Overview
Soy Protein Powder B50 is a fine light yellow to beige powder containing proteins, amino acids, B-complex vitamins and other essential nutrients. Its slow nitrogen release profile makes it suitable for prolonged fermentation processes and high-cell-density cultivation.
Soy protein powder or soy peptone
Soy protein powders and isolates are soy protein that has not been extensively hydrolysed: large molecules at low cost, usable only once the organism secretes proteases, which suits protease-producing strains such as Bacillus and large, long industrial fermentations, and they can replace soy milk to avoid batch variation and spoilage. Soy peptone is already hydrolysed to peptides, taken up quickly and clear in solution, for laboratory media and fermentations that need a fast start.
