Agar is commonly used in microbiology laboratories as a solidifying agent for culture media, allowing for the growth and isolation of microorganisms. It is also used in the food industry as a thickening agent in products like desserts and jelly. Additionally, agar is used in science education for classroom experiments and demonstrations.
agar is used for two different things ... the 1st thing is that agar is used for cooking and the 2nd reason is that agar is used to make agar jelly so if you put the agar jelly in a jar (with a lid!) you can wipe your hand on the jelly then put the lid on top then later on you will see microbes form on the agar. thank you for reading x
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.
The common ratio for mixing agar agar powder with water is 1 tablespoon of agar powder to 1 cup of water. This ratio may vary depending on the specific recipe or intended use.
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.
Prepare a Vogel-Johnson agar base according to the recipe. Autoclave the agar base and cool it to 45-50°C. Add Vogel-Johnson selective supplement to the agar base. Pour the agar mixture into plates and allow it to solidify before use.
Himedia ready-to-use nutrient agar plates come already prepared and ready for use, while plates prepared from dehydrated media require you to rehydrate and prepare the agar medium before use. Ready-to-use plates save time and effort, while dehydrated media offer more flexibility in adjusting the agar concentration or adding selective agents as needed.

MacConkey agar is yellow (due to the lactose in the agar). When an organism consumes the lactose, the agar turns purple. Purple indicates a positive test. If the organism doesn't use the agar, the agar stays yellow.
Why is it impotant to use dry and hard agar for streaking
Phage can move easily in soft agar,it can bind with another bacteria after lysis
Use 1/3 tablespoon of agar. Don't forget to heat it.

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
Agar is commonly used in microbiology laboratories as a solidifying agent for growing bacteria and other microorganisms. It can also be used in food production, specifically in the production of desserts like jellies and custards.
In our lab we use LB agar, LB broth, and 2XYT broth.
