Abstract
Why the Hydrophobic Grid Membrane Filter (HGMF)?
The HGMF is a square membrane filter (60 x 60 mm, pore size 0.45 μm) printed with a black hydrophobic grid outlining 1600 (40 x 40) small squares. It was developed as a vehicle for electronic counting, and for this purpose it combines desirable features from plate and most probable number (MPN) counts. Some of its unusual properties result from the confining of colony growths to the grid cell in which they originated; a typical appearance after incubation is of a grid carrying randomly distributed square “colonies”.
