What is Difco Bacto Agar?
Bacto ™ Agar is a solidifying agent in which extraneous matter, pigmented portions and salts have been reduced to a minimum. Bacto Agar is used in preparing microbiological culture media.
What is bacteriological agar?
Bacteriological agar is a colloidal substance and a cell wall component, obtained from Rhodoyceae (marine algae) and Gelidium sp. Agarose combined with agaropectin forms this polysaccharide. It is also called as agar-agar and is a polymer of galactoside. This agar is soluble in boiling water but not in cold water.
What is Bacto?
Bacto Peptone is an enzymatic digest of animal protein. Bacto Peptone contains nitrogen in a form that is readily available for bacterial growth. Bacto Peptone has a high peptone and amino acid content, with only a negligible quantity of proteoses and more complex nitrogenous constituents.
What is noble agar?
Noble agar, also known as agar or agar-agar, is a gelling hydrocolloid extracted from sea weeds such as Gelidium and Gracilaria. Noble agar is majorly used as both human and animal food supplement. In addition, it is also used in industries for the preparation of solid microbiological media.
Why Bacto agar is added in culture media?
Bacto™ Agar is a solidifying agent in which extraneous matter, pigmented portions and salts have been reduced to a minimum. Bacto Agar is used in preparing microbiological culture media. It is routinely used as a solidifying agent in microbiological media.
How do you use Bacto Agar?
Dissolve 15 g of Bacto agar in 1.0 L of LB medium and sterilize by autoclaving. Cool to 50°C in a temperature-controlled water bath. Add 0.50 mL of 100 mg/mL ampicillin. Pour into plates.
What is the function of bacteriological agar?
Blood agar, such as Columbia blood agar, is a highly nutritious general-purpose agar. Blood Agar is a general-purpose enriched medium often used to grow fastidious organisms and to differentiate bacteria based on their hemolytic properties. This medium is used for some microbiological identification tests.
What is the function of agar?
Agar is commonly used in the laboratory to help feed and grow bacteria and other microorganisms. It acts as a culture that provides nutrients and a place for these items to grow, but since it is indigestible to the microorganisms, they cannot eat and destroy it.
What is Bacto agar used for?
Bacto™ Agar is a solidifying agent in which extraneous matter, pigmented portions and salts have been reduced to a minimum. Bacto Agar is used in preparing microbiological culture media. Agar, Grade A is a high-grade agar, specially processed for microbiological purposes.
Is Bacto Peptone the same as Peptone?
All Answers (1) Yes, you can if the Peptone you have is for preparation of microbiological culture media. “Bacto” Peptone is just a commercial name for such Peptone (Bacto is the brand company commercialized by BD owning Difco).
Why are peptones used in media preparation?
Peptone is used in culture media to mainly supply nitrogen. Most organisms are capable of utilizing the amino acids and other simpler nitrogenous compounds present in peptone. Certain bacteria require the addition of other nutrients, such as serum, blood, etc. to the culture medium upon which they are to be propagated.
How much Bacto Agar do I add?

Which is the best source of Difco agar?
Gelidium is the preferred source for Difco agars. Impurities, debris, minerals and pigment are reduced to specified levels during manufacture. Agar was first suggested for microbiological purposes in 1881 by Fannie Hesse.1, 2By the early 1900s, agar became the gelling agent of choice over gelatin because agar remains firm at growth temperatures
