  2. Confluency - Wikipedia

    en.wikipedia.org/wiki/Confluency

    In cell culture biology, confluence refers to the percentage of the surface of a culture dish that is covered by adherent cells.For example, 50 percent confluence means roughly half of the surface is covered, while 100 percent confluence means the surface is completely covered by the cells, and no more room is left for the cells to grow as a monolayer.

  3. Miles and Misra method - Wikipedia

    en.wikipedia.org/wiki/Miles_and_Misra_method

    The Miles and Misra Method (or surface viable count) is a technique used in Microbiology to determine the number of colony forming units in a bacterial suspension or homogenate. The technique was first described in 1938 by Miles, Misra and Irwin who at the time were working at the LSHTM. [1] The Miles and Misra method has been shown to be ...

  4. Bacterial growth - Wikipedia

    en.wikipedia.org/wiki/Bacterial_growth

    Bacterial growth curve\Kinetic Curve. In autecological studies, the growth of bacteria (or other microorganisms, as protozoa, microalgae or yeasts) in batch culture can be modeled with four different phases: lag phase (A), log phase or exponential phase (B), stationary phase (C), and death phase (D).

  5. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    Once the growth medium in the petri dish is inoculated with the desired bacteria, the plates are incubated at the optimal temperature for the growing of the selected bacteria (for example, usually at 37 degrees Celsius, or the human body temperature, for cultures from humans or animals, or lower for environmental cultures). After the desired ...

  6. Bacterial lawn - Wikipedia

    en.wikipedia.org/wiki/Bacterial_lawn

    A bacterial lawn used in antibiotic resistance testing. Bacterial lawn is a term used by microbiologists to describe the appearance of bacterial colonies when all the individual colonies on a Petri dish or agar plate merge to form a field or mat of bacteria. Bacterial lawns find use in screens for antibiotic resistance and bacteriophage titering.

  7. Bacterial patterns - Wikipedia

    en.wikipedia.org/wiki/Bacterial_patterns

    The formation of patterns in the growth of bacterial colonies has extensively been studied experimentally. Resulting morphologies appear to depend on the growth conditions. They include well known morphologies such as dense branched morphology (DBM) or diffusion-limited aggregation (DLA), but much complex patterns and temporal behaviour can be fou

  8. Monod equation - Wikipedia

    en.wikipedia.org/wiki/Monod_equation

    The Monod equation is a mathematical model for the growth of microorganisms. It is named for Jacques Monod (1910–1976, a French biochemist, Nobel Prize in Physiology or Medicine in 1965), who proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration of a limiting nutrient.

  9. Winogradsky column - Wikipedia

    en.wikipedia.org/wiki/Winogradsky_column

    This top layer of aerobic bacteria produces O 2 which feeds back into the column to facilitate further reactions. [1] While the Winogradsky column is an excellent tool to see whole communities of bacteria, it does not allow one to see the densities or individual bacterial colonies. It also takes a long time to complete its cycle.
