Culture of Amoeba
Temporary cultures of amoeba can be easily prepared for laboratory study by hay infusion method , Dry and clean leaves grass wheat grains or banana peals are boiled in distilled water for about 15 minutes. The water is then filtered and allowed to stand open for 2to 3 days .This allows abundant bacterial growth in it ,Now some half rotten leaves are brought from a pond or ditch, washed ant put into the filtrate.
