Eighteen several hours just isn't Significantly time! One method to make sure the micro organism can meet this rigid deadline is always to stack agar plates only 4 plates superior. An incubator filled with check here tall stacks of agar plates will take extended to warm up than an incubator with compact stacks, plus the plates in the middle of the stacks will even just take lengthier to heat up. The agar plates will need to achieve 30˚C to 35˚C swiftly to give the micro organism enough time to grow.
