Question:
What additional steps would be taken to determine whether the bacteria in the zone of inhibition are alive or dead, to see if the chemical was bacteriocidal or bacteriostatic?

Hi Melissa,

Some more info would help here. What are you trying to do? What's your experimental setup? You mention 'additional' steps -- what have you tried already? It sounds like you know the different between -cidal and -static, so is this just a microbiology-lab-technique question? What is your application (e.g. presentation to kids, lab report / class assignment, etc.)? Also, if applicable, who is your audience (age/level)?

Thanks,
Burr
