Questions & Step-by-Step Solutions
What is the minimum inhibitory concentration (MIC) of a drug that inhibits 90% of a bacterial population at a concentration of 2 mg/L?
Correct Answer: 2 mg/L
Step 1: Understand what MIC means. MIC stands for Minimum Inhibitory Concentration, which is the lowest amount of a drug needed to stop bacteria from growing.
Step 2: Look at the information given. The question states that a drug inhibits 90% of a bacterial population at a concentration of 2 mg/L.
Step 3: Recognize that the MIC is the lowest concentration that stops visible growth. Since 2 mg/L inhibits 90% of the bacteria, it is also the concentration that stops visible growth.
Step 4: Conclude that the MIC is the same as the concentration given, which is 2 mg/L.
