Abstract

Three strains of the blue-green algae Anabaena cylindrica, Anacystis nidulans and Nostoc muscorum are able to adjust the pH of culture medium from stress levels (pH 4-6) to levels favorable for growth (pH 7-10). Over a period of one week, these strains increased the buffer capacity of their media with time. The pH of maximum buffer capacity after one week was very close to the pK2 of phosphoric acid. Algae grown in a medium initially buffered with Na2CO3 shifted the pH of maximum buffer capacity from the pK of carbonic acid to that of phosphoric acid.
