Abstract

Microorganisms participate in biological processes as long before man discover the possibilities for its systematic use. The production of compounds with pharmacological importance from these microscopic beings is well studied since the discovery of Penicillin. Currently, genomic analyzes have provided numerous new Natural Products from microorganisms. Therefore, this work aims to analyzing Burkholderia genomes using specific algorithms to create profiles, such as, antibiotic resistance profiles. These profiles will provide candidates for metabolic induction in a model micro-organism of the genus Burkholderia, the species B. thailandensis. Microorganisms of the class ²-Proteobacteria are emerging as sources of compounds of industrial and/or pharmacological interest where most of these Natural Products were discovered from genomic analyzes. A classic example is the discovery of teixobactin through genomic studies in Eleftheria terrae, a ²-Proteobacteria representative. In this project, bioinformatics analyzes will guide the culture media composition for carbon- and nitrogen-sources using platforms for metabolism prediction, for example, KEGG platform. The metabolic inducer concentration and the recognition of promising metabolic profiles will be determined by comparison with the standard culture media optical density (with no compounds from genomic analysis) via GC-MS, HPLC and dereplication. The discovery of new compounds will be bioguided by activities from extracts and partitions against pathogenic micro-organisms by crossing all results in dynamic networks. It is believed that rational and modern strategies, as taken in this project, can create strategies to avoid spending financial resources and save time discovering new Natural Products that could act as antibiotic agents.
