Differential media typically display some type color change in the presence of certain bacteria. Synonym. It is not selective, and will grow many different types of microbes. Selective media is designated for the growth of one type of organism. Many are significant pathogens, such a coli, Salmonella, Shigella, but many compose our normal flora and inhabit soil and water. Differential media is like blood agar, which is an organism in itself, but seeks to destroy another one (hemoglobin). Cards. Selective medium is agar-based (solid) medium so that individual colonies may be isolated. Combining the two can often eliminate having to perform multiple cultures, saving time and money for the microbiologist. Differential Media These two types of media can – often in a single step – give a preliminary ID for an infectious organism Selective! No Chapter. EMB contains dyes that are toxic to Gram-positive bacteria. YM (yeast extract, malt extract agar) has a low pH, deterring bacterial growth. DNase agar is a differential medium that tests the ability of an organism to produce an exoenzyme, called deoxyribonuclease (DNase) that hydrolyzes DNA. ; MacConkey agar is for Gram-negative bacteria. Blood agar medium is, however, differential.

Bingo. Some media are both differential and selective. E salts contain only MgSO4, K2HPO4, Na2NH4PO4, and citric acid, and therefore, in order to grow, an organism must be prototrophic (capable of synthesizing, opposite is auxotrophic) for all necessary molecules such as amino acids, updated 5 years ago by mmiyakooo. From history and the arts to travel and fashion, we take a broad look at culture in the context of sustainability. Study Flashcards On Microbiology: Lab Exercise 10-Selective, Enriched and Differential Media at Cram.com. A differential medium support the growth of any microbe but distinguishes them based on how they metabolize or change the medium. Eosin methylene blue (EMB, also known as "Levine's formulation") is a selective stain for Gram-negative bacteria. While differential media are used to differentiate closely related organisms or groups of organisms. These media are non selective and they contain general nutrients which required for the growth of wide range of microorganisms. Differential media are those media which are used to distinguish closely related microorganisms based on their morphology on different agar media. Differential media contain compounds that allow groups of microorganisms to be visually distinguished by the appearance of the colony or the surrounding media, usually on the basis of some biochemical difference between the two groups. COPY. So, media could be both selective as well as differential. Differential and selective media are commonly used in microbiology laboratories. The selectivity is accomplished in several ways.
