Corynebacterium glutamicum as platform for the production of hydroxybenzoic acids.

By abolishing its natural catabolic network for aromatic compounds, C. glutamicum was turned into a versatile microbial platform for aromatics production, which could be exemplarily demonstrated by rapidly engineering this platform organism towards producing four biotechnologically interesting hydroxybenzoates. Production of these compounds was optimized following different metabolic engineering strategies leading to increased precursor availability. The constructed C. glutamicum strains are promising hosts for the production of hydroxybenzoates and other aromatic compounds at larger scales.
