This hold off decreases the growth time in the cells around the plates in the course of the stack. If the plates are all checked for growth at the same time, the plate on the best and bottom of the stack should have developed greater than Those people in the midst of the stack. Colonies will look greater and the differential macroscopic more info features observed much more Obviously.
