(Universidade Federal de São Carlos, 2005-11-25)
Vibro-fluidized beds with inert particles as fluidizing medium have been appearing as an innovative technique for drying of suspensions and pastes. Aiming to contribute for the comprehension of phenomena involved in such ...
Influência das condições de alimentação de glicerol e ornitina na produção de ácido clavulânico por Streptomyces clavuligerus
(Universidade Federal de São Carlos, 2008-03-26)
The clavulanic acid (CA) is a powerful inhibitor of β-lactamases, enzymes that clives the β-
lactam ring of penicillins and cephalosporins, inactivating these compounds. CA is
traditionally produced by Streptomyces ...
