Characterizing the Potential of the Non-Conventional Yeast UTAD17 in Winemaking.

Non- yeasts have received increased attention by researchers and winemakers, due to their particular contributions to the characteristics of wine. In this group, is one of the less studied species. In the present study, a native strain, UTAD17 isolated from the Douro wine region was characterized for relevant oenological traits.

Reevaluation of production of paralytic shellfish toxin by bacteria associated with dinoflagellates of the Portuguese coast.

Paralytic shellfish toxins (PSTs) are potent neurotoxins produced by certain dinoflagellate and cyanobacterial species. The autonomous production of PSTs by bacteria remains controversial. In this study, PST production by two bacterial strains, isolated previously from toxic dinoflagellates, was evaluated using biological and analytical methods.
