Comparative growth and toxin profile of cultured Ostreopsis ovata from the Tyrrhenian and Adriatic Seas

Potentiality of benthic dinoflagellate cultures and screening of their bioactivities in Jeju Island, Korea

“…In addition, growth rate of 0.15 to 0.25 divisions day -1 is similar to growth rate of 0.22 divisions day -1 mentioned by Nascimento et al (2012). However, it was lower than 0.53 divisions day -1 (Guerrini et al, 2010), 1.07 divisions day -1 (Granéli et al, 2011) and 1.03 divisions day -1 (Yamaguchi et al, 2012). Dason and Colman (2004) ) for 24 h, the NO levels in the medium was measured.…”

Morphological and genetic characterization of benthic dinoflagellates of the generaCoolia,OstreopsisandProrocentrumfrom the south-eastern Bay of Biscay

“…The toxicity of both species is well documented (Murakami et al, 1982;Rhodes et al, 2000;Bravo et al, 2001;Foden et al, 2005;Ciminiello et al, 2006Ciminiello et al, , 2008Mohammad-Noor et al, 2006;Aligizaki et al, 2008aAligizaki et al, , 2009Vale et al, 2009). Differences in the toxic character of a species can be due to the presence of multiple cryptic species within a morphospecies, as reported by Richlen et al (2008) for Gambierdiscus, or because the same species of microalgae may present varying toxicity depending on physiological status, environmental conditions or even between populations in different areas (Guerrini et al, 2009). Our C. monotis strains are not toxic, in agreement with the observations on other European Atlantic and Mediterranean strains (Penna et al, 2005).…”

Warm Seawater Microalgae: Growth and Toxic Profile of Ostreopsis Spp. from European Coasts

“…300 cells/ml was always used as initial inoculum and the profile and conditions of growth for each strain were previously established. In these cultures the beginning of the stationary phase of growth was reached 15-18 days after inoculation [25]. The dinoflagellates were kept under these conditions for 30 days, then the whole culture volume was carefully filtered, 20 µm mesh, and the residue obtained was weight.…”

“…Ostreopsis spp. grows better in calm, shallow, warm waters and it seems that high salinity concentration increases their development [25][26][27]. But it is not clear the importance of the salinity and nutrients in their blooms [26].…”
