could you please help with this little question as I have not been using McConkey before:
My objective is to artificially contaminate a sample with a reference E.coli, then apply a treatment in sepcific conditions and later enumerate. (growth changes)
What shall I use? McConkey agar (regular) or McConkey with sorbitol?
there are papers who used the McConjey sorbitol , others used the Rapid'2 E.coli agar from Biorad. I have McConkey available (without sorbitol).
the advice and comments are appreciated !
