  2. Agar plate - Wikipedia

    en.wikipedia.org/wiki/Agar_plate

    Thus, the plate can be used either to estimate the concentration of organisms in a liquid culture or a suitable dilution of that culture using a colony counter, or to generate genetically pure cultures from a mixed culture of genetically different organisms. Several methods are available to plate out cells. One technique is known as "streaking".

  3. Axenic - Wikipedia

    en.wikipedia.org/wiki/Axenic

    Axenic cultures of microorganisms are typically prepared by subculture of an existing mixed culture. This may involve use of a dilution series, in which a culture is successively diluted to the point where subsamples of it contain only a few individual organisms, ideally only a single individual (in the case of an asexual species).

  4. Streaking (microbiology) - Wikipedia

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

    Bacteria frequently occur in mixed populations. It is very rare to find a single occurring species of bacteria. To be able to study the cultural, morphological, and physiological characteristics of an individual species, it is vital that the bacteria be divided from the other species that generally originate in the environment.

    Their population is composed of approximately 68% mestizo, which means of mixed race. [123] Venezuelan culture is mainly composed of a mixture of their indigenous culture, Spanish, and African. [124] There was a heavy influence of Spanish culture due to the Spanish Conquest, which influenced their religion, language and traditions.

  6. Growth medium - Wikipedia

    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.

  8. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    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 .

    The bacterial culture is mixed in, and a warm temperature of 30–45 °C (86–113 °F) is maintained for 4 to 12 hours to allow fermentation to occur, with the higher temperatures working faster but risking a lumpy texture or whey separation. [4] [5]
