlações significativas entre as variáveis medidas foram observadas em todo o conjunto amostral, indicando possíveis relações multivariadas imprevistas entre as características da celulose. Por exemplo, poderíamos demonstrar que a monocamada de hidratação de celulose é determinada tanto pelo conteúdo de hemiceluloses (parâmetro de composição) quanto pela largura do cristal de celulose (parâmetro estrutural). Os nanocristais de celulose foram produzidos com sucesso, embora em alguns casos, como nas polpas acetosolve, as condições ácidas fossem muito agressivas e oxidassem os substratos. Finalmente, algumas correlações quantitativas foram observadas entre os parâmetros dos substratos de celulose e os nanocristais de celulose resultantes. Estes resultados fornecem as primeiras dicas sobre como a variabilidade nanoestrutural da celulose isolada pode influenciar os nanocristais de celulose produzidos a partir deles.
