2012). If one requires a specific sophorolipid isoform, chromatographic methods with silica or preparative reversed-phase columns are required (Lin 1996). Yet, this is only feasible at small scale. 4 Costs Obviously, production price depends on several factors: the type of substrates used and the hereto connected yields, product recovery strategy and required purity, scale, and so on. From these factors, scale has the main influence on the production price; large-scale production allows big investments in equipment and maintenance bringing down the cost per kg of the product.

6 REGULATION OF SOPHOROLIPID BIOSYNTHESIS Sophorolipids are mainly secreted during the stationary phase and their presence is not obligatory for cell viability. Hence, they can be considered as secondary metabolites. The molecules are Sophorolipids 25 produced at certain limiting conditions in excess of a carbon source and, therefore, it is suggested that they act as an external carbon sink. In other fungal organisms producing glycolipids, for example, MELS and cellobiose lipids, the expression of the clustered genes is controlled by a transcription factor that is activated in response to a changing environment.
