Anaerobic Culture Media used in anaerobic bacteriology may be prepared in a fresh manner or bought from commercial vendors.
Media for anaerobic fermentation that is created in the laboratory should be used within two weeks after the time of preparation, as prolonged storage can degrade the quality of the medium due to peroxide accumulation and dehydration.
Lowenstein Jensen Medium (LJ Medium) is a highly selective medium.
Solid media that are used to isolate as well as cultivation of Mycobacteria can be egg-based or Agar-based.
Potato Dextrose Agar (PDA) is commonly abbreviated as PDA.
Potato Dextrose Agar has been suggested by APHA and F.D.A.for the count of moulds and yeasts during the testing of food items and dairy products.
Chocolate Agar (CAP or CHOC) is a nonselective enhanced medium that is used to identify and isolate of pathogens that are fastidious.
Xylose Lysine Deoxycholate agar (XLD) is a selective medium that allows for the isolation and growth of Salmonella and Shigella species using clinical samples or food. Taylor developed XLD Agar to aid in the differentiation, isolation and identification of enteric disease agents and support the growth more specialized enteric organisms. XLD Agar is a well-proven medium that allows the growth of Shigella species. It is also an excellent medium to isolate Salmonella species. It has a pH value of 7.4, giving it a bright pink to red color due to the indicator phenol.
Mannitol Salt Agar (MSA) is utilized as a differential and selective medium to isolate and detect Staphylococcus aureus in clinical and non-clinical samples. It is recommended for identification and enumeration of coagulase positive Staphylococci that are present in milk, food as well as other specimens. MSA also promotes an increase in the number of particular group of specific bacteria, while limiting the growth of other bacteria.
NYC Agar Base medium was initially created by Fauer, Weisburd and Wilson at the New York City Department of Health to isolate the pathogenic Neisseria strains from human samples. NYC medium, designed primarily to isolate pathogenic Neisseria is also able to support the growth of mycoplasmas with large colonies or mycoplasmas T (Ureaplasma). It is a translucent medium, highly selective, allowing direct microscopic observations and presumed identification of mycoplasmas and Neisseria gonorrhoeae.

Peptone Water is a type of broth medium. This media is mainly used to grow the organism and is also used as a base for determining carbohydrate fermentation patterns of non-fastidious organisms. It is also used to detect indole production by the organism.
Clinical materials containing small numbers of Vibrio should be inoculated into an enrichment medium prior to plating onto a selective medium, such as TCBS Agar (M189). Alkaline Peptone Water is a suitable enrichment broth for this purpose.
