Influence of Blue-Green Algae on the pH and Buffer Capacity of Culture Media

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 wi...
