RESUMO

The mutant E1 of Anacystis nidulans R2 requires high CO2 concentration for growth but was able to adapt to low CO2 concentration. This was exhibited by the increased ability to accumulate inorganic carbon within the cells and the large increase in the amount of a 42-kilodalton polypeptide located in the cytoplasmic membrane. The adaptation occurred in E1 cells at an extracellular CO2 concentration as high as 0.3%, which was 8 times the concentration for maximal adaptation in R2 cells. The ability of E1 cells to exhibit low CO2 characteristics at a higher CO2 concentration was attributed to lower intracellular CO2 concentration.
