持续光照下光强对北极海域芬迪亚历山大藻生长及产毒的影响
INFLUENCE OF IRRADIATION ON THE PARALYTIC SHELLFISH TOXIN CONTENT AND PROFILES OF ALEXANDRIUM TAMARENSE ISOLATED FROM THE ARCTIC WATERS
摘要
Abstract
A comparative analysis of the physiology and toxin composition was performed on a suite of clonal cultures of the potentially toxic dinoflagellate Alexandrium tamarense. These were established from resting cysts or ve-getative cells isolated from sediment or the water taken from the coasts of Greenland, Iceland, Chukchi Sea and Gulf of Maine. Maximum growths were observed between 38 μmol?m–2?s–1and 91 μmol·m–2·s–1. No dcGTX2 was detected in all 12 isolates, toxin content significant variation was observed. In general, toxin contents and toxicity were generally highest at higher irradiation. This may indicate that the genetically de-termined toxin profiles in A. tamarense species are more complex than previously appreciated.关键词
