Gymnodinium catenatum paralytic Shellfish toxin production and photobiological ...
Lopes, Vanessa M.; Court, Mélanie; Seco, Martim Costa; Borges, Francisco O.; Vicente, Bernardo; Lage, Sandra; Braga, Ana Catarina; Duarte, BernardoMarine heatwaves (MHWs) have doubled in frequency since the 1980s and are projected to be exacerbated during this century. MHWs have been shown to trigger harmful algal blooms (HABs), with severe consequences to marine life and human populations. Within this context, this study aims to understand, for the first time, how MHWs impact key biological and toxicological parameters of the paralytic shellfish toxin (P...
Toxin profile of two Gymnodinium catenatum strains from Iberian Coastal Waters
Leal, Joana F.; Bombo, Gabriel; Pereira, Hugo; Vicente, Bernardo; Amorim, Ana; Cristiano, Maria L. S.Gymnodinium catenatum has been the main species responsible for paralytic shellfish poisoning events along the Portuguese coast (Iberian Peninsula), causing bans on bivalve harvesting that result in huge economic losses. This work presents the characterization of two novel isolates of G. catenatum regarding their growth and toxin profiles. Laboratory growth experiments revealed that, although low growth rates w...
Coccolithophores as potential marine resource for sustainable aquaculture
Vicente, Bernardo; Santos, Tamára; São João, Ricardo; Rodrigues, Luísa; Pereira, Hugo; Varela, João; Tenreiro, AnaCoccolithus braarudii (holococcolith) and Emiliana huxleyi (heterococcolith) were isolated from Portuguese coastal waters and domesticated under laboratory conditions with the objective of providing strains with high potential for the production of high value products for aquaculture and biotechnology. The growth patterns and photophysiology of the two species were investigated under controlled conditions, (19±...
