  2. Agar plate - Wikipedia

    en.wikipedia.org/wiki/Agar_plate

    Contamination on an agar plate. An agar plate is a Petri dish that contains a growth medium solidified with agar, used to culture microorganisms. Sometimes selective compounds are added to influence growth, such as antibiotics. [1] 96 pinner used to perform spot assays with yeast, fungal or bacterial cells

  3. Colonial morphology - Wikipedia

    en.wikipedia.org/wiki/Colonial_morphology

    When a specimen arrives in the microbiology laboratory, it is inoculated into an agar plate and placed in an incubator to encourage microbial growth. Because the appearance of microbial colonies changes as they grow, colonial morphology is examined at a specific time after the plate is inoculated.

  4. Plate count agar - Wikipedia

    en.wikipedia.org/wiki/Plate_count_agar

    Once a plate has been successfully prepared, plate count agar cells will grow into colonies which can be sufficiently isolated to determine the original cell type. The colony-forming unit (CFU) is an appropriate description of the colony's origin. In plate counts, colonies are counted, but the count is usually recorded in CFU.

  5. Growth medium - Wikipedia

    en.wikipedia.org/wiki/Growth_medium

    An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2]

  6. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    The streak plate method is a way to physically separate the microbial population, and is done by spreading the inoculate back and forth with an inoculating loop over the solid agar plate. Upon incubation, colonies will arise and single cells will have been isolated from the biomass. Once a microorganism has been isolated in pure culture, it is ...

  7. Candida (fungus) - Wikipedia

    en.wikipedia.org/wiki/Candida_(fungus)

    Agar plate culture of C. albicans. When grown in a laboratory, Candida appears as large, round, white or cream (albicans means "whitish" in Latin) colonies, which emit a yeasty odor on agar plates at room temperature. [13]

  8. Colony-forming unit - Wikipedia

    en.wikipedia.org/wiki/Colony-forming_unit

    Colony-forming units are used to quantify results in many microbiological plating and counting methods, including: The pour plate method wherein the sample is suspended in a Petri dish using molten agar cooled to approximately 40–45 °C (just above the point of solidification to minimize heat-induced cell death).

  9. Talaromyces marneffei - Wikipedia

    en.wikipedia.org/wiki/Talaromyces_marneffei

    Plating samples out onto two Sabouraud agar plates, then incubating one at 30 °C and the other at 37 °C, should result in two different morphologies. A mold-form will grow at 30 °C, and a yeast-form at 37 °C. Mycelial colonies will be visible on the 30 °C plate after two days. Growth is initially fluffy and white and eventually turns green ...
