Transport of amino acids from milk whey by Caco-2 cell monolayer after hydrolytic action of gastrointestinal enzymes
(Food Research International, 2014-09-01) [Artigo]
The bioavailability of amino adds from milk whey protein hydrolysates was evaluated using diffusion of the substances through semi-permeable membranes (dialyzability) and transport by Caco-2 cell cultures. The hydrolysates ...
Rhamnolipid emulsifying activity and emulsion stability: pH rules
(Colloids and Surfaces B: Biointerfaces, 2011-07-01) [Artigo]
Rhamnolipids have excellent emulsifying power with a variety of hydrocarbons, aromatic compounds and vegetable oils. This paper evaluates the effect of pH ranging from 3 to 9 on the emulsifying activity and stability of ...
Effect of divalent metal ions on the activity and stability of β-galactosidase isolated from Kluyveromyces lactis
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2010-11-27) [Artigo]
In this study, it was demonstrated that β-galactosidase can be deactivated and reactivated with EDTA and divalent metal ions. The enzyme was deactivated after 20 minutes in EDTA solution. Maximal deactivation at the lowest ...
Produção de glicose e frutose por invertase de Saccharomyces cerevisiae imobilizada em suporte MANAE-agarose
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2013-06-27) [Artigo]
Invertase from Saccharomyces cerevisiae was immobilized on agarose beads, activated with various groups (glyoxyl, MANAE or glutaraldehyde), and on some commercial epoxy supports (Eupergit and Sepabeads). Very active and ...
Reuse of Cyclodextrin Glycosyltransferase through Immobilization on Magnetic Carriers
(http://dx.doi.org/10.4172/eeg.1000111, 2013) [Artigo]
CGTase from Bacillus lehensis isolated from wastewater of a cassava flour mill in the state of São Paulo, Brazil was immobilized after being partially purified using precipitation with ammonium sulfate. The partially ...
