All-Purpose media support the growth of a multitude of organisms. Some examples are tryptic soy broth (TSB) and nutrient agar. 

All-Purpose Media

Enriched media is a type of specialized media that contains extra nutrients such as growth factors, vitamins to promote the growth of fastidious organisms.

Enriched Media

A chemically defined media is one where all of the chemical components of the media are known and defined, such as EZ medium. 

Chemically Defined Media 

A complex media is a media that contains undetermined and variable components because it is obtained from extracts and digests of yeasts, meat, or plants. Some examples are nutrient broth, tryptic soy broth (TSB), and brain heart infusion.

Complex Media

Selective media target the growth of specific organisms by supplying important nutrients and suppressing the growth of competitive, undesirable organisms. 

Selective Media

Differential media are used to distinguish colonies of different organisms based on the change in color of the media or colony.

Growth media, also known as nutritional media, are used to grow microorganisms in a laboratory setting and can be liquid, solid, or gel-like. A growth medium provides essential nutrients for microorganisms to grow and reproduce, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract). The ingredients in a growth medium can be modified to cultivate unique types of microorganisms.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
