There have been no studies in which a significant number of isozymes have been investigated during a synchronous growth cycle of any organism. The present study was designed to obtain information on the fluctuations of a broad spectrum of enzymes during a synchronous growth cycle of Chlorella pyrenoidosa. Of the thirty‐two enzymic activities investigated, seventeen could be localized on starch gels from a high temperature strain of Chlorella pyrenoidosa. Nine of these activities were found to possess more than one band of activity by starch gel electrophoresis. Seven of these activities were localized on starch gels throughout a synchronous growth cycle of C. pyrenoidosa grown in continuous light. Assay techniques are described. The fluctuations in enzyme activity are discussed with relation to concurrent metabolic and cytological changes during cell maturation in C. pyrenoidosa.
