1 Microbiological Methods I-A- MESOPHILIC AEROBIC BACTERIA (STANDARD PLATE COUNT OR TOTAL PLATE COUNT) PRINCIPLE Viable bacteria are quantitated by the fractional gram pour plate technique. SCOPE The method is applicable to starches, syrups and sugars and most coproducts of the corn wet milling industry. MEDIA AND REAGENTS 1. Plate Count Agar (PCA). Prepare according to the manufacturer's directions. 2. Butterfield's Phosphate Diluent Stock Solution: Dissolve 34 g of potassium dihydrogen phosphate (KH2PO4) in 500 mL of purified ...
® SimPlate Total Plate Count Introduction ® SimPlate for Total Plate Count (TPC) method is used for the detection and quantification of the total aerobic ® microorganisms in food. The medium/sample mixture is dispensed into a SimPlate device and incubated for 24-28 h. The total aerobic plate count is determined by counting the fluorescent wells and referring to the ® ® SimPlate Conversion Table. The SimPlate device is packaged separately. Single Test Medium Multiple Test Medium Kit Components Kit Components ...

Microbiologics Dilutions Guide This document outlines how to perform dilutions when using Microbiologics products. Dilution is the process of making a solution weaker or less concentrated. In microbiology, serial dilutions (log dilutions) are used to decrease a bacterial concentration to a required concentration for a specific test method, or to a concentration which is easier to count when plated to an agar plate. This document was created to provide a better understanding of dilutions and should be used as a ...
