Malatproduktion aus Rohglycerin mit Ustilago

The use of biodiesel derived crude glycerol for the production of value added chemicals has been discussed frequently. Current glycerol-based microbial production process often suffers from low rates, titers, and yields, hindering their industrial application. Here we report on the identification and optimization of Ustilago trichophora as promising novel production organism for malic acid from glycerol. All optimization steps presented avoid metabolic engineering resulting in a non-GMO organism.
