Humidity for E.coli & how long can it survive?

Post by ek29 »

What is the optimal/recommended humidity for E.coli growth and how long can it survive in a petri dish with nutrient agar.

Hello,

The optimal humidity for E.coli growth is high, around 70%-90%. However, this can vary depending on the goal of your experiment. Under standard laboratory conditions, the bacteria can survive on a nutrient agar petri dish for several weeks. The duration may also vary based on the specific strain and environmental factors such as temperature, humidity, and other contents or stressors in the petri dish.

I hope that helps!
