Abstract:

Four media were used to study culturable fungal diversity in 10 gorgonian samples obtained from Weizhou Island, Guangxi Province. Fungi were further identified by colonial morphology observations and molecular biological analyses. Their anti-bacteria and anti-biofilm activities were determined by 96-well microplate assay. A total of 191 fungal strains were isolated from those gorgonians. All of the 191 fungi belonged to the phylum Ascomycota, and were distributed among six genera: Aspergillus, Penicillium, Alternaria, Cladosporium, Nigrospora, and Parengyodontium. Eleven fungal strains exhibited inhibitory effect against the three strains of pathogenic bacteria, which are Staphylococcus epidermidis ATCC12228, Streptococcus agalactiae ATCC51487, and Streptococcus iniae ATCC29178. The strains P. cinnamopurpureum GXIMD00518 and A. carneus GXIMD00519 also showed anti-MRSA biofilm activities. Gorgonians are rich resources of fungi that deserve further exploration.

Key words: gorgonian, marine derived fungus, biodiversity, anti-bacteria activity, biofilm
