*3.2. Fungal Material*

The fungal strain *Aspergillus terreus* RA2905 was isolated from a piece of fresh tissue from the inner part of the sea hare *Aplysia pulmonica*, collected from the Weizhou coral reefs in the South China Sea in April 2010. The fungus was identified as *Aspergillus terreus* according to its morphological traits and a molecular protocol by amplification and sequencing of the DNA sequences of the internal transcribed spacer (ITS) region of the ribosomal RNA (rRNA) gene by using ITS 1 and ITS 4. Its GenBank (NCBI) access number is MK611650. The phylogenetic tree of the ITS gene was constructed by the Neighbor-Joining method with the aid of MEGA 7 (Figure S1). The strain was deposited in the Key Laboratory of Marine Drugs, Ministry of Education of China, School of Medicine and Pharmacy, Ocean University of China, Qingdao, P. R. China.
