differential media

(noun)

Differential media or indicator media distinguish one microorganism type from another growing on the same media.

Examples of differential media in the following topics:

  • Selective and Differential Media

    • Selective media allows for the growth of specific organisms, while differential media is used to distinguish one organism from another.
    • Two types of media with similar implying names but very different functions, referred to as selective and differential media, are defined as follows.
    • Differential media or indicator media distinguish one microorganism type from another growing on the same media.
    • Examples of differential media include:
    • MacConkey (MCK), which is differential for lactose fermentationmannitol salt agar (MSA), which is differential for mannitol fermentation.

  • Detecting Acid and Gas Production

    • Culture media can be used to differentiate between different kinds of bacteria by detecting acid or gas production.
    • Differential media, also known as indicator media, distinguish one microorganism type from another growing on the same media.
    • Differential media are used for the detection of microorganisms and by molecular biologists to detect recombinant strains of bacteria.
    • When cultured on an EMB (eosin methylene blue) plate, a positive result for E. coli is metallic green colonies on a dark purple media.
    • This raises the pH of the medium, allowing the O157:H7 strain to be differentiated from other E. coli strains through the action of the pH indicator in the medium.

  • Culture Media

    • Culture media is the food used to grow and control microbes.
    • These are the most common growth media, although specialized media are sometimes required for microorganism and cell culture growth.
    • This is an important distinction between growth media types.
    • Undefined media are sometimes chosen based on price and sometimes by necessity - some microorganisms have never been cultured on defined media.
    • Differential media - Also known as indicator media, are used to distinguish one microorganism type from another growing on the same media.

  • Complex and Synthetic Media

    • In defined media all the chemical compounds are known, while undefined media has partially unknown chemical constituents.
    • There are many types of culture media, which is food that microbes can live on.
    • Two major sub types of media are complex and synthetic medias, known as undefined and defined media.
    • Undefined media are sometimes chosen based on price and sometimes by necessity - some microorganisms have never been cultured on defined media.A defined medium (also known as chemically defined medium or synthetic medium) is a medium in which all the chemicals used are known, no yeast, animal, or plant tissue is present.
    • The term 'chemically defined media' is often misused in the literature to refer to serum albumin-containing media.

  • Enrichment and Isolation

    • The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are required for some microorganisms.
    • An important distinction between growth media types is that of defined versus undefined media.
    • Differential/indicator media distinguish one microorganism type from another growing on the same media.
    • The agar triple-sugar iron (TSI) is one of the culture media used for the differentiation of most enterobacteria.
    • The agar triple-sugar iron is one of the culture media used for the differentiation of most enterobacteria.

  • Promotion Objectives

    • Promotion is to present information to consumers to increase demand and to differentiate a product.
    • Many companies use different techniques to promote their products through a vast array of communication media.
    • Some of the most popular forms of online social media are Facebook, Twitter, and MySpace.
    • These are to present information to consumers as well as others, to increase demand, and to differentiate a product.
    • There are different ways to promote a product in different media.

  • Mobile Consumer Behavior

    • Social media applications used on mobile devices are called mobile social media.
    • In comparison to traditional social media accessed on computers, mobile social media display a higher location- and time-sensitivity.
    • One can differentiate between four types of mobile social media applications, depending on whether the message takes account of the specific location of the user (location-sensitivity) and whether it is received and processed by the user instantaneously or with a time delay (time-sensitivity).
    • Since these social media applications can be used on mobile devices, they are a good target for social media marketing.
    • Describe the four types of mobile social media applications and how they are used in social media marketing

  • Promotional Methods

    • B2B marketers use industry or trade publications, trade shows, private events, and social media to generate awareness about their products and services.
    • These publications are also placed in industry and trade media to produce favorable publicity.
    • If done strategically, media placement enforces messaging behind specific marketing activities across multiple communication channels.
    • Social media is fast becoming a promotional tool used to position B2B brands in the digital sphere.
    • Differentiate between the promotional methods and tools used in B2B versus B2C marketing

  • Careers in Marketing

    • Regardless of their role or function, marketers must present information to target audiences; increase consumer and customer demand; and differentiate products against market competition.
    • Today, field marketing may also include two-way communications such as requesting feedback about a sample, or inviting consumers to follow a brand on social media.
    • Advertisers handle a range of functions, including creative services, copywriting, account management, media planning, and media buying.
    • Media planners and buyers research the most appropriate online and offline platforms for advertisements.
    • For example, a CRM marketing analyst may focus on customer relationship management systems and analytics, while social media and engagement managers launch and oversee marketing campaigns across different social media platforms.

  • A Brief Description

    • There are different ways to promote a product in different areas of media.
    • Since the turn of the twenty-first century, many companies have been trying to utilize online social media for product promotion.
    • Some of the most popular forms of online social media are Facebook, Twitter, and Pinterest.
    • Within an online social media network, companies have the ability to advertise and promote their products to anyone, at any time, anywhere in the world.
