Figure 5. Bacterial community composition at the class level of the in the flow-through and closed rolling tank system.

The community in the flow-through rolling tank was sampled at the outlet of the tank and is presented together with the community in-situ in the lake as well as at the inlet to the tank following the pumping of water. In addition to total community analysis (>0.2 μm), on the fourth day, the free-living (FL; >0.2 μm & <5 μm) and particle-associated (PA; >5 μm) communities were analyzed separately.
