Abstract
An optimum medium for culturing Melosira italica (subsp. subartica) is described. The optimum concentration of humic acid for growth of this species in culture was found to be 46 µg/ml.
Tolerance to cupric ions also increased by addition of humic acid. Cultures tended to maintain a pH of about 6.0. Some ecological implications are discussed.
