<p>An improved method of determining a viable microbial cell count in a sample solution with an enhanced detection sensitivity is provided, comprising filtering the sample solution through a filtration membrane having hydrophobic properties to entrap microbes within hydrophobic barriers; applying thereto a fine spray of ATP extracting reagent to extract a luminescent ingredient from the microbes; applying thereto another fine spray of liquid luminescence-inducing reagent for the luminescent ingredient extracted to allow the ingredient to emit luminescence; and measuring the level of the luminescence, using a competent means for measuring the luinescence level. The microbes and the two types of reagents are locally concentrated due to the hydrophobic properties of the membrane and thus the sensitivity is greatly enhanced, permitting instant counting in the case of large microbes, and decreased culture time for smaller bacterial microbes.</p> |
