Title
Diversity, ecological role and potential biotechnological applications of marine fungi associated to the seagrass Posidonia oceanica
Abstract

The marine environment is characterized by high salinity and exerts a strong selective pressure on the biota, favouring the development of halo-tolerant microorganisms. Part of this microbial diversity is made up of fungi, important organisms from ecological and biotechnological points of view. In this study, for the first time, the qualitative and quantitative composition of the mycoflora associated to leaves, rhizomes, roots and matte of the seagrass Posidonia oceanica was estimated. A total of 88 fungal taxa, mainly belonging to Ascomycota, were identified by morphological and molecular methods. The most represented genera were Penicillium, Cladosporium and Acremonium. Most of the species (70) were selectively associated with one district; only two species (Penicillium chrysogenum var. chrysogenum and P. janczewskii) were isolated from all the districts. Moreover the capability to produce laccases, peroxidases and tannases by 107 fungal isolated by the different districts of P. oceanica was carried out. These results show that the mycoflora associated to P. oceanica is very rich and characterized by fungi able to produce ligninolytic enzymes and tannases useful to degrade and detoxify lignocellulose residues in presence of high salt concentrations. These fungi, hence, may play important ecological roles in marine environments but can also be very useful in different biotechnological areas.

► The mycoflora of Posidonia oceanica is very rich and district specific. ► Most of the isolated species are selectively associated with one district. ► Many of the screened fungi resulted laccase, peroxidase and tannase producers. ► Marine Ascomycetes attack the lignocellulose residues present in the sea. ► Marine Ascomycetes produce extremozymes active at high salt concentrations.
