Streak Plate Method - Principle, Types, Methods, Uses | PDF ... Learn the streak plate method in microbiology: its principle, various streaking techniques, procedures, and applications for isolating pure bacterial cultures. Here we present the steps for several plating methods routinely used in the laboratory to isolate, propagate, or enumerate microorganisms such as bacteria and phage. all five methods incorporate aseptic technique, or procedures that maintain the sterility of experimental materials.

Principle Microbiology: Streak Plate Method

Principle Microbiology: Streak Plate Method In this method a sterile inoculating loop is first dipped into a diluted bacterial culture; then the culture containing loop is streaked on the surface of a solidified agar plate to make a series of parallel, non overlapping streaks. 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. The streak plate method is simple, reliable, convenient, and easy to perform. it yields well isolated colonies of genetically identical individuals, allowing for further testing and applications, making it suitable for clinical diagnosis. 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.

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. Two commonly used ones in our lab are the streak plate and the pour plate methods. these involve diluting bacterial cells in a sample down to an end point of a single genotype dividing and giving rise to a single pure colony. a colony is a collection of identical cells of the same bacterial strain, growing on or within a solid medium. “streaking for isolation” is a critical microbiology technique! see pictures in powerpoint for how to perform the. quadrant method for streaking for isolation. disinfect lab bench. do activity individually, but share one stock culture in each group. In a streak plate, an agar plate is divided into three sections. an inoculum from a pure culture is inoculated with a sterile swab in a zigzag pattern onto the first (and largest section) section of the agar plate. Learn the streak plate method for isolating pure bacterial cultures. discover its principles, techniques, significance, and limitations in microbiology.
