TLDR
Investigation of the ability of Candida bombicola to fermentatively transform the restaurant oil waste into glycolipids called sophorolipids found that the highest yield was attributed to the fatty acid composition of restaurantOil waste.Abstract:
Approximately 100 billion liters of oil is generated per week as waste from restaurants around the country. Because of health, environmental, and economic factors, current methods of disposal are ineffective for disposal of the restaurant oil wastes. In this study we have investigated the ability of Candida bombicola to fermentatively transform the restaurant oil waste into glycolipids called sophorolipids. Batch and fed-batch studies were carried out using oil waste as the lipid feedstock in Erlenmeyer flasks and in a fermentor. Batch fermentation in a fermentor gave the highest yield of sophorolipids of 34 g L -1 . Fermentation using oleic acid as control feedstock were also carried out. Batch fermentation in the fermentor using this pure fatty acid gave a highest yield of 42 g L -1 . The difference in the sophorolipid yield was attributed to the fatty acid composition of restaurant oil waste.read more

Production, Characterization, and Properties of Sophorolipids from the Yeast Candida bombicola using a Low-cost Fermentative Medium
TL;DR: The yeast Candida bombicola produces biosurfactant with properties akin to those of sophorolipid (SL) group of compounds when grown on a cheap fermentative medium containing sugarcane molasses, yeast extract, urea, and soybean oil.

TL;DR: The sophorolipid diacetate ethyl ester derivative is the most potent spermicidal and virucidal agent of the series of SLs studied and its structure-activity relationship has been established for creating new analogs with less cytotoxicity and higher activity.

TL;DR: The Torulopsismagnoliae oil formed during fermentation by a strain of Torusismagniae consisted mainly of partly acetylated 2-O-β-D-glucopyranosyl-Dglucophyranose units attached β-glycosidically to 17-L-hydroxy oct... as discussed by the authors.

Sophorolipid biosynthesis by Candida bombicola from industrial fatty acid residues.
TL;DR: Saturated and monounsaturated C18 fatty acid gave the highest levels of sophorolipid production while fatty acids with more than one site of unsaturation gave much lower yields, and nickel contaminated stearic fatty acid residue was transformed to value added sophorlipid product.
