Assay method for antimicrobial activity of antimicrobial agent

An assay method for antimicrobial activity of an antimicrobial agent, comprising:

• providing the antimicrobial agent to a culture medium in which strains are provided;
• shaking the culture medium based on a first time interval, and sampling the culture medium based on a second time interval;
• after the sampling of the culture medium, controlling movement of the culture medium such that the antimicrobial agent is to separate from a bacterial solution;
• and
• after the separation of the antimicrobial agent from the bacterial solution, culturing the bacterial solution, and then determining information regarding the antimicrobial agent.

An assay method for antimicrobial activity of an antimicrobial agent, comprising:

• providing the antimicrobial agent at a culture medium in which strains are grown;
• sampling, based on time, the culture medium having the provided antimicrobial agent;
• after the sampling of the culture medium, separating the antimicrobial agent from a bacteria at the culture medium;
• and
• after the separating of the antimicrobial agent from the bacteria, culturing the bacterial, and then determining information regarding the antimicrobial activity of the antimicrobial agent.
