Not more than 22% after drying at 105° until the difference between two weighings is less than 1 mg (about 5h). Unground agar should be cut into pieces from 2 to 5 mm 2 before drying. Total ash: Not more than 6.5% on the dried basis: Acid-insoluble ash: Not more than 0.5% on the dried basis: Foreign insoluble matter: Not more than 1% See growth media is used in the following forms: agar plates, agar slants and agar deeps. Melted agar is poured into a test tube and then allowed to solidify vertically for an agar deep, or at an angle for an agar slant. Agar plates are made by pouring melted agar into a petri dish. (Petersen, 2016) Because of the relatively small tube opening Abstract. Agar vs Carrageenan, both food gums are extracts from seaweed, but they have many differences. Carrageenan is soluble in water at about 80°C, forming a viscous, transparent, or slightly milky, easily flowable solution. Whereas agar does not dissolve into a solution below 85°C, it can only form a gel when the heated solution is Agar is used as a vegetarian substitute for gelatin in many food products. Agar is often used in microbiology to study the growth of microorganisms. Some types of agar are used in the production of cosmetics and personal care products. Agar is a popular ingredient in Asian cuisine, often used to make soups and stews.

Comparative analysis showed that alkali-treated agar of G. edulis gave the highest agar yield (82.56 %) whereas the highest gel strength was obtained from native agar of G. salicornia (430 ± 17.
Procedure. Preparing 5% agar solution (see Recipes). Production of the bottom layer of agar. Add 9 ml complete medium (37 °C) to 1 ml 5% agar solution (50 °C) and mix thoroughly. Pipette 0.8 ml mixture to each well of 12-well plate and allow it to solidify for 30 min at room temperature. Preparation of cell suspension.

In December 2000, we published a letter (PubMed PMID: 11198009) concerning the isolation of M. tuberculosis on both blood and chocolate agar media from a synovial fluid sample following prolonged incubation ( 5 ). In recent years, we have been routinely recovering M. tuberculosis in our laboratory from blood samples that have been cultured

0. Chocolate Agar, also known as Hektoen Enteric Agar (HE) is a type of culture medium used for the isolation and cultivation of gram-negative enteric bacteria, particularly Salmonella and Shigella species. The medium is made by adding blood, typically sheep or horse blood, to a base agar medium, which provides a source of nutrients for the
