For example, organisms that can utilize a … Selective media are used to isolate a particular type of microorganism by giving a specific condition for the growth of that particular microorganism. Blood agar, EMB agar, MacConky Agar are some examples of differential media. 2. These are the Differential & Selective Bacterial Growth Media Lecture materials of the Virtual Microbiology Classroom.The resources below are used to supplement an … g) Sugar media. Selective / Differential / Enrichment media Selective media helps select for growth of certain organisms in a mixed population by using a ingredient that inhibits the growth of other microorganisms, but not the desired species or group. 2. It is the selective and differential medium for coliforms. Many different types of media are used to culture microorganisms. 1. Contains 7.5 % NaCl (salt) which inhibits the growth of most microorganisms, except Staphylococcus species. Key Terms. “Growth medium.” Wikipedia. EMB agar, Mannitol Salt agar, MacConkey agar, and Phenylethyl Alcohol (PEA) are examples of selective media. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. One of these techniques are a streak plate technique, which is when a bacterial mixture is transferred to the edge of an agar plate with an inoculating loop and streaked over the surface in one of several patterns. and L. casei from nine different commercial probiotic yoghurts. Examples of enriched media include sheep blood agar and chocolate (heated blood) agar. 3. Growing microbes is feasible only if they are provided with a suitable culture medium and other optimal growth conditions such as pH, and temperature. c) Selective media. Certain media work as both selective and differential media. Available here. N.p., n.d. Principle: Differential growth suppression Selective medium is designed to suppress the growth of some microorganisms while allowing the growth of others. The key difference between selective media and differential media is that selective media are used to grow and isolate a specific type of microorganism by suppressing the growth of other microorganisms while differential media are used to visually distinguish microorganisms from one another. For example: Selective media: YM agar selects for microbes that grow in low pH conditions such as yeasts and molds. Selective media and differential media are two types of growth media. for the inhibition of unwanted microorganisms. “E.coli-fields” By Carmen Moreno González – Own work (CC BY-SA 4.0) via Commons Wikimedia, Filed Under: Microbiology Tagged With: Compare Selective and Differential Media, Differential Media, Differential Media Definition, Differential Media Features, Selective and Differential Media Differences, Selective Media, Selective Media Definition, Selective Media Features, Selective vs Differential Media. Selective and Differential Media for Identifying Microorganisms (Theory): Microbiology Virtual Lab I: Biotechnology and Biomedical Engineering: Amrita Vishwa Vidyapeetham Virtual Lab. This is the difference between selective media and differential media. BASAL MEDIA. What are Selective Media Selective media contain ingredients that inhibit the growth of some organisms but allow others to grow. when agar adds to nutrient broth, it becomes nutrient agar. Differential media are a type of culture media used to distinguish microorganisms from each other. Selective and differential media are two types of growth media used to isolate and identify microorganisms. 1. 100% found this document useful (5 votes), 100% found this document useful, Mark this document as useful, 0% found this document not useful, Mark this document as not useful, Save Selective, Differential, & Enriched Media Lab Char... For Later, Selective, Differential, and Enriched Media, while inhibiting growth of other organisms,  – Contains chemical that produce a change in the, often provide carbs., yield acidic end product,  – Contains substance nutrients that encourages the, of organisms, Including: fastidious organisms. 5. Blood Agar (BAP) is another type of differential medium. Selective media is often used when one is trying to isolate a specimen of interest from a mixed culture. A variety of selective and differential media are used in various types of microbiology laboratories. Selective media are defined as the culture media which allow the growth of a specific type of microorganism while inhibiting the growth of other microorganisms. They are formulated to isolate and identify a particular type of microorganism. Web. Differential media are the culture media designed to distinguish microorganisms from one another by visible growth characteristics. Nutrient broth is an example of simple medium. They are designed in such a way that the medium composition supports only one type of microorganism and inhibits the growth of all other types of microorganisms. Non selective media for primary isolation (Blood Agar) Selective or differential agar (e.g. microorganisms. However, in limiting the growth of organisms in an experiment to only specific types, scientists also eliminate the possibility of understand… It is not selective, and will grow many different types of microbes. Selective and differential media is extremely useful when examining mixed bacterial cultures since it provides: a simple way to "screen out" certain bacterial species some biochemical information on the organisms present in the culture (presumptive identification) Media can be Selective and Differential TOT Zoo Add Page Insert Table Chart Text Shape Media Comment These questions will serve in lieu of a lab report for Exercise 15, 16, and 17 You will find the answer to these questions in the background, procedure, results and interpretation sections of manual Exercise 15, 16, and 17, videos, Actions of Selective and Differential Media Chart, and the Principle/Theory article in homework section.) Compare the Difference Between Similar Terms. Differential media are designed by targeting the biochemical properties of the targeted microorganisms. Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms. Differential media typically display some type color change in the presence of certain bacteria. Available here. YM (yeast extract, malt extract agar) has a low pH, deterring bacterial growth. a. 51490: Hektoen Enteric Agar for microbiology, NutriSelect ™ Plus : Hektoen enteric agar is a type of primary standard media, which may be commonly used in the selective detection and isolation of Salmonella in food microbiology labs and in human stool specimens. This is the difference between selective media and differential media. Please download PDF version here Difference Between Selective and Differential Media. the same results would be found in MacConkey agar because both media are selective and differential for gram-negative organisms. Differentiates Staphylococcus aureus (+) from other Staphylococcus species. There are different types of media available for the culturing purpose. Some media are both differential and selective. Specific inhibitors also can be included into media at various concentrations to suppress the growth of nonspecific microorganisms. Selective media = Media providing a means of isolating a particular species or type or microorganisms, while inhibiting the growth of others (e.g., EMB, MAC, T-7, MSA, etc.). 1. Side by Side Comparison – Selective vs Differential Media in Tabular Form It indicates only if the target microorganism is present in the medium by showing a different growth pattern or visible change. Culture media are used to grow, isolate, differentiate and identify microorganisms. Selective media allow the growth of a specific type of microorganisms and inhibit the rest of the other microorganisms. Dr.Samanthi Udayangani holds a B.Sc. Some Examples of Selective and Differential Media: Mannitol Salt Agar (MSA) Mannitol Salt Agar (MSA) is a selective medium for the isolation of pathogenic and non-pathogenic It contains peptone water and meat extract 1%. Thus, the phrase recombinant DNA refers to an organism created in the lab by adding DNA from another species. Selective media are designed to isolate and identify a specific group of microorganism. While these are just a few examples of how types of media can help microbiologists distinguish between microbes, there are many other types of selective and differential media. Selective and Differential Media. Intended Use. Summary. The difference between selective and differential media is mainly due to the following factors: Intended use of the media: The purpose of both selective and differential media differs.A selective media only permits the development of particular organisms, while a differential media discerns one species of the organism from the other growing on the similar substrate.
