- •
MC-LR degradation by biofilm was inhibited by Mn2+ and Cu2+, but not affected by Zn2+.
- •
MC-LR can be degraded only after a lag phases of 2 days and 8 days for Zn2+ and Cu2+ cases.
- •
The abundance of MC-LR degradation bacteria over biofilm was reduced by Mn2+.
- •
The abundance of MC-LR degradation bacteria over biofilm was not affected by Zn2+.
- •
The abundance of MC-LR degradation bacteria over biofilm was enhanced by Cu2+.
