AYE broth
教:用于军团菌培养的AYE broth的配制,我现在使用的配方,总有些溶不开的东西,有哪位有经验的战友提供一下配方和配制方法。哈!果然是你!
不知道呀?
YE broth?是CYE broth吧?
CES buffered yeast extract (AYE) broth containing 10 g of N-(2-acetamido)-2-aminoethanesulfonic acid (ACES) buffer, 10 g of bovine serum albumin, 5 g of yeast extract, 0.4 g of l-cysteine-HCl, and 0.25 g of ferric pyrophosphate (all from Sigma, Deisenhofen, Germany) per liter of medium was used for in vitro cultivation of legionellae. All the ingredients were added to sterile distilled water, and the pH was adjusted with potassium hydroxide to 6.9. The AYE broth was filter sterilized and stored at 4°C.
是这个吗?
象这个配方就是BCYE-α去除活性炭,琼脂和α-酮戊二酸添加牛血清白蛋白的液体培养基.
临床上好象用的不是太多.

就是使用这个配方的, 0.4 g of l-cysteine-HCl, and 0.25 g of ferric pyrophosphate不完全溶于培养基,烦恼!回复 #6 巴斯德之徒 的帖子
于legionella 培养的液体培养基回复 #7 莲雾 的帖子
主要是焦磷酸铁不那么容易溶解,其实L-半胱氨酸盐酸盐是非常好溶解的.我想你用的可能是L-半胱氨酸,而不是它的盐酸盐,处理方法是用1mol/L盐酸先将它溶解,再用KOH调节PH至6左右后用0.22μm孔径的微孔滤膜过滤除菌,再加到已经高压灭菌的培养基中.
而焦磷酸铁要慢慢来,先加少许蒸馏水在乳钵中边碾磨溶解(必要时加热),再过滤除菌倒入灭菌好的培养基中.
