Screening of antibacterial and antioxidant activities of marine fungi isolated from the North Sea of Vietnam

Marine fungi are recognized as a rich source of pharmacologically active secondary metabolites, different from terrestrial fungi. This study aimed to assess the antimicrobial and antioxidant activities 61 marine fungal strains isolated 34 samples collected in research journey Akademik Oparin vessel North Sea Vietnam 2021. Of these, 23 were sponges, 21 seaweeds, 15 sediments, only 2 seawater. The screening results showed that 75.4% (n = 46) exhibited inhibitory activity against at least one test microorganism. antioxidative properties indicated capacity for free DPPH (2,2-diphenyl-1-picrylhydrazyl) ABTS (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging crude extracts with 32.7% 20) 93.4% 57), respectively. Six isolates potent antibiotic identified belonging phylum Ascomycota affiliated five genera. Our findings these could be impressive sources multi-functional bioactive compounds may find applications pharmaceutical industry.
