  • 1. 17: MSA, MacConkey, EMB Plates - Biology LibreTexts
    Differential media allow one to differentiate between types of organisms growing on the plate because each has a distinct appearance based on whether or not it is carrying out a particular biochemical reaction
  • Phenylethyl Alcohol Agar: Composition, Preparation, Uses
    Phenylethyl alcohol agar (PEA) is a selective medium used to cultivate Gram-positive organisms, particularly cocci, from a sample containing a mixture of pathogens The active ingredient, phenylethyl alcohol, inhibits or markedly reduces the growth of Gram-negative organisms by interfering with DNA synthesis
  • Specimen Type and Culture Media Table
    The selection of culture media to plate is based on the human body site of the infection and the suspected microorganism causing the infection The table below provides examples of recommended media that can be plated to recover microorganisms from a particular body site
  • Media Types - Microbiology learning: The whyology of microbial testing
    This plate is incubated in the CO2 incubator and should be slightly opened to enable a higher amount of CO2 to enter and enhance the growth of this fastidious organism
  • Phenylethyl Alcohol Agar Protocol
    Most gram-positive and gram-negative anaerobes grow on PEA agar medium, especially in mixed culture, and morphology of colonies is similar to that on blood agar plates, however, a longer incubation time is necessary to detect the more slowly growing and pigmented anaerobes (7)
  • Types Of Agar Plates - Sciencing
    After planting initial microorganisms on the gelatinous surface of the plate, researchers incubate them at body temperature to form colonies for isolation and analysis Agar plates come with many different types of media or nutrients, depending on the microorganism you want to culture
  • Phenylethyl Alcohol Blood Agar – PEA - PEA - Anaerobe Systems
    Morphology of the colonies on PEA are similar to those found on enriched blood agar plates, like Brucella Blood Agar PEA agar is especially useful in the selective isolation of anaerobes from mixed populations that contain rapidly growing gram-negative bacteria such as Proteus species
  • MacConkey Agar- Composition, Principle, Uses, Preparation and Colony . . .
    Incubation of MacConkey Agar plates under increased CO2 has been reported to reduce growth and recovery of a number of strains of Gram-negative bacilli Some strains of Proteus may swarm on this medium
  • BD BBL™ Prepared Plated Media
    BD BBL™ prepared plated media enables the isolation of microorganisms from samples or specimens Ready for immediate use, they are routinely available in several types of Petri-style dishes, containing a variety of media
