What is a general purpose media and when should it be used?
General Purpose Media. Media that provides enough nutrients in which most any microorganism will utilize for growth.

General Purpose Media. Media that provides enough nutrients in which most any microorganism will utilize for growth. Allows for a wide variety of microorganisms to grow (typically agar plus nutrients) Ex: Soy Agar.Click to see full answer. Beside this, what are general purpose media?Examples of standard general purpose media that will support the growth of a wide variety of bacteria include nutrient agar, tryptic soy agar, and brain heart infusion agar. Blood agar is one type of differential medium, allowing bacteria to be distinguished by the type of hemolysis produced.One may also ask, what is the purpose of using selective media? Selective and differential media are used to isolate or identify particular organisms. Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms. Differential media are used to differentiate closely related organisms or groups of organisms. Secondly, what is the purpose of using different types of agar? Types of agar plates[edit] Chocolate agar – this contains lysed blood cells, and is used for growing fastidious (fussy) respiratory bacteria. Neomycin agar – contains the antibiotic neomycin. Sabouraud agar – used for fungi. It contains gentamicin and has a low pH that will kill most bacteria.What is the best medium for the growth of bacteria?Tryptic Soy Agar (TSY) is a good all-purpose medium commonly used to grow bacteria in the microbiology laboratory. For example MacConkey’s Agar (MAC) is used to cultivate Gram-negative bacteria, by discouraging the growth of Gram-positive bacteria through the use of crystal violet dyes and bile salts.
