Agriculture and food industries generate various waste streams that, in addition to being an economic loss, also contribute to the emission of greenhouse gases and other pollutants. Apart from solving these issues, microbial conversion of food waste to value-added products like biosurfactants will further reduce the carbon footprint and price of these products, as it replaces first-generation substrates that are the main contributors to these factors. In order to achieve this goal, strain and process engineering has been applied to enable the use of different waste streams as feedstock for biosurfactant production by the yeast Starmerella bombicola. Within this research, in the framework of the European BBI-JU funded WASTE2FUNC project and the FWO SB scholarship of ir. T. Van de Craen, the focus lays on various new-to-nature biosurfactants produced by modified S. bombicola strains. These novel biosurfactants are similar to sophorolipids but contain other functionalities that help to further broaden the applicability of the S. bombicola product portfolio. Physical and enzymatic pretreatment methods for the waste streams as well as genetic engineering towards achieving higher productivities of these new-to-nature biosurfactants will be of interest. In parallel, further engineering of S. bombicola for the in situ production of hydrolases in a consolidated bioprocess aims to simplify pretreatment and reduce production costs, as no enzymes need to be added in a separate process step. |
