Biofilms on R.O. water dispenser's membrane filters

[chimezie]

Suggest fastest techniques for identifying biofilm community in membrane filters of Reverse osmosis-water dispensing machines.

[canalon]

16S PCR followed by either cloning and sequencing or by next gen sequencing without cloning. Might be expansive though.

[michimichi]

you mean to identify the organisms specifically?
if the HPC is always too high there is a possibility that there is a biofilm community.
