Description

Amino acid play an important role both in animal metabolism and in industrial processes. Since they are rarely found in nature in free form, they must be obtained form hydrolisis of protein-containing materials, or by fermentation. These production methods often results in aqueouse mixtures containing various solutes included several types of amino acids. As a consequence, the cost of the separation processses and concentration of biomelecules from the media can be as high as 90 per cent of their total manufacturing cost.
