  1. Data are fitted with linear regression using datasets from ten ([Fe(CN)6]3−/4−) and four ([Co(bipy)3]3+/2+) biological replicates with a total of 79 and 36 samples, respectively (compare Additional file 1: Fig. S3). Carbon balance is calculated from the fitted rates considering carbon content of molecules and assuming equimolar CO2 production when making acetate from glucose. Gluconic acid is a product in the first 100 h and serves as a substrate thereafter, hence 2 yields and rates are given
