Few studies have addressed the diversity of cultivable fungi from marine sediments, especially those from Antarctica. In the present study, we evaluated the presence and distribution of cultivable fungi in marine core sediments obtained from 100, 500, 700 and 1,100 m below the Antarctic Ocean surface. Fifty-two fungal isolates were identified as Penicillium solitum by their physiological and morphological characteristics, and the identity of 12 representative isolates was further confirmed by sequencing of the ITS1-5.8S-ITS2 and b-tubulin genes. P. solitum displayed high sequence similarity to Penicillium taxa that have been described from other marine habitats. Conidial germination of P. solitum occurred at low temperatures and high salinities. In addition, P. solitum displayed extracellular amylasic and esterasic activities. The isolation of P. solitum from marine sediments in Antarctica and its survival at low temperatures and high salt concentrationssuggest that it is adapted to the cold and halophilic environment of the Antarctic oceans. Because P. Solitum produces extracellular enzymes, it is an interesting eukaryotic model for the study of structure?function relationships during enzymatic biocatalysis and biotransformation under extreme conditions. Marine sediments from Antarctica may represent a unique source for obtaining extremophilic fungi. New studies using different culture media, temperatures ranges and pressure conditions as well as metagenomic techniques can assist in understanding the extremophilic fungal communities in marine sediments across the Antarctic Ocean.
