TABLE 1.

MICs and MBCs of heavy metals^a

Cells	Medium	MIC (mM) of:			MBC (mM) of:
		Cu	Zn	Pb	Cu	Zn	Pb
Planktonic		2	8	0.125
Planktonic	MSVP				0.125	>64	0.3
	MOPSO				0.01	2	0.25
Biofilm	MSVP				>6	>64	0.8
	MOPSO				6	>64	>0.4

^aMICs were determined after 56 h, and MBCs were determined after 5 h by using the rotating-disk reactor.
