Abstract: | Conditions for proline uptake and utilization by Chlorella pyrenoidosa Chick are described. Proline is taken up by growing cultures during late log phase growth after depletion of glucose from the medium. However, proline uptake by stationary phase cultures requires the presence of glucose in the medium. The results are consistent with the interpretation that some carbohydrate is required for proline uptake but proline uptake is inhibited by the accumulation of intracellular carbohydrates. |
