Use membrane filters of the ideal material with a pore measurement of 0.45 µm or fewer. Filters about fifty mm throughout are proposed, but other measurements may be applied. Sterilize the filters, filtration apparatus, media, together with other equipment utilised. Normally, evaluate two test fluids of ten ml Each and every; pass Each and every sample via a different filter. Dilute the pretreated test fluid if the bacteria focus is superior, to ensure ten a hundred colonies can establish for every filter. Just after filtration, wash Each and every filter 3 times or more with an suitable liquid such as phosphate buffer, sodium chloride- peptone buffer, or fluid medium.
