Abstract: The subject invention provides methods and compositions for replacing chemical surfactants for use in a wide variety of industrial applications. More specifically, the subject invention provides for the production of multi-functional biological surface-active compositions having one or more precise functional characteristics based on the desired use.

Abstract: The subject invention provides systems, apparatuses and methods for cultivating microorganisms and for producing microbial metabolites on a large scale. Specifically, in certain embodiments, a system comprising three separate, but connected, vessels is provided, wherein a first vessel serves as a feed tank for supplying nutrient medium to a second vessel, said second vessel serving as a submerged fermentation reactor; and wherein a third vessel serves as a collection container into which foam containing microbial growth by-products is transferred from the second vessel.

Abstract: The subject invention provides improved methods for producing fatty acid esters using yeast not previously known to produce fatty acid esters. In particular, Meyerozyma spp. can be cultivated under specially-tailored conditions such that the yeast produces a variety of fatty acid esters. A yeast culture and fermentation compositions are also provided, comprising yeast cells, liquid growth medium, and a high concentration of growth by-products, such as fatty acid esters.
