ABSTRACT:
Highly porous, beads are comprised of a polymer and a second compound mixed into it. The second compound, an amendment, is either a nutrient or a compound having high affinity to one or more nutrients. A plurality of these beads may be exposed to an aqueous environment, usually a body of water. Bacteria and other microorganisms rapidly enter and remain within the nutrient filled interior space of the beads. Any of a number of various detection methods may then be used to characterize, detect and/or identify the microorganisms.
