1. Construção de biblioteca metagenômica e prospecção de genes para a síntese de polihidroxalcanoatos / Metagenomic library construction for PHA synthase screening
Os microrganismos constituem dois terços da diversidade biológica na Terra, no entanto, muitos deles não podem ser cultivados por técnicas tradicionais. Portanto, o acesso a esta diversidade tem sido feita através da utilização de técnicas independentes de cultivo. Diante deste panorama, a metagenômica apresenta-se como uma alternativa, pois dispens

2. The Composition a evaluate the polymer biodegradable produce for Burkholderia sacchari with the different substrates / Avaliação da composição de polímeros biodegradáveis produzidos por Burkholderia sacchari a partir de diferentes substratos
The bacterial production of polyesters belonging to the polyhydroxyalkanoate family (PHA) has generated biodegradable, biocompatible and environmentally friendly new materials. Properties and applications of PHA depend on monomer composition, which is dependent both on the substrate available and the metabolic apparatus of the PHA-producing microorganism. Bu

3. Substrate specificities of bacterial polyhydroxyalkanoate depolymerases and lipases: bacterial lipases hydrolyze poly(omega-hydroxyalkanoates).
The substrate specificities of extracellular lipases purified from Bacillus subtilis, Pseudomonas aeruginosa, Pseudomonas alcaligenes, Pseudomonas fluorescens, and Burkholderia cepacia (former Pseudomonas cepacia) and of extracellular polyhydroxyalkanoate (PHA) depolymerases purified from Comamonas sp., Pseudomonas lemoignei, and P. fluorescens GK13, as well

4. Metabolic Engineering of Poly(3-Hydroxyalkanoates): From DNA to Plastic
Poly(3-hydroxyalkanoates) (PHAs) are a class of microbially produced polyesters that have potential applications as conventional plastics, specifically thermoplastic elastomers. A wealth of biological diversity in PHA formation exists, with at least 100 different PHA constituents and at least five different dedicated PHA biosynthetic pathways. This diversity

5. Poly(3-Hydroxyvalerate) Depolymerase of Pseudomonas lemoignei
Pseudomonas lemoignei is equipped with at least five polyhydroxyalkanoate (PHA) depolymerase structural genes (phaZ1 to phaZ5) which enable the bacterium to utilize extracellular poly(3-hydroxybutyrate) (PHB), poly(3-hydroxyvalerate) (PHV), and related polyesters consisting of short-chain-length hxdroxyalkanoates (PHASCL) as the sole sources of carbon and en
