Candida bombicola, sophorolipids

Sophorolipids (SLs) are extracellular glycolipids that are normally synthesized from glucose and a fatty acid source (either FFA or triacylglycerol) by a number of yeasts (primarily Candida bombicola). They are composed of a disaccharide (sophorose 2-O-P-D-glucopyranosyl-p-D glucopyranose) attached to a hydroxy fatty acyl moiety at the co-1 or co carbon (Fig. 7.5). Typi-...

In the ciurent stndy the inflnence of aeration rate, inoculum size and fermentation medium volume on the sophorolipids production from the yeast Candida bombicola have been studied. Using the data obtained from a two-level Placket-Biuman ejqjerimental design, linear and cubic models were obtained to understand the interaction amongst the ingredients. The cubic model was used to find the optimal aeration rate, inoculum size and the fermentation medium volume. The maximum production of SLs is predicted to be obtained when the medium volume is 10 mL (in 125 mL Erlemneyer flask), is inoculated with 5% of the inoculum and incubated at 350 rpm... 

Sophorolipids are mainly produced by the yeasts such as Candida bombicola and Candida apicola species." They have CMC of around 40-100 mg/L.They can be used to stabilize oil in water emulsions as their hydrophilic/lipophilic balance is between 10-13. ...
