Streak Plate Method: Principle, Procedure, Uses - Microbe Online An agar plate is taken and appropriately labeled. Using a sterile (flamed) loop, a loopful sample is carefully spread on the edge of the agar. (Care should be given not to gauge the agar) The loop is famed, and after cooling, 7-8 straight lines are streaked from area 1 to the opposite side of the plate. Pour Plate Method: Procedure, Uses, (Dis) Advantages For accurate counts, the optimum count should be within 30-300 colonies/plate. To ensure a countable plate, plate a series of dilutions. The pour plate method of counting bacteria is more precise than the streak plate method.On average, it will give a lower count as heat-sensitive microorganisms may die when they come in contact with a hot molten agar medium.

Aseptic Laboratory Techniques: Plating Methods - PMC Label around the edge of the bottom (not the lid) of an agar plate with at least your name, the date, the type of growth medium, and the type of organism to be plated on the medium. The plates must be completely dry without condensation on the lid and pre-warmed to room temperature prior to streak-plating. Streak Plate Method - Amrita Vishwa Vidyapeetham Write close to the edge of the bottom of the plate to preserve area to observe the plate after it has incubated. Labels usually include the organism name, type of agar, date, and the plater's name or initials. Using sterile cotton swabs, remove any visible water on the agar in the plate or around the inner rim of the petri plate. PDF Lab 9 Serial Dilution, Pour Plates, and Enumeration of Bacteria Gently swirl the Nutrient Agar and diluted bacteria samples together, and let the Petri plate solidify. This is called the pour plate technique. Incubate for 24 to 48 hours at 37°C. Part II: Enumerating Bacterial Densities (the following week) After incubation, count the number of bacterial colonies growing in Petri plates labeled #2, #3, and ... Streak Plate Method - Explained - Laboratoryinfo.com The streak plate method requires the number of organisms in the inoculums be reduced. The procedure includes a dilution technique which requires spreading a loopful of culture over the agar plate surface. This is to make sure that the individual cells fall apart on the agar medium surface so as separation of the different species takes place.
