How would you determine the minimum bactericidal concentration of a given microbial agent?

I assume you are referring to the MBC of an anti-microbial agent.
Generally it is determined by subculturing on agar plates, and much of the time, by counting colonies.
MBC is the minimum concentration to kill ≥99.9% of a given bacterium. Do not confuse with MIC (minimum inhibitory concentration) which inhibits growth.
The detailed laboratory procedures may be found, for example, in scholastic journals such as:
