Abstract

The variety of compounds present in chemically defined media as well as media supplements makes it difficult to use a mechanistic approach to study the effect of supplement composition on culture functionality. Typical supplements, such as soy protein hydrolysates contain peptides, amino acids, carbohydrates, isoflavones, and saponins. To study the relative contribution of these compound classes, a set of hydrolysates were produced, containing 58-83% proteinaceous material and 5-21% carbohydrates. While the content of the different compounds classes varied, the composition (e.g., peptide profiles, carbohydrate composition) did not vary in hydrolysates. The hydrolysates were supplemented to a chemically defined medium in cell culture, based on equal weight and on equal protein levels. The latter showed that an increase in the carbohydrate concentration significantly (P value¿
