Fig. 11.. Live/dead CLSM 3-D images of biofilms and biofilm thickness from (a) X52 steel exposed to LW1 for 14 days, (b) X52 steel exposed to LW2 for 14 days, (c) X52 steel exposed to LW1 for 30 days, and (d) X52 steel exposed in LW2 for 30 days. LW1 represents incubation in lake water alone, and LW2 represent incubation in lake water with added 2216E culture media.
