Project summary:

Zymomonas mobilis is a natural ethanologen and uses Entner – Doudoroff (ED) pathway with 50% less ATP compared to glycolysis pathway, broad Ph range high alcohol tolerance and is defined has GRAS (generally regarded as safe) status. Therefore, Z.mobilis is a good alternative for the production of top building block chemicals like succinate, lactate, glycerate, glutamate from substrates including glucose, fructose, xylose. They are precursors for many secondary metabolites used in food, feed, pharmaceuticals and many other branches. Stoichiometric metabolic modelling in recent years has proven to be a powerful approach for a mechanistic understanding of complicated systems and processes and can be used to increase productivity and yield of chemicals.

ZYMMODEL will focus on model based strain design development suggesting knockouts and heterologous gene expressions to estimate the potential of industrial applicability of Z.mobilis in production of building block chemicals. Genome scale stoichiometric models of metabolism will be updated and optimized using flux balance analysis and structural analysis approaches. Published Omics data will be used for further constraining of the model where possible. ZYMMODEL will apply synergistically scientific fields of math, biology and information technology and disseminate this innovative approach for industrial biotechnology society more generally.
