|Abstract:||Ustilago maydis is known to produce glycolipid-type biosurfactants. Here, we show that U. maydis is able to efficiently convert biodiesel-derived crude glycerol to glycolipids. We have optimized the medium composition and environmental factors for bioconversion of crude glycerol to glycolipids. The synthetic medium (MinCG) contains 50gL-1 crude glycerol and 20.3mgL-1 ammonium citrate as the carbon and nitrogen sources, respectively. The supplementation of trace amount of amino acids, Group-B vitamins and precursors of glycolipids, mannose and erythritol, also improved the final yield. At pH 4.0 and 30°C, 32.1gL-1 total glycolipids was produced in a 8.2-day fed-batch bioprocess. Methanol at 2% or above severely inhibited cell growth and production of glycolipids. Our results suggest that U. maydis is an excellent host for the bioconversion of crude glycerol to value-added products. © 2010 Elsevier Ltd.|
