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.
Microbial cultures on solid and liquid media
A culture of Bacillus anthracis
Liquid cultures of the cyanobacterium Synechococcus PCC 7002
Multitarget microbial panel. A small amount of the bacteria to be tested is placed in each well, each of which has the ingredients for a separate test.
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 or small plants like the moss Physcomitrella patens. Different types of media are used for growing different types of cells.
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.
