Co-Utilization of Motor Oil Waste and Sunflower Oil Cake on the Production of New Sophorolipids by Candida bombicola NRRL Y-17069.

摘要

ABSTRACT Production of Candida bombicola sophorolipid (SL) was studied using a mixture of motor oil waste and sunflower oil cake as a substrate. In this work, submerged and solid state fermentation (SSF) techniques were used. The highest yield was achieved with SSF giving two fractions methanol fraction (F I) of 4.75 g% and ethyl acetate fraction (F II) of 41.77g%. To optimize the production, time course was studied. The minimum surface tension and critical micelle concentrations (CMC) were obt.
