Research Abstract

This study revealed that unknown fungal communities exist in deep subsurface ecosystems with unexpected diversity and novelty. More than 100 fungal species were isolated from deep-sea sediments, deep-sea sponges, shellfishes, sea plants lying on deep-sea floor and other organisms collected in deep-sea environments. All species were identified and screened for antimicrobial agents. As some isolates appear to produce antimicrobial agents, this has great potential for future application research.
