A process for the combined recovery of pectin and phenolic compounds from apple pomace, the primary by-product of apple juice production, was developed. The process includes extraction of dried apple pomace with diluted mineral acid and adsorption of phenolic constituents by a hydrophobic styrene–divinylbenzene copolymerisate. After elution with methanol, the polyphenolics were concentrated in ...

online | memorias.ioc.fiocruz.br Early detection of drug resistance in Mycobacterium tuberculosis isolates allows for appropriate and timely treatment (Martin et al. 2008). There are many welldefined phenotypic methods for testing the drug susceptibility of M. tuberculosis. The proportion method, performed on Löwenstein-Jensen and 7H10 or 7H11 agar media, is recommended as a reference method. H...

Enzymes are the catalysts of all reactions in living systems. These reactions are catalysed in the active sites of globular proteins. The proteins are composed by amino acids with a variety of side chains ranging from non-polar aliphatic and aromatic to acidic, basic and neutral polar. This fact allows to a globular 3D protein to create in the active site all ranges of microenvironments for cat...
