*3.2. Fungal Material*

The fungal strain *Epicoccum nigrum* SD-388 was isolated from the deep-sea sediment collected in the West Pacific (depth 4500 m) on March 2015. The fungus was identified using a molecular biological protocol by DNA amplification and sequencing of the ITS (internal transcript spacer) region. The sequence data for the fungus have been deposited in GenBank with the accession no. MN089646. Through the BLAST searching, the fungus was identified as *Epicoccum nigrum* according to the ITS region sequence, which is the same (100%) as that of *E. nigrum* (accession no. KU254609). The strain is preserved at the Key Laboratory of Experimental Marine Biology, Institute of Oceanology, Chinese Academy of Sciences (IOCAS).
