| Associated scholarship(s): | 16/24290-6 - Analysis of transcriptional profile from Pseudomonas sp. LFM046 and theirs recombinants producing biopolymer / polyhydroxyalkanoates from glucose based on DNA Microarray and RNA-Seq., BE.EP.PD |
Abstract Polyhydroxyalkanoates (PHAs) are biodegradable polymers with thermoplastic properties produced bymicroorganisms from renewable materials. PHAs containing medium-chain-length monomers (PHAMCL)produced by Pseudomonas sp. have a broad spectrum of use. This proposal aims genomic sequencing andannotation of a new species of Pseudomonas (LFM046) able to produce PHAMCL. Pulsed-fieldelectrophoresis also will be performed for discrimination/comparative analysis from this new species ofPseudomonas in relation to others already known, providing information about the number of chromosomes,plasmids and expected genome size. Furthermore, recombinants strains will be built presenting a controlledexpression of specific genes from the Entner-Doudoroff pathway (ED), in order to evaluate if the expressionlevel of genes from ED interferes on values of PHA yield from carbohydrates. The DNA sequencing usingnext-generation sequencers and genomic annotation of the bacteria will increase our knowledge about thegenotype - phenotype relationship that governs their metabolism. The results generated will be used to buildgenomics scale metabolic network for this strain and theirs recombinants, and to increase the knowledgeabout the metabolic pathways involved in the PHAs production and to guide future projects to thedevelopment of improved strains. | |
