The ability to photosynthesize is characteristic of all plants, which is the opposite process of cellular respiration, which all organisms use to create the energy needed for life. The surface of the ground is illuminated with ultraviolet radiation, inducing fluorescence in certain molecules. A standard and a blank also are processed so that the light output can be correlated to bacteria in the sample and system "noise" can be subtracted from the readings. Jacques Kelly, The Baltimore Sun People get their ideas from many different places. His method measures the amount of fluorescence over a forest and monitors the amount of photosynthesis in a selected area. This recognition resulted in his attendance at the University of Washington to complete an M.S.

Chappelle was later reassigned to the all-Black 92nd Infantry Division and served in Italy. The susceptibility of bacteria, particularly those derived from body fluids, to antimicrobial agents is determined in terms of an ATP index measured by culturing a bacterium in a growth medium, assaying the amount of ATP in a sample of the cultured bacterium by measuring the amount of luminescent light emitted when the bacterial ATP is reacted with a luciferase-luciferin mixture, subjecting the sample of the cultured bacterium to an antibiotic agent and assaying the amount of bacterial adenosine triphosphate after treatment with the antibiotic by measuring the luminescent light resulting from the reaction, whereby the ATP index is determined from the values obtained from the assay procedures. During the Space Race, Chappelle worked for NASA, where, among other accomplishments, he developed the ATP fluorescent assay, which could be used to detect microbial life in the soil on Mars.
