1. Caracterização de linhagens bacterianas isoladas da biodiversidade brasileira quanto à produção de biopolímeros. / Characterization of brazilian biodiversity isolated bacterial strains on the production of biopolymer.
O lixo urbano tem sido apontado como um dos maiores poluentes ambientais. O lixo plástico chega a representar 20% do volume do lixo doméstico. Como alternativa aos plásticos petroquímicos, produtos plásticos menos agressivos ao meio ambiente e mais biodegradáveis têm sido estudados, entre eles os polihidroxialcanoatos (PHA). Os PHA são poliésteres b

2. A Novel Phenanthrene Dioxygenase from Nocardioides sp. Strain KP7: Expression in Escherichia coli
Nocardioides sp. strain KP7 grows on phenanthrene but not on naphthalene. This organism degrades phenanthrene via 1-hydroxy-2-naphthoate, o-phthalate, and protocatechuate. The genes responsible for the degradation of phenanthrene to o-phthalate (phd) were found by Southern hybridization to reside on the chromosome. A 10.6-kb DNA fragment containing eight phd

3. Characterization of the Phd Repressor-Antitoxin Boundary
The P1 plasmid addiction operon (a classic toxin-antitoxin system) encodes Phd, an unstable 73-amino-acid repressor-antitoxin protein, and Doc, a stable toxin. It was previously shown by deletion analysis that the N terminus of Phd was required for repressor activity and that the C terminus was required for antitoxin activity. Since only a quarter of the pro
