Medium: R2A Incubation: 36º± 0.5º C for 5 ? 7 days. Reasoner DJ. Water Supply and Water Resources Division. Three different methods for performing the heterotrophic plate count, using three different types of media, will be described. OR; Heterotrophic Plate Count (cfu/mL) at 35°C/48 hours: "spreader" Membrane filtration, spread plating, and pour plating are conventional methods used to determine the heterotrophic plate counts of water samples. The heterotrophic plate count (HPC), formerly known as the standard plate count, is a procedure for estimating the number of live heterotrophic bacteria in water and.

STANDARD OPERATING PROCEDURE Procedure For Conducting Heterotrophic Plate Counts. The pour plate count agar was prepared as described in Standard Methods.
Why is the heterotrophic plate count method performed on food productsA heterotroph is any organism that cannot make its own food and is. By the very nature of the procedure, the dead cells are unable to be.
