Réaction en chaîne par polyméraseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Traditional identification of fur species is a problem ; without unified standards il depends significantly on the experience of the tester. In this study, we cleveloped a.method of identification of fur species by DNA barcoding based on 16S rRNA gene. 18 usuel fur species sequences of 165 rRNA gene were obtained from Genebank and primers for PCR were designed in the conserved ragions. By the optimization of experimental procedure, polymerase chain reaction (PC R) can be successfully performed with DNA isolated from fur. Sequence analyses of the -240bp production of PCR could help us to authenticate the fur species accurately. Note de contenu : - Reference materials and samples

Réaction en chaîne par polyméraseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Currently the identification of leather species is mainly via a skilled operator using optical microscopy and an extensive visual reference library. However, due to the limitations of optical microscopy and in cases where the leather surface is heavily corrected or finished, it is not always possible to accurately determine the leather species. Therefore, it is crucial to develop a reliable and easy to perform approach to overcome these limitations. In this paper, we used the unique DNA sequence present in every species to identify leather. The conversion process of making leather destroys much of the DNA present but the high copy number of mitochondrial DNA (mtDNA) in relation to nuclear DNA makes some mtDNA likely to survive and be detected via polymerase chain reaction (PCR). However, leather DNA is highly degraded and inhibitors present in the extracted DNA make successful PCR challenging. There are only a few related works reported in the literature attempting to use DNA for leather species identification and they provide limited technical details. In this study, species-specific primers for PCR were designed, conditions for DNA extraction from leather followed by PCR were optimized, and a detailed protocol was also provided. As a proof of concept, our approach demonstrated that the species of leather can be reliably detected via PCR targeting mtDNA.

Réaction en chaîne par polyméraseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hides and skins are protein based materials containing high amounts of water, which makes them a nutritionally rich media ideal for bacterial growth. Being also the essential raw materials in leather manufacture, it is vital to carefully protect them against bacterial action especially in the early wet processing stages. It is well known that bacterial action can seriously damage the fiber structure of hides and skins. Hair slip, red discoloration and grain pilling are typical examples of bacterial action can lead to damage with subsequent defects on the tanned leather. The present study identifies a new defect caused by bacteria known as "biofilm" on hides and skins. For investigation of the observed defective areas, two techniques were used : Scanning Electron Microscopy (SEM), and Real-Time Polymerase Chain Reaction (RT-PCR). The latter technique, RT-PCR, is a novel rapid method for unique detection, identification and quantification of microorganisms. The results, obtained by applying these techniques, verified the presence of "microbial biofilm" on the leather. Note de contenu : - Material

solvantsIndex. décimale : 668.4 Plastiques, vinyles Résumé : Composite films are successfully used in the packaging industry to reduce the weight of the packaging material and to increase the product shelf life. Thus, they contribute significantly to CO2 reduction. However, due to functional requirements, composite structures often use incompatible plastics, which prevent recycling in proven mechanical re-extrusion processes. Solvent-based recycling processes offer an attractive and technically mature solution to tackle the challenge. Note de contenu : - Physical dissolution of plastics from composite structures
