Objetivo New antibiotics are urgently needed to combat persistent, emerging and re-emerging infectious diseases. Historically, microbial natural products have been a prolific source of antibacterials, and the screening of microbial extracts has yielded many classes of antibiotics. However, this approach was largely abandoned by big pharma because of the high rates of rediscovery of known antibiotics, and the general belief that there were very few new antibacterials to be discovered from microbial natural products.Sequencing of bacterial genomes has changed that view completely. In many bacteria there are far more gene clusters directing the biosynthesis of antibiotic-like metabolites than natural products known to be produced by the organism. These so-called “cryptic” gene clusters (cryptic because their metabolic products are not known) are often silent (not expressed) under standard laboratory conditions, and can represent up to 80-90% of the secondary metabolite gene clusters in some bacteria.In recent years we have witnessed an increased in the employment of cocultures (i.e. cocultivation of more than 1 microorganism) as a strategy to discover new natural products by exploiting cross-communication processes mediated by diffusible signalling molecules.In this project we will carry out an in-depth study of the capacity of this strategy to discover new antibacterials from microbial metabolites. Objectives: a) Cocultivation of microorganisms from an actinomycete-based microbe collection employing a specifically designed dual fermentation system. b) Antibiosis screening of the obtained microbial extracts using modern high-throughput technologies; identification of active extracts c) LC-MS based chemical dereplication of active extracts using in-house and external natural product databases; identification of promising extracts d) Scale-up of active extracts, bioactivity-guided fractionation process to purify active compounds; structural elucidation of active compounds Ámbito científico natural sciencescomputer and information sciencesdatabasesnatural sciencesbiological sciencesmicrobiologybacteriologymedical and health scienceshealth sciencesinfectious diseasesmedical and health sciencesbasic medicinepharmacology and pharmacypharmaceutical drugsantibioticsnatural sciencesbiological sciencesgeneticsgenomes Programa(s) FP7-PEOPLE - Specific programme "People" implementing the Seventh Framework Programme of the European Community for research, technological development and demonstration activities (2007 to 2013) Tema(s) FP7-PEOPLE-2011-CIG - Marie-Curie Action: "Career Integration Grants" Convocatoria de propuestas FP7-PEOPLE-2011-CIG Consulte otros proyectos de esta convocatoria Régimen de financiación MC-CIG - Support for training and career development of researcher (CIG) Coordinador FUNDACION CENTRO DE EXCELENCIA EN INVESTIGACION DE MEDICAMENTOS INNOVADORES EN ANDALUCIA Aportación de la UE € 100 000,00 Dirección AVDA DEL CONOCIMIENTO 3 18100 Armilla Granada España Ver en el mapa Región Sur Andalucía Granada Tipo de actividad Research Organisations Contacto administrativo Gerald Bills (Dr.) Enlaces Contactar con la organización Opens in new window Sitio web Opens in new window Coste total Sin datos
