Bacterial probiotics hold promise for enhancing coral health and stress resilience; however, their application to coral juveniles, which are critical for restorative aquaculture, remains underexplored. Here, we show that the microbiome of newly settled Acropora kenti is amenable to manipulation, with individual probiotic candidates inducing distinct microbiome responses that differed in their stability after the final inoculation. Three of the eight tested strains, Halomonas smyrnensis, Endozoicomonas acroporae and Roseivivax lentus, remained prevalent in the microbiome at least 5 days post-inoculation.

Biodegradation of microplastics facilitated by natural marine biofouling is a promising approach for ocean bioremediation. However, implementation requires a comprehensive understanding of how interactions between the marine microbiome and dominant microplastic debris types (e.g.

Bacteria associated with coral hosts are diverse and abundant, with recent studies suggesting involvement of these symbionts in host resilience to anthropogenic stress. Despite their putative importance, the work dedicated to culturing coral-associated bacteria has received little attention. Combining published and unpublished data, here we report a comprehensive overview of the diversity and function of culturable bacteria isolated from corals originating from tropical, temperate, and cold-water habitats.

Article Synopsis
  • Marine organisms, like stony corals, produce toxins and bioactive peptides for survival, but many of these, particularly in corals, remain underexplored.
  • Researchers isolated a 12-residue peptide called Hact-1 from a mushroom coral's tentacle extract, which has a unique sequence and a β-hairpin structure supported by a disulfide bond.
  • Despite its structural similarity to known toxins and venoms, Hact-1 shows no significant antibacterial or ion channel activity but has a limited effect on human immune cells, leaving its ecological role unclear.
