WebbDescription Plate Count Agar is equivalent to the medium recommended by the APHA 1, PHLS 2 and ISO 3,4 for the plate count of micro-organisms in food. The APHA method consists of the preparation of pour plates using diluted samples, and counting colonies after incubation. Incubation is for 48 hours at 32°C or at 35°C for the Standard Plate Count. WebbThe appropriate number of colonies to count on a plate is a function of colony size, plate size, and size of differential properties produced on the medium. Typically, 25 to 250 colonies per plate yield reliable results. Use this as a guide unless an alternate range is indicated for specific methods.
