Microbes are prolific sources of bioactive molecules; however, the cultivability issue has severely hampered access to microbial diversity. Novel secondary metabolites from as-yet-unknown or atypical microorganisms from extreme environments have realistic potential to lead to new drugs with benefits for human health. Here, we used a novel approach that mimics the natural environment by using a Miniaturized Culture Chip allowing the isolation of several bacterial strains from Antarctic shallow water sediments under near natural conditions. A Gram-negative Antarctic bacterium belonging to the genus Aequorivita was subjected to further analyses. The Aequorivita sp. genome was sequenced and a bioinformatic approach was applied to identify biosynthetic gene clusters. The extract of the Aequorivita sp. showed antimicrobial and anthelmintic activity towards Multidrug resistant bacteria and the nematode Caenorhabditis elegans . This is the first multi-approach study exploring the genomics and biotechnological potential of the genus Aequorivita that is a promising candidate for pharmaceutical applications.
