  2. Plate count agar - Wikipedia

    en.wikipedia.org/wiki/Plate_count_agar

    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.

  3. Replica plating - Wikipedia

    en.wikipedia.org/wiki/Replica_plating

    Negative selection through replica plating to screen for ampicillin sensitive colonies. Replica plating is a microbiological technique in which one or more secondary Petri plates containing different solid (agar-based) selective growth media (lacking nutrients or containing chemical growth inhibitors such as antibiotics) are inoculated with the same colonies of microorganisms from a primary ...

  4. Streaking (microbiology) - Wikipedia

    en.wikipedia.org/wiki/Streaking_(microbiology)

    A plate which has been streaked showing the colonies thinning as the streaking moves clockwise. In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria.

  5. Boilerplate text - Wikipedia

    en.wikipedia.org/wiki/Boilerplate_text

    In contract law, the term "boilerplate language" or "boilerplate clause" describes the parts of a contract that are considered standard.A standard form contract or boilerplate contract is a contract between two parties, where the terms and conditions of the contract are set by one of the parties, and the other party has little or no ability to negotiate more favorable terms and is thus placed ...

  6. Fenske equation - Wikipedia

    en.wikipedia.org/wiki/Fenske_equation

    Fractionation at total reflux. The Fenske equation in continuous fractional distillation is an equation used for calculating the minimum number of theoretical plates required for the separation of a binary feed stream by a fractionation column that is being operated at total reflux (i.e., which means that no overhead product distillate is being withdrawn from the column).

  7. 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]

  8. Petri dish - Wikipedia

    en.wikipedia.org/wiki/Petri_dish

    A Petri dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured, [1] [2] originally, cells of bacteria, fungi and small mosses. [3] The container is named after its inventor, German bacteriologist Julius Richard Petri.

  9. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    The first culture media was liquid media, designed by Louis Pasteur in 1860. [2] This was used in the laboratory until Robert Koch's development of solid media in 1881. [ 3 ] Koch's method of using a flat plate for his solid media was replaced by Julius Richard Petri's round box in 1887. [ 2 ]
