Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms. It typically contains (mass/volume): [1] 0.5% peptone – this provides organic nitrogen; 0.3% beef extract/yeast extract – the water-soluble content of these contribute vitamins, carbohydrates, nitrogen, and salts; 1.5% agar ...
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.

YM Agar and Broth, is a selective growth medium with low pH useful for cultivating yeasts, molds, or other acid-tolerant or acidophilic organisms, while deterring growth of most bacteria and other acid intolerant organisms. [1] It is malt extract medium modified by the addition of yeast extract and peptone. [2]
Stock and broth are loaded with nutrients. Learn the differences, benefits and if one is better than the other, plus recipes and store bought recommendations.
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]
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 ...
Schädler agar is a nutrient-rich growth medium primarily used in microbiology for the cultivation of anaerobic bacteria. It was developed to support the growth of a wide variety of anaerobic organisms, providing a conducive environment for both fastidious and non-fastidious anaerobes . [ 1 ]
This nutrient-rich microbial broth contains peptides, amino acids, water soluble vitamins and glucose in a low-salt formulation. It was developed by Douglas Hanahan in 1983 and is an adjusted version of the commonly used LB medium (lysogeny broth). Growth of E. coli in SOB or SOC medium results in higher transformation efficiencies of plasmids.
