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 ...
Isomerização de n-hexano sobre Pt-NiHUSY empregando zeolita com alto teor de Al.
(Universidade Federal de São Carlos, 2005-08-03)
The isomerization reactions of linear alkanes are very important to petrochemical industries due to the isomer products in reaction possess high octane number. The majority of the literature articles involves the job ...
Lipase “whole-cell” de Streptomyces clavuligerus : produção, caracterização e aplicação em meio orgânico
(Universidade Federal de São Carlos, 2016-08-25)
Cell-associated lipases have been considered biocatalysts economically advantageous because
they are produced at low cost, avoiding further recovery or purification steps. Few studies
regarding Streptomyces clavuligerus ...
Estudo do pré-tratamento hidrotérmico e hidrólise enzimática da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2016-04-08)
The complex cell wall structure of lignocellulosic biomass makes pretreatment one of the most
relevant 2G ethanol production process steps due to the difficulty of hydrolyzing lignocellulose
to fermentable sugars and the ...
Influência das cargas eletrostáticas na filtração de partículas em meios filtrantes de fibra de vidro
(Universidade Federal de São Carlos, 2019-04-30)
Currently, in the gas filtration processes, the presence of electrostatic charges in the particles has been shown to contribute positively to the performance of the filter medium. Due to its high competitiveness in the ...
Oxidação de CO sobre catalisadores de Co e/ou Mn modificados com Mo e suportados em SBA-15 – Efeito do método de preparação e da presença de vapor de água e dióxido de enxofre na atividade catalítica
(Universidade Federal de São Carlos, 2016-08-25)
The increasing demand for oil and oil derived products contributed to the alarming increase in the gaseous pollutants emissions in general and mainly contributed to the increase in carbon monoxide (CO) emissions in the ...

(Universidade Federal de São Carlos, 2015-08-27)
The genus Salmonella spp. has been extensively investigated because these
bacteria are important pathogens that frequently cause severe diseases and gastrointestinal
infections in humans and animals. Moreover, in recent ...
Otimização descentralizada coordenada aliada a estratégias de controle plantwide para o controle de processos químicos
(Universidade Federal de São Carlos, 2016-07-08)
Chemical plants are increasingly complex and integrated with recycle streams promoting
energy integration and increasing process yield. This results in a complex dynamic
behavior which can interfer in control systems ...
Análise da secagem convectiva de folhas de manjericão (Ocimum basilicum L.)
(Universidade Federal de São Carlos, 2013-03-19)
Convective drying of leaves involves heat and mass transfer in packed-beds of deformable material, since the leaves shrink significantly when the moisture is removed. Therefore, the packing structure changes over time, and ...
Síntese da zeólita Beta usando planejamento experimental e emprego na isomerização do n-hexano
(Universidade Federal de São Carlos, 2012-09-14)
This work aimed to apply the Design Of Experiment (DOE) methodology as an auxiliary tool to evaluate the conditions of synthesis of the aluminum-rich zeolite Beta. Bimetallic catalysts with 50% platinum and 50% nickel ...
