For protecting our earth and health, a trend was happening that more and more products and materials are produced by bio-fermentation process instead of chemical synthesis. For growing microorganisms and cells during fermentation process to get desired products, microbial nutrients such as yeast extract and plant-based peptone of non-animal origin are key factors. Angel Yeast’s microbial nutrients solution can help bio-fermentation industry achieve “clean, safe, efficient and stable”production.
