a
Whole cells were treated with a 1 mM solution of La(NO3)3 · 6H2O for 15 min at 22°C.
b
Data are values from separate measurements of three whole-cell–metal interactions.
c
Amount of metal which precipitated chemically during the 15-min treatment period.
d
The values for PAO1 and dps89 are significantly different from each other, and the value for AK1401 is significantly different from all other values. The values for PAO1 and rd7513 are not significantly different from one another.
