16. Separação da lisozima, conalbumina e ovalbumina presentes na clara do ovo: aspectos tecnológicos e termodinâmicos / Separation of lysozyme, conalbumin and ovalbumin from the egg white: technological and thermodynamic aspects
Neste trabalho, estudou-se a integração dos processos de cromatografia de adsorção em leito expandido (ALE) e extração líquido-líquido por sistemas aquosos bifásicos (SAB) para a separação e purificação das proteínas da clara do ovo (ovalbumina, conalbumina e lisozima). A ALE foi empregada para a separação de duas frações protéicas da clar

17. Purificação e caracterização de bromelina a partir do extrato bruto de Ananas comosus por adsorção em leito expandido / Purification and characterization of bromelain, from crude extract of Ananas comosus, using expanded bed adsorption
Bromelain are extracted from Ananas comosus infrutescence, and are used in food industry, as a meat softener, and pharmaceutical industry, as well. Bromelain are presented in the early stages of fruit development, however, their levels increase quickly, remaining high until the maturation. Expanded Bed Adsorption (EBA) is a chromatography technique for separ

18. Adsorção de glicomacropeptídeo por interação hidrofóbica em leito expandido / Adsorption of the glicomacropeptide by hydrophobic interaction in expanded bed
Neste trabalho, foi estudado o processo de adsorção da proteína glicomacropeptídeo (GMP) proveniente do soro de queijo, em cromatografia de interação hidrofóbica,variando-se as condições de temperatura e a concentração de sal. Foi usada a calorimetria de titulação para conduzir uma análise termodinâmica do processo. Obtiveram-se as curvas de r

19. Reator de leito expandido em escala plena com zonas anaeróbia e aeróbia sobrepostas: remoção conjunta de matéria orgânica e nutrientes e estudo do comportamento microbiológico do biofilme, por respirometria e microsensor de OD / Full scale expanded bed reactor with overlaid anaerobic and aerobic zones: joint removal of organic matter and nutrients and the study of microbiological biofilm behavior and DO microsensor
The current research aimed the development of a 159 M POT.3total volume biological reactor, with a expanded and partially aerated granular coal bed (activated and anthracite), to promote organic matter and nutrients (N and P) removal from wastewater due to the maintenance of anaerobic and aerobic environments, stratified throughout the height of the reactor

20. Characterization and recovery of alfa and beta amylases enzymes by expanded bed adsorption systems / Caracterização e recuperação das enzimas alfa e beta - amilases em sistema de adsorção em leito expandido
Aiming to development of new technologies, in this work a and b-amylases recovery from maize (Zea mays) malt by expanded bed adsorption (EBA) was studied in order, to aggregate value to the maize culture which is diffused into our Country. Thus, the optimization of the manufacture steps of maize malt, since the germination (changing the time) until the dryin

21. Coagulation/precipitation of effluents from anaerobic expanded bed reactor and activated sludge system preceded by UASB reactor, with particle removal by sedimentation or flotation / Coagulação/precipitação de efluentes de reator anaeróbio de leito expandido e de sistema de lodo ativado precedido de reator UASB, com remoção de partículas por sedimentação ou flotação
The anaerobic reactors of modern conception (e.g., UASB and RALEx) remove from 65 to 75% of sanitary wastewater organic matter with relatively low construction, operation, and maintenance costs, in comparison with conventional aerobic processes. Nevertheless, that reactors are usually little efficient in nutrient removal and their effluents may present relat

22. Concentration of alpha-lactalbumin from cow milk whey through expanded bed adsorption using a hydrophobic resin
The design of novel applications for the use of new high-density adsorbents in the direct recovery of proteins requires analysis of the fluid dynamics and mass transfer characteristics of the column used with the solid-liquid system. In this article we describe the operating parameters related to the use of a high-density, hydrophobic resin (Streamline® Phe

23. Adsorption of the inulinase from Kluyveromyces marxianus NRRL Y-7571 on Streamline® DEAE resin
The enzyme inulinase is used to produce oligosaccharides and fructose, with up to 95% fructose in a single stage of inulina hydrolysis. With in the aim to purify the enzyme, studies on the conditions of enzyme adsorption in an expanded-bed column were conducted using phosphate and tris-HCl buffers. The inulinase used in this work was obtained from Kluyveromy
