Abstract
Abstract Renewable resources, such as rapeseed oil or oleic acid, combined with glucose were used both in a feed-batch and two-stage continuous process for the production of sophorolipids with the yeast Candida bombicola ATCC 22214. High yields >300 g l −1 and increased productivities of 57 g l −1 d −1 (feed-batch) and 76 g l −1 d −1 (continuous mode), respectively, were obtained by using optimized cultivation conditions. The key-factors for enhanced sophorolipid production are presented. The acidic sophorolipid was used for further modification after alkaline hydrolysis and purification. A novel glucoselipid was synthesized by using the enzyme naringinase (EC 3.2.1.40). A (ω-1)-hydroxyfatty acid, commercially not yet available and difficult to prepare by organic synthesis, was released by acidic hydrolysis, purified and is proposed as a precursor for plastics and flavours.
