I was wondering if someone could help me out with the results of an e. coli transformation i peformed...
The water control (water treated culture) on a LB-Amp (ampicillin) plate has no bacterial colonies (as expected), but there is the presence of 2 non-beta lactamase producing mold colonies on the plate. how is this possible?
I understand that lactamase would cause a breakdown of the ampicillin...but being non-beta lactamase, how would this be possible?
thanks so much!!
