Culture of thermophilic algae and other microorganisms in heavy water
- eds.
From first international conference on stable isotopes in chemistry, biology, and medicine; Argonne, Illinois, USA (9 May 1973). In proceedings of the first international conference on stable isotopes in chemistry, biology, and medicine. Two specie s of thermophilic algae, Chlorella pyrenoidosa and Synechococcus lividus, were cultured in heavy water. Analysis of the doubling times and growth curves for the algae in heavy water indicate a consistent deuterium isotope effect on the growth rate of the algae in heawy water as compared to H/sub 2/O. The effect is particularly noted in light-saturated cultures. Light-limited cultures show a smaller decrease in growth rate and may be useful in deriving fully deuterated products. (ERB)
