Abstract

Seven isolates of Porphyridium from 2 species were compared. P. cruentum Naeg. isolates were similar in size and pigmentation; differences were observed among the P. aerugineum Geit. isolates. Differences were detected among isolates in reproduction, rate of movement, growth rate, and sensitivity to CuSO4 and crystal violet. No isolate grew heterotropically; however, growth differences were apparent on various carbon sources.
