How come bacteria can grow so massive in a petri dish but doesn’t in a normal enviroment?
In: Biology
Petri dishes have different mixtures of mediums that bacteria like.
Say your trying to grow one particular bacteria from a random mixture . You plate it on something they like with a specific technique and you incubate it at their preferred temperature. If it’s something that causes disease in humans then you incubate it at 37C and mimic the similar conditions that humans have.
If I want something that grows well in salty environments then I would use an agar that is salty. This will inhibit other bacteria that doesn’t like salt.
