Abstract
Disclosed herein are compositions comprising a sophorolipid surfactant and a bio-synergist and the methods of using the same.
Claims19
A composition comprising a sophorolipid surfactant and a surfactant bio-synergist (SBS),
- wherein the sophorolipid surfactant is produced by partially hydrolyzing a fermentation product of Candida bombicola grown with glucose;
- and
- wherein the SBS is a metabolite broth produced by a method comprising:
- growing yeast under aerobic fermentation conditions to obtain a fermentation mixture comprising fermented yeast cells, and proteins and peptides secreted therefrom;
- subjecting the fermentation mixture to stress in order to stimulate the yeast cells to express heat shock proteins, to obtain a stressed fermentation mixture;
- and
- separating the stressed fermentation mixture to form a solid/precipitate and a supernatant, wherein the resultant supernatant is the SBS.

A method of lowering the critical micelle concentration (CMC) value of a sophorolipid surfactant, comprising adding to the sophorolipid surfactant an amount of a surfactant bio-synergist (SBS), wherein the SBS is a metabolite broth produced by a method comprising:
- growing yeast under aerobic fermentation conditions to obtain a fermentation mixture comprising fermented yeast cells, and proteins and peptides secreted therefrom;
- subjecting the fermentation mixture to stress in order to stimulate the yeast cells to express heat shock proteins, to obtain a stressed fermentation mixture;
- and
- separating the stressed fermentation mixture to form a solid/precipitate and a supernatant, wherein the resultant supernatant is the SBS.
