abstract：:The rate of adaptation of high CO(2) (5% v/v CO(2) in air)-grown Anabaena to a low level of CO(2) (0.05% v/v in air) was determined as a function of O(2) concentration. Exposure of cells to low (2.6%) O(2) concentration resulted in an extended lag in the adaptation to low CO(2) concentration. The rate of adaptation fo...
