Table 3.

Substrate utilization and metabolite production of co-cultures. Co-cultures were grown in YCFA supplied with glucose and glycerol (both 50 mM) at 37 °C for 24 h. Substrate utilization and metabolite production were quantified with HPLC-RI. n = number of biological replicates. Values are presented as mean ± standard deviation
