Streak Plate Method - Principle, Types, Methods, Uses | PDF ... It was loeffler and gaffky who first developed this method in koch’s laboratory. the procedure involves diluting bacteria by streaking the bacteria over the surface of the agar in the petri dish. that way, an isolated colony can be obtained and grow into a number of cells. Learn the streak plate method in microbiology: its principle, various streaking techniques, procedures, and applications for isolating pure bacterial cultures.

Streak Plate Method- Principle, Types, Methods, Uses, 46% OFF For organisms that grow well on agar plates, a streak plate is the method of choice for obtaining pure culture. the streak plate technique is used to isolate the organisms (mostly bacteria) from a mixed population into a pure culture. The streak plate method is a microbiological culture technique where a sample is spread in a petri dish in the form of a long, thin line over the surface of solid media. Sterilize the inoculating loop by flaming and allow it to cool. pick a small portion of the isolated colony. (if the sample is in the suspension, then take a loopful of the sample) the inoculating procedure is different according to the method of streaking, let us deal with each type. Learn the streak plate method for isolating pure bacterial cultures. discover its principles, techniques, significance, and limitations in microbiology.

Learn the streak plate method for isolating pure bacterial cultures. discover its principles, techniques, significance, and limitations in microbiology. The most common way of separating bacterial cells on the agar surface to obtain isolated colonies is the streak plate method we used in lab 2 to inoculate a petri plate. it provides a simple and rapid method of diluting the sample by mechanical means. Using sterile cotton swabs, remove any visible water on the agar in the plate or around the inner rim of the petri plate. observe the plate and mentally divide it into three sectors. the plate will then be turned clockwise (if you are right handed) with the agar side up. Streak plates are used to isolate escherichia coli from water by streaking the sample across a nutrient agar plate, flaming the loop between quadrants. a clinician may streak a throat swab onto blood agar to isolate streptococcus pyogenes and observe hemolysis patterns. For the streak plate method, one loopful of bacterial culture is diluted by streaking it onto the surface of an agar plate, making sure the cells are spread out.
