Effect of Deuterium on Starving Bacteria


THE presence of high concentrations of deuterium oxide in growth media has been shown to be toxic to bacteria1. The effects are characterized by long lag periods before growth occurs and subsequent slow growth with the production of distorted forms. However, experiments designed to study the effect of deuterium oxide on bacteria starving in buffer solutions showed that deuterium oxide was not toxic under these conditions and that the longevity of the bacteria was increased.
