Interpretation of decontamination results
Plate	Expected carbenicillin titer	If not?
Pre-infection control	0	Cells were pre-infected; nothing can be concluded from the experiment.
Contamination control	lawn	Insufficient contamination to be able to assess efficacy of subsequent decontamination; consider submerging manifold in phage solution rather than aspirating it.
Decontamination test	0	Decontamination not complete; increase soak time, bleach concentration or try SDS and EtOH washes instead.
