List of culture media used in microbiology



MacConkey Agar

MacConkey Agar, developed by Alfred Theodore MacConkey 1900 , is a selective and differential agar that only cultivates gram-negative bacterial species, it can further differentiate Gram-negative organisms based on their lactose metabolism ...

Mueller Hinton Agar

It was originally formulated by Mueller and Hinton as a protein-free medium for the primary isolation of Neisseria species. Mueller Hinton Agar is a standardized solid medium recommended for the study of the susceptibility of bacteria to antimicrobial agents by the method of diffusion .. ...

Nutrient agar

With a relatively simplified composition, nutrient agar provides the nutrients necessary for the growth of a wide range of microorganisms, it is used for the culture of bacteria and for the enumeration of organisms in water, wastewater, urine, feces and other materials....

Nutrient broth

Nutrient Broth is a medium widely used for the culture of undemanding microorganisms. It is recommended in many standardized methods of analysis of foods, dairy products, water and other products. Nutrient Broth has the same formulation as Nutrient Agar, only agar has been omitted (which causes the medium to solidify at room temperature).....

XLD Agar

XLD Agar (Xylose Lysine Deoxycholate Agar) is a moderately selective differential medium used for the isolation and differentiation of enteric gram-negative pathogens, particularly salmonella and shigella in clinical, environmental and food samples. ....

Bromocresol purple lactose agar

Bromocresol purple lactose agar, BCP Agar, is a lactose-based, differential, non-selective medium used for the detection and isolation of Enterobacteriaceae. It (also) makes it possible to differentiate the species fermenting lactose from those which do not ferment it.

DNAse test agar

Deoxyribonuclease (DNase) test is used to determine an organism's ability to hydrolyze DNA and use it as a source of carbon and energy for growth. Used mainly to differentiate Staphylococcus aureus from other Staphylococci.

Trypticase Soy Agar

Tryptone Soy Agar, Tryptone Soy Agar (TSA), or (TSB), called Soybean-Casein Digest Agar Medium by the United States Pharmacopeia is a general-purpose nonselective growth medium that supports the growth of most Gram bacteria. -negative and non-fastidious Gram-positive as well as many yeasts and moulds.

BEA agar

Bile Aesculin Agar, BEA Agar, is a selective and differential medium. This medium tests the ability of organisms to hydrolyze esculin in the presence of bile. It is commonly used to identify members of the genus group D streptococci and enterococci........

PCA agar

PCA agar (Plate Count Agar) is a medium recommended for the standardized enumeration of aerobic bacteria in water, dairy products and foods, cosmetics or pharmaceuticals..........

LB broth

LB Broth , also known as LB Medium, Lysogenia Broth, Luria Broth or Luria-Bertani medium, is a nutrient-rich medium commonly used for the cultivation of bacteria...........

VRBL agar

VRBL Agar is a selective medium for the isolation and enumeration of coliforms in water, milk and other dairy products, dairy equipment and other foodstuffs. ...........

Hugh Leifson medium (M.E.V.A.G)

To study the pathway of attack of a carbohydrate, media containing a only carbohydrate and a pH indicator...........

Thioglycolate broth

Thioglycolate broth is a general-purpose medium for the cultivation of anaerobes, microaerophiles and aerobes, and is recommended as one of the media for sterility testing of biological products............

Brucella agar
