Abstract
Acti-dione inhibits the growth of Chlorophyceae, Xanthophyceae, and Bacillariophyceae at concentrations of 50 p.p.m. or less, but much higher concentrations have no inhibiting effect on the development of Myxophyceae. At concentrations of 50 to 100 p.p.m., it has been successfully employed in the isolation of unialgal cultures of two species of Myxophyceae. Haematococcus lacustris, a species of Chlorophyceae, has the lowest tolerance to Acti-dione of any microorganism yet found. Acti-dione interferes with cell division of this species at very low concentrations (0.016 to 0.032 p.p.m.), but much higher concentrations are required to inhibit motility. The effect of Acti-dione may be algistatic or algicidal depending upon the concentration used, the duration of the exposure, the species concerned, and the cell density.Keywords
