Abstract
The subject invention provides improved methods for producing mannosylerythritol lipids (MEL) using yeasts not previously known to produce MEL. In particular, Meyerozyma guilliermondii (Pichia guilliermondii) is cultivated in a specially-tailored nutrient medium and under cultivation conditions such that the yeast unnaturally produces MEL and/or MEL-like molecules in greater amounts and at increased rates than when using standard MEL production with, for example, Pseudozyma aphidis. Yeast culture compositions are also provided, comprising yeast cells, growth medium, and high concentrations of MEL.
