Produção de cefamicina C por Streptomyces clavuligerus em batelada e batelada alimentada
(Universidade Federal de São Carlos, 2010-03-31)
Cephamycin C (CephC) is a natural antibiotic produced by Streptomyces clavuligerus that presents β-lactamases resistance, enzymes that clives β-lactam of antibiotics. The aim of present work was study cephamycin ...
Estudo de catalisadores de cobre suportados para a reação de oxidação preferencial do CO
(Universidade Federal de São Carlos, 2010-06-30)
The CO preferential oxidation reaction (PROX-CO) has been widely studied in last few years. Aiming H2 purification for proton-exchange membrane cells (PEMFC) use, the main role of the PROX-CO reaction should be reduce the ...
