✦ Synopsis

The effect of pH on copper toxicity to two planktonic blue-green algae, Aphanizomenon gracile and Oscillatoria redekei, was investigated. Growth rates of the algae without copper treatment decrease with pH, Aphanizornenon is earlier and more affected than Oscillatoria. On the other hand, pH-lowering leads sooner to a toxicity enhancement in Oscillatoria. In the acid range, toxicity retardation occurs in Aphanizornenon. At pH 5.1, shortening of the interval between copper toxicity and copper stimulus is characteristic for both species.

## Abstract The effect of 21 amino acids was studied on glycogen accumulation during sporulation in the blue‐green alga __Anabaena sp.__ All the amino acids enhanced the initial level of glycogen on the 4th day. The maximum amount of glycogen, on the 20th day, was noticed from l‐methionine, l‐tyros
