What are Differential Media However, in limiting the growth of organisms in an experiment to only specific types, scientists also eliminate the possibility of understand… Differential Bacterial Growth Media. Blood agar, EMB agar, and MacConky agar are examples of differential media. Differential media are designed to differentiate microorganisms from one another. 0000001246 00000 n The main difference between selective and differential media is their role in the identification of microorganisms. Some media can be both selective and differential. Eukaryotic cells can also be grown in selective media. Selective media use specific growth characteristics of a microorganism to selectively grow that microorganism in the growth medium.

Selective Media: Selective media refer to a type of growth media that allows the growth of selected microorganisms in the medium. 0000052194 00000 n The selectivity is accomplished in several ways. 1. Selective Media: Selective media only allow the growth of a single microorganism in the medium. The selective media for eukaryotic cells commonly contain neomycin. A growth medium or culture medium is a solid, liquid or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation, or small plants like the moss Physcomitrella patens.

There are different types of media available for the culturing purpose.
Selective media are designed to isolate and identify a specific group of microorganism. Degree in Plant Science, M.Sc. Differential media distinguish the microorganisms by allowing them to produce visible growth pattern or different characteristics on the media. 1.
Selective media allow the growth of a specific type of microorganisms and inhibit the rest of the other microorganisms. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. A variety of selective and differential media are used in various types of microbiology laboratories.

1. A selective media is composed of specific ingredients to inhibit the growth of certain species of microbes in a mixed culture while allowing others to grow. For example, if a particular microbe has the ability to utilize a specific sugar type, a selective medium for that particular microbe can be prepared by making that specific sugar type as the only carbon source available in the medium.
for the inhibition of unwanted microorganisms. Growing microbes is feasible only if they are provided with a suitable culture medium and other optimal growth conditions such as pH, and temperature. 0000054500 00000 n Differential media refer to a type of growth media that allows the differentiation of closely-related microorganisms.

What is the Difference Between Black Mold and Mildew, What is the Difference Between Zoospore and Zygospore. Web. The selectivity of the medium can be achieved by employing several methods and by adding certain inhibitors to the medium.
Selective media are used for the growth of only selected microorganisms. Hence, selective media contain antimicrobials, dyes, alcohols, etc.
The advantage of using selective media is the ability to control what will and will not grow on a particular culture plate or petri dish. Differential Media: Differential media are used to identify and differentiate closely-related microorganisms. Media are included with necessary nutrients for the growth of microorganisms. Selective media refer to a type of growth media that allows the growth of selected microorganisms in the medium. 0000001374 00000 n 0000051750 00000 n
Differential media is also known as indicator media. Figure 02: Differential medium – E Coli characteristic colonies on EMB agar. Differential media contain nutrients which are utilized differently by microbes and generally do … Selective Media: Selective media do not use indicators.
Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms. Selective media and differential media are two important and commonly used media types among them.
Some examples of selective media are shown in the table below.
06 June 2017. Summary. Differential media are designed by targeting the biochemical properties of the targeted microorganisms. The main difference between selective and differential media is that selective media are used to isolate a particular strain of microorganisms whereas differential media are used to identify and differentiate a closely-related group of microorganisms. Certain media work as both selective and differential media.
This gives biologists the ability to control what types of organisms grow in a specific experiment. Microorganisms are often grown under laboratory conditions for various purposes. 3.

Selective media and differential media are two types of growth media. Selective media are the culture media designed for the growth of a selected organism while inhibiting the growth of other microorganisms.
Both selective and differential media are used to isolate and identify microorganisms. 1. Unlike selective media, differential media are not included with the chemical which suppresses or inhibits other microorganisms. While selective media do not typically identify bacteria down to the species level, they do help narrow down the search.

It indicates only if the target microorganism is present in the medium by showing a different growth pattern or visible change. 0000054278 00000 n 0000001092 00000 n 4. “MRSA on a selective choromogenic media plate” By Xishan01 – Own work (CC BY-SA 3.0) Commons Wikipedia 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. Selective media contain certain specific nutrients for growth of a particular microorganism and contain dyes or toxic substances to inhibit the growth of other microbes. For example, if a particular microorganism is resistant to a particular antibiotic such as tetracycline or ampicillin, that antibiotic can be added to the medium, prohibiting the growth of other microorganisms in that medium. Selective media can include dyes and other chemicals such as antibiotic types, specifically neomycin, that prevent the growth of some types of cells. For example, organisms that can utilize a given sugar are easily screened by making that sugar the only carbon source in the medium. “Culturing Media.” Boundless Microbiology, Available here. 0000000794 00000 n in Molecular and Applied Microbiology, and PhD in Applied Microbiology.

They are formulated to isolate and identify a particular type of microorganism. For example, if a microorganism is resistant to a certain antibiotic, such as ampicillin or tetracycline, then that antibiotic can be added to the medium in order to prevent other cells, …
Selective Media: Selective media are used to isolate a particular strain of microorganisms. 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. Compare the Difference Between Similar Terms. Differential media typically display some type color change in the presence of certain bacteria. 1.
