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.

However, Mueller Hinton agar is made up of a couple of components, including beef extract, acid hydrolysate of casein, and starch, as well as agar to solidify the mixture. The composition of Mueller Hinton agar can vary depending on the manufacturer and the intended use, but the medium is generally nutrient-rich and free of inhibitors that ...
The complete medium, with OADC enrichment and PANTA antibiotic mixture, is one of the most commonly used liquid media for the cultivation of mycobacteria. All types of clinical specimens, pulmonary as well as extra-pulmonary (except blood and urine ), can be processed for primary isolation in the MGIT tube using conventional methods.
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".
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 .
Middlebrook broth is commonly used in the preparation of inocula for antimicrobial assays, biochemical tests (arylsufatase and tellurite reduction), and maintenance of stock strains. Additionally, 7H9 broth is used as a medium in the mycobacteria growth indicator tube .
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]
Various types of flavored gulaman sold in plastic cups. Gulaman is now the chief Filipino culinary use of agar, which is made of processed Gracilaria seaweed (around 18 species occur naturally in the Philippines); [2] [7] or carrageenan derived from other farmed seaweed species like Eucheuma and Kappaphycus alvarezii, which were first cultivated commercially in the Philippines.
