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]
Microbial cultures on solid and liquid media. A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology.
mostly used for ELISA: Microtome: cuts prepared specimens for analysis under microscope Nichrome wire loop: used to inoculate test samples into culture media for bacterial or fungal cultures, antibiograms, etc.; sterilized by flaming to red hot before use Petri dish/agar plate: to act as a supporting container to hold the culture medium in
YEPD media is often used as a general growth media for yeasts like Saccharomyces cerevisiae and Candida albicans; Sporulation medium is medium used when spores have to be formed. It can also be used when working with fungi or bacteria depending on whether or not the strain is capable of forming spores.
LB medium bottle and LB agar plate Plate medium agar LB. Lysogeny broth (LB) is a nutritionally rich medium primarily used for the growth of bacteria. Its creator, Giuseppe Bertani, intended LB to stand for lysogeny broth, [1] but LB has also come to colloquially mean Luria broth, Lennox broth, life broth or Luria–Bertani medium. [2]
Comparison of two culture media types used to grow Neisseria gonorrhoeae bacteria. Known as overgrowth, note that the non-selective chocolate agar medium on the left, due to its composition, allowed for the growth of organismal colonies other than those of Neisseria gonorrhoeae, while the selective Thayer–Martin medium on the right, containing antimicrobials that inhibit the growth of ...
The medium must be incubated for a significant length of time, usually four weeks, due to the slow doubling time of M. tuberculosis (15–20 hours) compared with other bacteria. The medium is named after the Austrian pathologist Ernst Löwenstein (1878–1950) and the Danish medical doctor Kai Adolf Jensen (16.7.1894-2.5.1971).
Streak plates of several bacterial species on nutrient agar plates. Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms.
