取陈旧稻草垫子的稻草,剪成0.5—1寸长,放在150毫升的小烧瓶内,加5克葡萄糖,再放100毫升凉开水(经煮沸10—15分钟后晾凉的),用纱布盖好,放在恒温箱内培养,在23℃左右,经5—7天就可培养出草履虫。此时将表面白膜移开,用肉眼即可观察到草履虫的白色小点。培养液中加葡萄糖的作用是使培养液中增加营养,有利于细菌和其他微生物的繁殖,为草履虫提供了充足的饵料。同样道理,在培养液中加入维生素,草履虫会生长得更好、更大。
Take the straw of the old straw mat, cut into 0.5-1 inch long, placed in a 150 ml small flask, add 5 grams of glucose, then add 100 ml of cold water (boiled 10-15 minutes after boil cool), gauze Cover well and incubate in a thermostat. At about 23 ℃, Paramecium can be cultivated after 5-7 days. At this point the surface of the white membrane removed, with the naked eye can be observed paramecium white dots. The role of glucose in culture broth is to increase nutrition in culture solution, which is beneficial to the propagation of bacteria and other microorganisms and provides adequate feed for Paramecium. By the same token, paramecium grows better and more in vitamins.
