چکیده

According to the International Dairy Federation, the quality of raw milks shall be evaluated by the determination of "total" bacterial counts, or standard plate count (SPC); after serial dilution of the milk samples, the SPC is determined on Plate Count Agar (PCA) by the "pour plate" method; the viable bacteria are enumerated after aerobic incubation for 2 or 3 days, at 32 °C or 30°C respectively.

Enumeration and characterization of standard plate count bacteria in chlorinated and raw water supplies.

Nearly 700 standard plate count (SPC) bacteria were isolated from drinking water and untreated surface water and identified according to a scheme developed to permit the rapid, simple classification of microorganisms to genus, species, or group. Actinomycetes and Aeromonas species were the two most common groups of SPC bacteria in chlorinated distribution water. Aeromonas spp. and Enterobacter ...
