1. Investigation of hydrodynamic parameters in a novel expanded bed configuration: local axial dispersion characterization and an empirical correlation study
Study of liquid behavior in an expanded bed adsorption (EBA) system is important for understanding, modeling and predicting nanobioproduct/biomolecule adsorption performance in such processes. In this work, in order to analyze the local axial dispersion parameters, simple custom NBG (Nano Biotechnology Group) expanded bed columns with 10 and 26 mm inner diam

2. Comparative study of hydrodynamic behavior of liquid expanded bed adsorption: mathematical and short-cut methods
Liquid fluidized/expanded bed adsorption (LF/EBA) is a novel chromatography technique for capturing target biomolecules directly from crude feedstock in downstream processing. To widely extend the LF/EBA technology in biological industries, a better understanding of the expanded-bed behavior is necessary to maximize its efficient applications. In this study,

3. Expanded bed adsorption of bromelain (E.C. 3.4.22.33) from Ananas comosus crude extract
This work focuses on the adsorption of Bromelain in expanded bed conditions, such as the adsorption kinetics parameters. The adsorption kinetics parameters showed that after 40 minutes equilibrium was achieved and maximum adsorption capacity was 6.11 U per resin mL. However, the maximum adsorption capacity was only determined by measuring the adsorption isot

4. 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

5. 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

6. Recuperação e purificação de enzimas usando adsorção em leito expandido
This work deals with the application of Expanded Bed Adsorption (EBA) to recovery and purify enzymes. Model proteins, lisozyme and bovine serum albumin (BSA), as well as some enzymes, glyceraldehyde 3-phosphate dehydrogenase (G3PDH) from baker s yeast, xylanase (from a commercial extract) and chitosanase from Bacil/us cereus were used to study the EBA backgr
