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. In 2001 Chappelle retired from the NASA. 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. There, Chappelle made a discovery that has contributed to the knowledge of bacteria, cyanobacteria, and other single-celled organisms around the world.
