Thank you for these lectures !!!

Great explanation.thanks alot

I have a doubt, so as u said, UV light can lead to DNA mutations and the cell's death. Are there any instances where the mutations formed inside the bacterial cell did not kill them but made them more lethal and resistant? .... I hope someone can help me with this question.

Dr. Julie, what was your initial concentration of bacteria plated? I tried this experiment with a coliform I isolated from pool water samples and treated it with UVA and UVC light, neither made a visible dent in the population. I treated with UVA for 30 sec, 1 min, 2 min, but they grew as confluent as the control. I repeated with a UVC light and the issue persists. I am going to serially dilute to see if concentration is the culprit, but your experiment doesn’t seem to be affected by this factor. Any thoughts?
