The characterization of autochthonousSaccharomyces cerevisiaestrains is an important step towards the conservation and employment of microbial biodiversity. The utilization of selected autochthonous yeast strains would be a powerful tool to enhance the organoleptic and sensory properties of typical regional wines. In fact, indigenous yeasts are better tailored to a particular must and because of this they are able to praise the peculiarities of the derived wine. The present study described the biodiversity of indigenousS. cerevisiaestrains isolated from natural must fermentations of an ancient and recently rediscovered Apulian grape cultivar, denoted as “Susumaniello.” The yeast strains denoted by the best oenological and technological features were identified and their fermentative performances were tested by either laboratory assay. Five yeast strains showed that they could be excellent candidates for the production of industrial starter cultures, since they dominated the fermentation process and produced wines characterized by peculiar oenological and organoleptic features.

Aims and methodThe effectiveness of official support provided following a disaster has not been fully evaluated. This study aimed to ascertain whether there was an association between perceived support shortly after the 2004 Indian Ocean tsunami and later mental health symptoms in those affected, and to explore the factors associated with this. A survey, semi-structured interviews and focus group were used to explore the experiences and perceptions of 116 individuals severely affected by the tsunami.ResultsAgency or official support was perceived as poor overall. Perceived ineffectiveness of support available within a few days after the tsunami was associated with increased symptoms of post-traumatic stress disorder 15–19 months later. The strongest themes that emerged from our study were that support provided in a humane manner was perceived as effective and that uncoordinated support, poor communication and limited accessibility to support and information were perceived as ineffective.Clinical implicationsImproved planning of coordinated, flexible, multi-agency responses to traumatic events before they occur is required.
