Patent ID: 8652799

Claim:
A method of detecting the presence of bioactive molecules in a fluid sample, comprising activating a microorganism selected from the group consisting of a monocellular algae and a cyanobacteria under ambient light; contacting a solution of the activated microorganism with the fluid sample so as to obtain a formulation having a microorganism concentration of 200,000-1×10 7 cells/mL of formulation; incubating the formulation for 10 to 120 minutes at a pH of 7 to 12 and a temperature between 18 and 35° C. under ambient light followed by incubating the formulation for 5 to 120 minutes at a pH of 7 to 12 and a temperature between 18 and 35° C. under green light or darkness; and measuring the fluorescence emitted by the formulation, whereby a fluorescence emitted in the sample that is lower than that in a control sample is an indication that the sample contains a bioactive molecule.
