產品說明
m-FC Agar(m-FC 糞便大腸桿菌群培養基)是濾膜法檢測水中糞便大腸桿菌群的培養基:以 44.5°C 的高溫培養搭配玫瑰紅酸與膽鹽選擇,糞便大腸桿菌群發酵乳糖使苯胺藍指示劑轉藍,長成藍色菌落。APHA 水質標準方法 9222D 指定使用,是河川、養殖用水、遊憩水域與廢水處理放流水監測的標準項目。含染劑,加熱溶解後不可高壓滅菌。
原理
m-FC Agar was developed by Geldreich and co-workers for the enumeration of fecal coliforms by membrane filtration without a preliminary enrichment step.¹ Tryptose, proteose peptone, and yeast extract supply nitrogen, amino acids, vitamins, and growth factors, and sodium chloride maintains the osmotic equilibrium. Lactose is the fermentable carbohydrate. Bile salts inhibit Gram-positive organisms, and rosolic acid suppresses the background growth of non-coliform bacteria. Membranes are incubated at 44.5°C, a temperature at which only thermotolerant (fecal) coliforms grow well. Fecal coliforms ferment lactose, and the acid produced reacts with aniline blue so that colonies appear in various shades of blue; non-fecal coliforms and other organisms form grey to cream-coloured colonies. Blue colonies are counted and the result is expressed as fecal coliforms per 100 mL of sample.²
配製與使用
Suspend 52.1 g of powder in 1 L of purified water containing 10 mL of a 1% solution of rosolic acid in 0.2 N sodium hydroxide. Heat with continuous stirring and bring to the boil for 1 minute. DO NOT AUTOCLAVE. Cool to 45-50°C and dispense into 50-60 mm Petri plates. Test the finished medium for performance using stable, standard control cultures.
