Minutocellus polymorphus: A new marine diatom for use in algal toxicity tests

摘要

AbstractThe marine diatomMinutocellus polymorphusis suited for use as a test species in algal toxicity tests. Its responses to 19 toxicants in a modification of Aquil, a chemically defined phytoplankton culture medium, compared favorably with those ofSkeletonema costatum, a common test species.M. polymorphusgrows rapidly, allowing a test duration of 48 h and thus minimizing complications due to toxicant degradation, volatilization and adsorption to test vessel walls. These and other characteristics indicate thatM. polymorphusis an ideal standard organism for algal toxicity tests.
