Differbetween
The key difference between solid and liquid media is that solid media contain agar while liquid media do not contain agar. ... But, liquid media are used for various purposes such as propagation of a large number of organisms, fermentation studies, and various other tests.

What is a liquid media?
Liquid media are often mixed with agar and poured via a sterile media dispenser into Petri dishes to solidify. These agar plates provide a solid medium on which microbes may be cultured. ... Bacteria grown in liquid cultures often form colloidal suspensions.
What is the difference between Agar and broth media?
The only difference between broth and agar media is that broths do not contain an agar component. We use broth tubes primarily for specific assays, or (rarely) for bacteria that will not form colonies on a solid surface. ... Unlike preparation of agar plates, tubes are prepared with media already in the incubation vessel.
What is solid media in microbiology?
Solid medium contains agar at a concentration of 1.5-2.0% or some other, mostly inert solidifying agent. Solid medium has physical structure and allows bacteria to grow in physically informative or useful ways (e.g. as colonies or in streaks).
Why is liquid media used?
Liquid media are used for growth of pure batch cultures, while solidified media are used widely for the isolation of pure cultures, for estimating viable bacterial populations, and a variety of other purposes. The usual gelling agent for solid or semisolid medium is agar, a hydrocolloid derived from red algae.
What is an example of a liquid medium?
An example of a liquid medium in drawing is: pastel. silverpoint.
How do you make liquid media?
The basic steps for preparing liquid media suitable for anaerobes are as follows: 1) preparation of culture media, 2) purgation of oxygen from the media by bubbling with anoxic gas, 3) sterilization of the sealed vessels by autoclaving, and 4) addition of reducing agents.
Is nutrient agar solid or liquid?
The main difference between them is that nutrient agar contains a solidifying agent, agar powder that causes the medium to solidify in room temperature, whereas nutrient broth remains in liquid form. Example of nutrient agar in a petri dish.
What is the use of nutrient agar?
Nutrient agar is a general purpose medium supporting growth of a wide range of non-fastidious organisms. It typically contains (mass/volume): 0.5% Peptone - this provides organic nitrogen. 0.3% beef extract/yeast extract - the water-soluble content of these contribute vitamins, carbohydrates, nitrogen, and salts.
What is broth and agar?
Agar is solidified media while broth is liquid media. 2. Agar is used for the Isolation and preservation of bacterial culture while N. broth is used to prepare bacterial Culture for growth and cultivation for production.
Are slants solid media?
Solid growth media is used in the following forms: agar plates, agar slants, and agar deeps.
What are the examples of enrichment media?
Enrichment media allow the growth of a particular type of microorganism in the medium. The examples of enriched media are blood agar, chocolate agar, Loeffler's serum, etc. The examples of enrichment media are Selenite F broth, tetrathionate broth, alkaline peptone water (APW), etc.
What is selective agar?
Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms. ... Tellurite agar, therefore, is used to select for Gram-positive organisms, and nutrient agar supplemented with penicillin can be used to select for Gram- negative organisms.
