Schädler agar
From Wikipedia, the free encyclopedia
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] The medium contains a combination of peptones, yeast extract, and other nutrients that create an optimal growth environment. Additionally, reducing agents such as cysteine and sodium thioglycolate are included to maintain the anaerobic conditions necessary for the survival of these bacteria.
Schädler agar is composed of several key ingredients that provide the necessary nutrients and environment for anaerobic bacterial growth:[2]
- Peptones: serve as a source of nitrogen and amino acids.
- Yeast extract: provides vitamins, particularly B vitamins, and other growth factors.
- Dextrose: a source of carbon and energy.
- Sodium chloride: maintains osmotic balance.
- L-Cysteine: acts as a reducing agent to create anaerobic conditions.
- Sodium thioglycolate: another reducing agent that helps maintain anaerobic conditions.
- Agar: a solidifying agent that provides a firm surface for bacterial growth.
