| 内容記述 | Noxious Chattonella species cause many red tides and fish kills. The detection of extracellular O2− produced by these algae will be critical for the development of a rapid toxicity-evaluation method; however, such a development has been prevented by the mismatch of the extracellular O2− detection level between field and laboratory experiments. The aim of this study was to identify impediments to detect extracellular O2− in laboratory experiments. Our results indicate that Mn and Co in the medium decreased the detection levels of extracellular O2− produced by Chattonella antiqua, and the effect by Mn was stronger than that by Co. IC50 of the radical-scavenging activity of Mn was 17.5 μM, and little activity was detected at 8.75 μM or less. Furthermore, the level of extracellular O2− production by C. antiqua in Mn-depleted medium varied greatly under various culture conditions; the extracellular O2− production level of C. antiqua was high under conditions similar to those under which blooms develop in the field. Therefore, Mn is a key scavenger of extracellular O2−, and amounts of Mn must be carefully considered whenever extracellular O2− production levels of phytoplankton cultured with other kinds of media are measured. | |||||
