SEED FUND 3.0 - Project OpTooGlu

Optogenetic Toolbox for Two-color Light-controlled Gene Expression in the Acetic Acid Bacterium Gluconobacter oxydans

Project: OpTooGlu


OpTooGlu aims to develop and establish new optogenetic tools for temporal gene expression in bacteria and the first ones for the acetic acid bacterium and versatile industrial workhorse Gluconobacter oxydans because of its huge biotransformation potential. The ultimate goal is to establish the simultaneous use of UV-A- and green light-sensitive caged effector molecules for two-color bioprocess engineering strategies to control cellular functions in bacteria. For Gluconobacter, the new optogenetic tools developed herein will be used for the first time as a proof-of-concept in bioprocess engineering by light-mediated temporal control of gene expression to optimize expression of membrane-bound dehydrogenases for improved high-level production of the high-value compound L-arabinonic acid from renewable L-arabinose present in related biorefining biomass streams.
