Abstract: | Summary The growth ofChlorella pyrenoidosa in a special medium based on the critical concentrations of nutrients for autotrophic growth has been shown to be stimulated more by chloride with the sodium salt than with the potassium salt, more by sulphate in the presence of sodium than in the presence of potassium, and to be inhibited by sodium dihydrogen phosphate and not by potassium dihydrogen phosphate. Furthermore, it has been found that calcium reversed the growth inhibition produced by sodium dihydrogen phosphate, and that strontium only partially substituted for calcium. |
