Table 1 Kinetics and stoichiometry of cis, cis-muconic acid (MA) production of Corynebacterium glutamicum MA-1 from benzoic acid, catechol or phenol, and of Corynebacterium glutamicum MA-2 from catechol

From: Metabolic engineering of Corynebacterium glutamicum for the production of cis, cis-muconic acid from lignin

  1. The data comprise the specific glucose uptake rate (qGlc), the specific MA production rate (qMA), the biomass yield (YX/Glc), and the MA yield (YMA/Aro) and represent mean values and standard deviations from three biological replicates. The culture of the MA-1* strain additionally contained benzoate as inducer
