Emmett Chappelle Biography. Jan 1, 1942, Graudated for High School. Working with scientists at the Beltsville Agricultural Research Center, he advanced the development of LIF as a sensitive means of detecting plant stress. 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 sample is diluted with sterile, deionized water, then mixed with a luciferase-luciferin mixture and the resulting light output of the bioluminescent reaction is measured and correlated with bacteria present. Growth of the bacteria in the parts are determined, again by an ATP assay, to determine whether the unidentified bacteria in the sample are susceptible to the antibiotic or antibiotics under test. Additionally, he developed a method for determining vegetation health by using laser-induced fluorescence to measure the amount of photosynthesis occurring in crops, allowing scientists to detect plant stress, determine growth rates, water conditions, and harvest timing.
