International Conference: Research and Industrial Applications


Andreas Aurich form UFZ will hold an oral presentation at an International Scientific Conference about biotechnologies in Wroclaw, Poland, from the 20th to 21st of June.

His oral presentation will be :  « Production of organic acids by the yeast Yarrowia lipolytica »

Read the full abstract below:

Functionalized carboxylic acids are highly versatile chemical species with a wide range of applications Therefore they are of special interest as biotechnologically available targets. The yeast Yarrowia lipolytica secretes high amounts (from 100 up to 200 g/L) of various organic acids, like citric (CA), isocitric (ICA), ketoglutaric (KGA) and pyruvic (PA) acids, under different conditions of growth limitation (by nitrogen or thiamine) from a carbon source excess. The aim of these studies was the application of genetically engineered Y. lipolytica strains in combination with the development of bioprocess fundamentals for the efficient production of TCA cycle acids regarding the variable use of renewable substrates and industrial by-products (including plant oils, sucrose, biodiesel - FAME, and raw glycerol)
