Microbes are prolific sources of bioactive molecules, however, access to microbial diversity has severely been hampered by the cultivability issue. Novel secondary metabolites from as-yet-unknown or atypical microorganisms from both temperate and extreme environments have realistic potential to lead to new drugs with tremendous benefit for human health. In this work, we used a novel approach that mimics the natural environment by using a Miniaturized Culture Chip (MCC) allowing the isolation of several bacterial strains from Antarctic shallow water sediments under near natural conditions. One of the strains, a Gram- negative Antarctic bacterium belonging to the genus Aequorivita was subjected to further analyses. The genome of the Aequorivita sp. was sequenced and a bioinformatics approach was applied to identify putative biosynthetic gene clusters. The organic extract of the Aequorivita sp. showed antimicrobial activity towards a panel of Multidrug Resistant (MDR) bacteria and antihelminthic activity against the nematode Caenorhabditis elegans. This is the first multi-approach study exploring the genomics and biotechnological potential of the genus Aequorivita and suggesting it as a promising candidate for pharmaceutical applications.
