SS agar is used as a selective medium for pathogenic enteric bacteria - usually used for Salmonella spp, but sometimes for Shigella spp (some of which may be inhibited). In addition, Proteus spp will form colourless colonies while any lactose fermenting organisms form pink colonies. Some H2S utilizing enterics will have black-centred colonies. Gram positive bacteria cannot grow on SS agar due to the high concentrations of brilliant green dye, sodium citrate, and bile salts.
The melting point of agar is useful because it determines the temperature at which agar solidifies and forms a gel. This property makes agar an important ingredient in microbiology labs for culturing bacteria and other microorganisms. By solidifying at a specific temperature, agar provides a solid medium for microbial growth and isolation.
Common solvents to dissolve agar include water, ethanol, and dimethyl sulfoxide (DMSO). It is important to use heat or agitation to aid in the dissolution process, depending on the type of agar used. Additionally, adjusting the pH of the solvent may also help in dissolving agar more effectively.
Approximately 2 teaspoons of agar agar powder is equivalent to 7 grams.
red algae Agar agar is a malay term meaning red algae. This algae which agar is extracted lives in the ocean around Malaysia
Yes, some marine bacteria and fungi have been identified to possess the capability to degrade agar agar. These microorganisms secrete enzymes such as agarases that breakdown agar into simpler sugars, which they can then use as a source of energy.

It is important to write on the "Agar side" of the plate because 1. you do not want your writing on the lid to interfere with your observations and 2. If you lose the lid you won't know what you streaked (what your wrote on the lid).Hope this helps!
Agar, or agar-agar, is not a grain, but rather an extract of seaweed. Agar translates to German as Agar-Agar Try whole- or health-food stores
Agar-agar
an extract of seaweed
It allows the agar to cool, if the agar is too hot it could kill the bacteria if you are pouring it right onto a sample, if you are pouring it into plates to use later it just makes it easier to pour as you will not be burning your hand off

No, agar agar does not contain collagen. Agar agar is a gelatinous substance derived from seaweed, while collagen is a protein found in the connective tissues of animals.

Agar is derived from seaweed and is often used in Japanese desserts
Agar agar can be used as a substitute for gelatin in recipes that call for it. Agar agar is a plant-based alternative that works similarly to gelatin in setting and thickening recipes.
