The present invention generally relates to a system and process for producing a biosurfactant, and more particularly to a system and process for producing a biosurfactant from at least one strain of Bacillus subtilis, and formulations which comprise the biosurfactant.

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.
