Biodiversity and Biological Interactions of Actinobacteria Associated with Deep Sea and Intertidal Marine Invertebrates.

ABSTRACT: Studying marine Actinobacteria across ecological niches is essential for discovering novel natural products and understanding microbial interactions. In this study, we investigated the diversity of Actinobacteria associated with five Arctic marine invertebrates using both selective culture-based techniques and culture-independent methods. Additionally, we investigated bacteria-bacteria interactions in an advanced high-throughput co-cultivation assay. We isolated 25 Actinobacteria and classified them into 15 genera, with 53% of the isolates recovered from the sponge Halichondria panicea. In contrast, metabarcoding revealed a high diversity of Actinobacteria, with Chlamys islandica exhibiting the highest uniqueness of Amplicon Sequence Variants (ASVs), as 21.76% of its ASVs wer
