Agar - Wikipedia
An agar plate or Petri dish is used to provide a growth medium using a mix of agar and other nutrients in which microorganisms, including bacteria and fungi, can be cultured and observed under the microscope. Agar is indigestible for many organisms so that microbial growth does not affect the gel used and it remains stable.
Bacterial Culture Media: Classification, Types, Uses
Any agar media can be selective by adding specific inhibitory agents that don’t affect the pathogen of interest. Various approaches to making a medium selective include addition of antibiotics, dyes, chemicals, alteration of pH, or a combination of these.
2.1: Introduction Growth Media - Biology LibreTexts
Jun 16, 2021 · There are two commonly used physical forms of growth media: liquid media and solid growth media. A liquid medium is called a broth (image 2). Solid growth media usually contains agar (image 1), which is a mixture of polysaccharides derived from red algae.
1.2: Media Preparation - Biology LibreTexts
Define medium/media. Tell that microbes require nutrients to grow in the laboratory. Differentiate between broth, slant, deep, and petri plate. Calculate the amount of medium powder required to make a specific volume of medium. Successfully prepare microbiological media.
Bacteriological Agar: Properties and Uses - Microbe Online
In the Microbiology lab, agar is the most commonly used growth medium for microorganisms. Agar media is essential for isolating and identifying microorganisms/pathogens from various samples. Agar is one of the most common basic media for gel electrophoresis, gel bead chromatography, and size exclusion chromatography.
6.3A: Culture Media - Biology LibreTexts
Dec 24, 2022 · Culture medium or growth medium is a liquid or gel designed to support the growth of microorganisms. There are different types of media suitable for growing different types of cells. Here, we will discuss microbiological cultures used for growing microbes, such as bacteria or yeast.
Nutrient Agar: Composition, Preparation and Uses
Aug 10, 2022 · Nutrient Agar is a general purpose, nutrient medium used for the cultivation of microbes supporting growth of a wide range of non-fastidious organisms. Nutrient agar is popular because it can grow a variety of types of bacteria and fungi, and contains many nutrients needed for the bacterial growth.
