After the war, Chappelle attended Phoenix College and received an Associates Degree in electrical engineering, and then University of California Berkeley (funded by the GI Bill), where he received a Bachelors of Science in biology in 1950. However, his discovery is used today to find bacteria in urine, blood, drinking water, and food. 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. or bioluminescence.
