產品說明
Giolitti-Cantoni Broth Base(GC 增菌液基礎)是金黃色葡萄球菌最確數法與低菌量檢體的選擇性增菌液:氯化鋰與使用前加入的亞碲酸鉀抑制雜菌,甘露醇與丙酮酸鈉幫助受損的葡萄球菌復原,培養後變黑或產生黑色沉澱即為推定陽性,再劃線 Baird-Parker 平板確認。ISO 6888-3 指定使用,適合乳粉、嬰兒食品與加工後菌數偏低的檢體。基礎配方,亞碲酸鉀依方法添加。
原理
Giolitti-Cantoni Broth was described by Giolitti and Cantoni for the enrichment of staphylococci from foods.¹ Tryptone, meat extract, and yeast extract supply nitrogen, amino acids, vitamins, and growth factors. Mannitol, glycine, and sodium pyruvate stimulate the growth of Staphylococcus aureus; sodium pyruvate also degrades hydrogen peroxide and assists the recovery of sub-lethally injured cells. Lithium chloride and potassium tellurite inhibit Gram-negative bacteria and most Gram-positive organisms other than Staphylococcus aureus. Sealing the tubes with paraffin creates anaerobic conditions that suppress micrococci, while the facultatively anaerobic Staphylococcus aureus continues to grow. Staphylococcus aureus reduces tellurite to metallic tellurium, producing blackening of the medium, which is taken as a presumptive positive result. Blackened tubes are subcultured onto Baird-Parker Agar for confirmation.²
配製與使用
Suspend 54.2 g of powder in 1 L of purified water. Heat with continuous stirring and bring to the boil for 1 minute. Dispense into tubes. Sterilize by autoclaving at 121°C for 15 minutes. Cool and aseptically add sterile potassium tellurite solution to the concentration specified in the applicable method. After inoculation, seal each tube with a layer of sterile molten paraffin or agar. Test the finished medium for performance using stable, standard control cultures.
