MacConkey agar contains bile salts, lactose, peptone. crystal violet dye, and neutral red dye. The agar appears a medium pink with a copper undertone.
Lac+ bacteria is acid base color indicator that lowers the pH of the MacConkey agar. The MacConkey agar contains neutral red dye, lactose, peptone, and crystal violet dye.
red algae Agar agar is a malay term meaning red algae. This algae which agar is extracted lives in the ocean around Malaysia
Agar comes from Red Algae (primarily the Gracilaria genus).It mainly is produed from the red algae Gracilaria lichenoides.This algae is harvested along the western coast of the United States and in parts of Asia. To extract the agar the Algae is boiled, cooled, purified and then dried. The agar is then make into blocks, flakes, or granules.("Agar agar" is usually abbreviated as "agar".)

Violet Red Bile Agar is recommended for use in the microbiological analysis of milk and other dairy products and for use in the examination of water. Violet Red Bile Agar is a selective medium which detects the growth of lactose fermenting coliforms. Coliforms colonies lower the pH of the medium subsequently causing their colonies to look red (neutral red dye) and to precipitate the bile salts. Crystal violet and bile salts inhibit the growth of Gram positive microorganisms.
marine red algae
Red algae cell walls contain agar. while green algae cell walls contain cellulose Answer 2 Agar is a chemical obtained from walls of certain red marine algae .It is not Algae itself .
