- Definition method of direct plate counting that consists of evenly spreading the diluted sample over an agar plate Reference "Virginia Tech > Filebox > Direct Plate Counting > Soil Microbiology > Allen Coleman, http://filebox.vt.edu/users/chagedor/biol_4684/Methods/platecounts.html (26.8.2009)"
- Comment used to count the number of cells in a sampleThis method yields colonies that form on the surface of the agar.In this method the mixed culture of microorganisms is not diluted in the melted agar medium (unlike the pour plate method); it is rather diluted in a series of tubes containing sterile liquid, usually, water or physiological saline. A drop of so diluted liquid from each tube is placed on the centre of an agar plate and spread evenly over the surface by means of a sterilized bent-glass-rod.
