    Description: This study aimed at isolating microorganisms associated with the mesopelagic jellyfish Periphylla periphylla collected in Irminger Sea at a depth of 325 m in July 2020. Three different solid cultivation media; Hastings, Marine agar and Wickerham media were used for the isolation of the associated microorganisms. A total of 43 bacteria were isolated from the inner and outer surfaces of the umbrella of P. periphylla, but unfortunately, no fungal strain was isolated. Isolates were further identified by Sanger sequencing of the 16S rRNA gene, and based on phylogenetic distinctiveness (differences in closest relative species according to the nucleotide BLAST), 16 bacteria belonging to 8 different genera were selected and subjected to an OSMAC cultivation regime approach using liquid and solid marine broth and glucose– yeast–malt media. After 7 days of cultivation, cultures were extracted with ethyl acetate and assessed for antimicrobial activity against fish and human pathogens. Based on antimicrobial activity assessment, four most bioactive strains; Polaribacter sp. SU124, Shewanella sp. SU126, Psychrobacter sp. SU143 and Psychrobacter sp. SU137, were prioritized for a comparative and untargeted metabolomics analysis using feature-based molecular networking. These findings highlight the biotechnological potential of P. periphylla-associated microbiota.

    Description: Identification of 16 selected bacteria associated to the umbrella of Periphylla periphylla collected in the Irminger Sea based on sequencing of the 16S ribosomal RNA gene and BLAST against the NCBI nucleotide database. The table displays the first 3 hits from two blastn searches, one against all database entries and the second against type strains only. Nucleotide identities (%) with database hits and NCBI accession numbers assigned to the isolated bacteria are also displayed. Colonies were cultured either in marine broth, Hastings medium or Wickerham medium for comparison.

    Description: Putative annotation of metabolites produced by the Psychrobacter sp. SU143, Psychrobacter sp. SU137, Shewanella sp. SU126 and Polaribacter sp. SU124 in the liquid and solid regime of Marine Broth and Glucose-Yeast-Malt media. Annotation was based on the m/z [M+H]+ or other adducts, retention time, predicted molecular formula, fragmentation pattern and source of the hit. The source of the ion is indicated by the area under a peak (peak area count). Confidence level of annotation are given based on the reporting standards proposed by Sumner, et al. 2007, i.e. identified compound, is putative annotation without reference standards, is putative characterized compound class, and is unknown compound. The mass spectrometry data used for the molecular networking analysis were deposited in the MassIVE Public GNPS database under the accession number MSV000091067.
