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 ... Microbiologists use a technique called the ‘standard plate count’ to estimate the population density of bacteria in a broth by plating a small and dilute portion of the sample and counting the number of bacteria colonies. We use serial dilutions to create decreasing concentrations of the original sample that are then plated so that a plate will be created with a low enough number of ... Total plate count can be made using plate count agar. This microbiological growth medium is not a selective medium, Arasains Indonesia provides biolife Standard plate count agar. Typically this agar consists of peptone, yeast extract glucose and agar. Two methods of growing is usually practiced- the pour plate or the spread plate. FIG. 4.

Association of Food and Drug Officials, York, PA. Andrews, W.H ... Plate Count Agar or Standard Methods Agar (PCA or SMA) _____ 1. Prepare and sterilize agar for sample series and all controls _____ 2. OR use previously prepared/stored agar; melt agar quickly in . boiling water or flowing steam; not under pressure _____ 3. Do not melt agar more than once _____ 4. Promptly place in a circulating water bath to temper, hold . melted agar at 45 ±1°C _____ 5 ... The poured plate count method is preferred to the surface inoculation method, since it gives higher results. Plate Count Agar is also suitable for enumerating bacterial count of sterile rooms. Quality Control Appearance Cream to yellow homogeneous free flowing powder Gelling Firm, comparable with 1.5% Agar gel Colour and Clarity of prepared medium Light yellow coloured clear to slightly ... Total Plate Count (TPC): To enumerate bacteria present in a sample by serial dilution agar plating method or total plate count (TPC) method. Purpose: The extent of bacterial activity in a given sample in a definite set of conditions mainly depends on the total number of bacteria present in it irrespective of their species. Direct Count Spectrophotometer Viable Plate Count Which one requires the least time (for example, the boss wants the answer before lunch)? NOT TOO BAD - counting can be time-consuming, but the answer could be available before lunch. FASTEST - but only if you already have the calibration curve!!! SLOWEST - we have to wait an entire day Consider your reason for testing – one educational method is to use a contact slide and leave in place at the facility; or you may wish to demonstrate hygiene problems and want a quantitative result (sample must be sent to the laboratory for a report to be issued). 4. Determine the type of environmental sampling you require: swab samples, sponge samples, contact slides. Check availability of ...
