Clone rankings obtained in YNB (A) after 80 h and Syn6 medium (B) after 72 h during MBR cultivations. In blue, lipolytic activity and, in yellow, optical density at 600 nm. Numbers in circles indicate selected clones for further cultivation experiments. A: Mean values of three replicate wells. B: Values obtained from single well cultivations. Ranking criteria was volumetric lipolytic activity.
