Complexation between proteins and polyelectrolytes through electrostatic interactions gives either soluble or non-soluble complexes, leading to phase separation. The formation and the stability of these complexes are ...

In this paper the issues and challenges presented 15 years ago for performing efficient separation processes for recombinant proteins are revised and discussed. Competitive advantage in production was seen as not only ...

The precipitation of endoglucanase from Aspergillus niger with synthetic and natural electrically charged polymers -poly vinyl sulfonate (PVS) and chitosan (CHS)- was characterized and applied to a simple method of ...

A one-step method as a strategy of alpha-amylase concentration and purification was developed in this work. This methodology requires the use of a very low concentration of biodegradable polyelectrolyte (Eudragit® E-PO) ...

The actual biotechnology industry demands fast and economic upstream and downstream processes to purify biomolecules. In this context, different purification techniques, that offer both high recovery and purity to the final ...
