The techniques commonly used for isolation of discrete colonies initially require that the number of organisms in the inoculums be reduced. The technique is done by diluting a comparatively large concentration of bacteria to a smaller concentration. Using a sterile (flamed) loop, a loopful sample is carefully spread on the edge of the agar. Loeffler and Gaffkey introduced the streaking method. 3. Streaking method. Streak Plate Method Definition It refers to the pure culture technique that involves inoculating the separated colony from the mixed culture (either broth culture or directly from the culture plate/slant) over the solid agar surface by moving the sterilized inoculating loop back and forth. May kill microorganisms if you don't allow to cool sufficiently; agar may . This Semi-quantitative Streaking Label the plate and incubate it inverted. Pour plate : Disadvantage. Streaking is rapid and ideally a simple process of isolation dilution. Put the loop in the flame and let it cool. Sterilization- autoclave 5.

Distribution in sterile petri dishes Distribution in plated media RAM architecture Founded Radiant Technologies, Inc in 1988. Each colony iscounted as a "colony forming unit" (CFU) containing microbial population of similar cells. RandyRotta PLUS. The streak plate method is a rapid qualitative isolation method. Radiant streak:the cells are inoculated at one end of the plate on the form of a thinsmear and the steaks are made radiating outwardly using a flame sterilized loop. Procedures described include (1) streak-plating bacterial cultures to isolate single colonies, (2) pour-plating and (3) spread-plating to enumerate viable bacterial colonies, (4) soft agar. Flame the loop and let it cool for 5 seconds. Answer : The streak plate method is more commonly used in order to obtain a pure culture and consists of the quadrant streak and the radiant streak which both involving streaking a loopful of organisms across an area of nutrient agar , this method also requires a higher skill level .
