Streak plating vs spread plating
WebA streak plate is when you take bacteria on the end of an object, like an inoculation loop or a swab, and "streak" the agar plate with it. A spread plate is when the bacteria are suspended in a liquid, like culture broth, the liquid is added on top of the agar plate, and either beads or a "hockey stick" are used to spread the liquid, and ...

WebThe plate count method or spread plate relies on bacteria growing a colony on a nutrient medium. The colony becomes visible to the naked eye and the number of colonies on a plate can be counted. To be effective, the dilution of the original sample must be arranged so that on average between 30 and 300 colonies of the target bacterium are grown. Web11 Apr 2024 · The streak plate method is a rapid qualitative isolation method. The techniques commonly used for isolation of discrete colonies initially require that the number of organisms in the inoculums be reduced.
