*3.2. Fungal Material*

The endophytic DY180635 was isolated from a sample of crab (*Chiromantes haematocheir*), which was collected from the intertidal zone of Zhoushan, Zhejiang, China, in June 2018. It was incubated on a potato dextrose agar (PDA) plate at 28 ◦C. The strain DY180635 was identified using ITS rDNA sequence analysis by RuiDi (Shanghai, China) and its DNA sequence using BLAST was compared to the GenBank data. The result of BLAST searching was closest to that of *Aspergillus versicolor* NRRL 238 (GenBank accession number NG\_067623) with 99% sequence identity. The nucleotide sequences of the ITS gene (accession number MT361076) of *A*. *versicolor* DY180635 were deposited in GenBank. A reference culture is stored in State Key Laboratory of Bioreactor Engineering laboratory of Shanghai at −80 ◦C.
