Mean (n = 3) metabolic uptake and production rates of non-producer and producer cultures during exponential phase.

Rates are shown in µmol (gDW h)−1. Negative rates represent consumption and positive rates production of the corresponding metabolite.
1Differentially expressed transporters in producer and non-producer cultures according to Significance Analysis of Microarrays (SAM) using a false discovery rate of 5.17%. All amino acid transporters were upregulated in producer cultures. OUR = oxygen uptake rate, SE = standard error, Y = yield,
*indicates rates which were statistically significantly different (p<0.05, ANOVA) in producer and non-producer cultures.
