In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. Supplies needed for streak plating: Petri dish of sterile TSY medium (or a specialized growing medium) Aseptic technique or sterile technique is used to avoid contamination of sterile media and equipment during cell culture. Coli (all BSL2) 3 TSA plates Streaking for Isolation Procedure There are several methods of streaking for isolation. 3. Streak plate facilitates isolation and purification of a specific bacterium while spread plate facilitates enumeration of bacteria in a sample. The procedure includes a dilution technique which requires spreading a loopful of culture over the agar plate surface. University of Guyana Faculty of Natural Sciences Department of Biology BIO2100:Laboratory and Field To effectively capture motion blur, slow down your shutter speed, and hold your camera still as your subject moves. Source: Ravi's Microbiology Source: Ravi's Microbiology Clearly labeling your plates to identify the microorganism only takes a few seconds and will help you avoid a big headache later. Enamel type streaking for modelling. Sterile technique should always be employed when working with live cell cultures and reagents/media that will be used for such cultures. Samples can then be taken from the resulting colonies and a microbiological culture can be grown on a new plate so that the organism can be identified, studied, or tested. Depending upon the number of agar sections streaked, the following are patterns of streaking. 3,60 . Question : What are the different types of streaking techniques in microbiology? Microbial aerosols created from the hitting of the inoculation tip to the sides of the agar plate. Spread Plate Method 4. They should then regress in size and lightness toward the crown. As you might guess, the purpose of streaking for isolation is to produce isolated colonies of an organism on an agar plate. Quadrant Streaking It is the most commonly used and the most preferred method where four equal-sized sections of the agar plate are streaked. Streak Plate Method and isolation techniques . Shake well before use. The methods are: 1. (2) Among the three techniques used, streak plate is the most efficient way to produce well-isolated colonies, or in other words, pure colonies.
