1. Isolation and purification of bromelain from waste peel of pineapple for therapeutic application
The aim of this work was to isolate and purify bromelain extracted from the pineapple peel by ammonium sulfate precipitation (40-80%), followed by desalting and freeze-drying with a 75% activity recovery and 2.2 fold increased specific activity. Ion exchange chromatography on DEAE-Sepharose was able to separate the polysaccharides from the enzyme, which was

2. Evaluation of Antimicrobial Activity of Glucose Oxidase from Aspergillus niger EBL-A and Penicillium notatum
This work aimed to study the production and purification of glucose oxidase by Aspergillus niger and Penicillium notatum using corn steep liquor as the substrate and evaluate its antimicrobial activity for use in pharmaceutical and food industries. The enzyme was purified by ammonium sulfate precipitation (60-85%), DEAE-cellulose ion exchange and Sephadex G-

7. Modelagem da coalescência em sistemas bifásicos polidispersos usando balanço populacional e técnicas de CFD - aplicação à dessalgação de petróleo. / Modeling of the coalescence in polydisperse two-phase systems by means of population balance and cfd techniques - application to oil desalting.
O balanço populacional é um método comprovado de se aumentar a previsibilidade do comportamento de um sistema multifásico, e sua utilização em conjunto de técnicas de CFD tem sido cada vez maior pelo desenvolvimento constante de ambas as tecnologias. Este trabalho apresenta o equacionamento genérico do balanço populacional para sistemas bifásicos c

8. Purification of a 19-kDa pore-forming cytolysin from the sea anemone Heteractis magnifica
Pore-forming cytolysins of 19 kDa from sea anemones present a remarkable cytolytic property. In the present work, a purified 19-kDa cytolysin was obtained from the sea anemone Heteractis magnifica. The purification steps involved ammonium sulfate precipitation and subsequently desalting by dialysis against 10 mM sodium phosphate buffer (pH 7.4), followed by

9. Characterization, purification and phylogenetic analysis of a cytolysin from the sea anemone Heteractis magnifica of the Indian Ocean
It is well established that sea anemones comprise a rich source of cytolytic toxins. The present study reports the isolation and characterization of a cytolysin obtained from the sea anemone Heteractis magnifica collected in the Andaman Islands of the Indian Ocean. The crude extract was screened for hemolytic activity by a blood agar plate method and a 6-mm

10. Process analysis of crude oil desalting - water uses optimization. / Análise do processo de dessalgação de petróleo - otimização do uso de água.
The aim of this work is the study of the reduction of water consumption in petroleum desalting processes. The study of the attraction forces acting on the droplets was necessary to know how the emulsion water/oil is separated. A mathematical model based upon these forces was built to calculate the time between each droplets collision and to establish criteri

11. Latex constituents from Calotropis procera (R. Br.) display toxicity upon egg hatching and larvae of Aedes aegypti (Linn.)
Calotropis procera R. Br. (Asclepiadaceae) is a well-known medicinal plant with leaves, roots, and bark being exploited by popular medicine to fight many human and animal diseases. This work deals with the fractionation of the crude latex produced by the green parts of the plant and aims to evaluate its toxic effects upon egg hatching and larval development

12. Miotoxinas PLA2 "like" de Bothrops pirajai : caracterização molecular e funcional
The genus Bothrops comprises severaI species, which are widely distributed in South and North America. Among the bioactive proteins from Bothrops venoms, the phospholipase A2(PLA2,E.C.3.1.14) and PLA2-likemyotoxin are outstanding as their major components. Phospholipase A2Sare calcium-dependent enzymes which hydrolyze the 2 ester bonds of 1,2 diacyl-3sn phos
