설명

일반 설명

Middlebrook 7H10 Agar Base is recommended for isolation, cultivation and sensitivity testing of Mycobacterium tuberculosis. Middlebrook media consists of many inorganic salts, which help, in growth of Mycobacteria. Citric acid formed from sodium citrate helps in retaining inorganic cations in solution. Glycerol supplies carbon and energy. Middlebrook OADC Growth Supplement (M0678) contains oleic acid, bovine albumin, sodium chloride, dextrose and catalase. Oleic acid and other long chain fatty acids are essential for metabolism of Mycobacteria. Some free fatty acids are toxic to Mycobacteria, but albumin binds to those fatty acids and prevents toxic action on Mycobacteria. Dextrose serves as an energy source. Catalase neutralizes toxic peroxides. Malachite green partially inhibits other bacteria.

애플리케이션

Middlebrook 7H10 Agar Base is a selective media for isolation, cultivation and sensitivity testing of Mycobacterium tuberculosis. Mycobacteria grow most rapidly in broth media and hence primary isolation of bacterial species can be carried out. It is inexpensive, easy to prepare and can aid in early detection of acid-fast, Mycobacterium species by culture.

제조 메모

Suspend 19.47 g of Middlebrook 7H10 Agar Base in 900 ml of distilled water. Add 5 ml of glycerol (Cat. No. 49767). Boil to dissolve the medium completely. Distribute in 180 ml amounts in erlenmeyer flasks and sterilize by autoclaving at 15 lbs. pressure (121°C) for 10 minutes. Cool to 45°C and aseptically add 20 ml of Middlebrook OADC Growth Supplement (Cat. No. M0678). Mix well and pour into screw capped tubes.Note: Keep prepared medium in the dark before and after inoculation.
