1. Production and extraction of clavulanic acid from Streptomyces spp. by extractive fermentation using aqueous two-phase system / Produção e extração de ácido clavulânico de Streptomyces spp. por fermentação extrativa utilizando sistemas de duas fases aquosas
Clavulanic acid (CA) is a potent inhibitor of β-lactamases used in the medical field. Alternative methods, economic and simple purification are of great interest. This PhD project aims to produce and extract clavulanic acid of Streptomyces spp. By extractive fermentation using aqueous two-phase system (ATPS) - Polyethylene glycol (PEG)/phosphate salts.

2. Produção de celulases e xilanases por Penicillium echinulatum em processo submerso utilizando biorreatores com agitação mecânica e airlift de circulação interna
Cellulolytic enzymes have many uses, particularly in the food, textile, and paper industries. However, their major potential use is in the hydrolysis of cellulose a component of lignocellulosic residues for ethanol fuel production. Among the cellulase-producing microorganisms, mutants of the Trichoderma genus are the most studied and most widely used in the

3. Otimização das condições de cultivo de Erysipelothrix rhusiopathiae para produção de vacina contra erisipela suína
Swine erysipelas is one of the diseases responsible for the great economic losses in swine-producing areas of the world. The bacteria Erysipelothrix rhusiopathiae is the causative agent of erysipelas, and the vaccines currently available for prevention of this disease are produced with the whole broth culture containing the inactivated microorganism or its l
