Biological fermentation surfactant, cosmetic and preparation method thereof

The invention discloses a biological fermentation surfactant, a cosmetic and a preparation method thereof, and relates to the technical field of biological fermentation. The preparation method of the biological fermentation surfactant comprises the following steps: inoculating candida on a culture medium for fermentation; the culture medium comprises a water-soluble carbon source, a fat-soluble carbon source and a nitrogen source. The biosurfactant is prepared by using a candida strain through a fermentation process, and a fermentation product obtained by fermentation has foam increasing and foam stabilizing performance of a traditional petrochemical surfactant by optimizing the composition of a culture medium and accurately regulating and controlling the content of a soluble carbon source, a fat-soluble carbon source and a nitrogen source in the culture medium, so that the irritation of the product can be reduced. 本发明公开了一种生物发酵表面活性剂、化妆品及其制备方法，涉及生物发酵技术领域。生物发酵表面活性剂的制备方法包括：将假丝酵母菌接种于培养基上进行发酵；其中，培养基包括水溶性碳源、脂溶性碳源和氮
