The pour plate technique is the typical technique used to prepare plate count agars. Here, the inoculum is added to the molten agar before pouring the plate. The molten agar is cooled to about 45 degrees Celsius and is poured using a sterile method into a petri dish containing a specific diluted sample.
Brain heart infusion media made from Difco powdered media. Brain heart infusion (BHI) is a growth medium for growing microorganisms. It is a nutrient-rich medium, and can therefore be used to culture a variety of fastidious organisms.
Eaton's agar is a type of agar media is used to grow Mycoplasma pneumoniae. One recipe for the cultivation of M. pneumoniae (Eaton's agar) includes : [1] 70% Difco PPLO (pleuropneumonia-like organism) agar or broth base; 20% unheated horse serum; 10% fresh aqueous extract of baker's yeast; 1000 units/ml Penicillin G
De Man–Rogosa–Sharpe agar, often abbreviated to MRS, is a selective culture medium designed to favour the luxuriant growth of Lactobacilli for lab study. Developed in 1960, this medium was named for its inventors, Johannes Cornelis de Man [ Wikidata ] , Morrison Rogosa [ Wikidata ] , and Margaret Elisabeth Sharpe [ Wikidata ] .
Mueller Hinton agar is commonly used in the disk diffusion method, which is a simple and widely used method for testing the susceptibility of bacterial isolates to antibiotics. In this method, small disks impregnated with different antibiotics are placed on the surface of the agar, and the zone of inhibition around each disk is measured to ...
To enumerate the growth, bacteria can be suspended in molten agar before it becomes solid, and then poured into petri dishes, the so-called 'pour plate method' which is used in environmental microbiology and food microbiology (e.g. dairy testing) to establish the so-called 'aerobic plate count'.
The spread plate method wherein the sample (in a small volume) is spread across the surface of a nutrient agar plate and allowed to dry before incubation for counting. [11] The membrane filter method wherein the sample is filtered through a membrane filter, then the filter placed on the surface of a nutrient agar plate.
Baird-Parker agar is a type of agar used for the selective isolation of gram-positive Staphylococci species. [1] It contains lithium chloride and tellurite to inhibit the growth of alternative microbial flora, while the included pyruvate and glycine promote the growth of Staphylococci . [ 1 ]
