  • A culture medium is any material prepared for the growth of bacteria in a laboratory. Microbes that grow and multiply in or on a culture medium are known as a culture. Agar is a common solidifying agent for a culture medium.
  • Agar is a gel at room temperature, remaining firm at temperature as high as 65C. Agar melts at approximately 85C, a different temperature from that at which it solidifies, 32-40C. This property is known as hysteresis. Agar is generally resistant to shear forces; however, different agars may have different gel strengths or degrees of stiffness.
  • Agar is typically used in a final concentration of 1-2% for solidifying culture media. Smaller quantities (0.05-0.5%) are used in media for motility studies (0.5% w/v) and for growth of anaerobes (0.1%) and microaerophiles.
  • Specifications for bacteriological grade agar include good clarity, controlled gelation temperature, controlled melting temperature, good diffusion characteristics, absence of toxic bacterial inhibitors and relative absence of metabolically useful minerals and compounds.
  • Blood agar plate (BAP) Contains mammalian blood (usually sheep or horse), typically at a concentration of 510%. BAP are an enriched, differential media used to isolate fastidious organisms and detect hemolytic activity. β-hemolytic activity will show complete lysis of red blood cells surrounding colony, while α-hemolysis will only partially lyse hemoglobin and will appear green. γ-hemolysis (or non-hemolytic) is the term referring to a lack of hemolytic activity.
  • Blood agar is used to support the growth of fastidious organisms and to determine the type of hemolysis (destruction of red blood cell walls) an organism produces.
  • CDC Anaerobic Blood Agar is an enriched medium for the growth and partial identification of obligate anaerobes. It also supports good growth of aerobic, facultative anaerobic and microaerophilic organisms found in clinical materials if incubated under the appropriate conditions.
  • Tryptose Agar is used for cultivating a wide variety of fastidious microorganisms, particularly for isolating Brucella. Tryptose Agar with 5% bovine serum, with or without antibiotics, remains a standard plating medium for the isolation of brucellae. For isolation of Brucella stains from contaminated milk, crystal violet (gentian violet) can be added to Tryptose Agar to suppress gram-positive organisms. Tryptose media can be supplemented with thiamine or citrate for the cultivation and maintenance of fastidious aerobic and facultative microorganisms.
  • Coagulase Mannitol Agar is used for the differentiation of Staphylococcus aureus from other species based on coagulase production and mannitol utilization. Coagulase Mannitol Agar aids in the differentiation of staphylococci by indicating the presence of coagulase and the utilization of mannitol. Coagulase production is dependant on the presence of mannitol, a protein factor in the brain heart infusion and blood serum (plasma). During utilization of the mannitol, the pH of the medium drops, causing the bromcresol purple indicator to change from purple to yellow and producing yellow zones around these colonies. An opaque area of coagulated plasma forms around the colonies of organisms that also produce coagulase.
