Notes.

The original biofilm was cultivated in triplicates in these conditions at pH 8.0. The carriers were transferred five times in fresh medium (eight times for the 200-200N biofilm cultures). In gray are changed parameters from the Ref300N-23C biofilm cultures. IO: Instant Ocean medium.

a

Reference biofilm cultures.

b

Cultures were performed under oxic conditions.

c

The Ref300N-23C biofilm cultures were further transferred three times in ASW composed of 5% NaCl.

d

Based on the amount of Na+ and Cl- in Table S1. The exact amount of NaCl added in the IO medium is not known. For comparison, the amount of Na+ and Cl- in the ASW medium is 3.2%.
