Functional Microbiomes at the Interface: Mediators in Marine Biofouling and Larval Settlement

Area of Science:

• Marine biology
• Microbial ecology
• Biotechnology

Background:

• Marine surfaces are colonized by microbial communities, initiating biofouling and influencing invertebrate larval settlement.
• Microbiomes act as crucial biochemical and biophysical interfaces in marine ecosystems.
• Biofouling impacts marine infrastructure and ecosystem services.

Purpose of the Study:

• To review gene-level processes in microbial functions related to biofouling and larval settlement.
• To evaluate how microbial metabolites affect larval recruitment in various marine invertebrates.
• To assess the role of omics-based approaches in understanding marine biofilm communities.

Main Methods:

• Literature review of gene-level processes (quorum sensing, EPS production).
• Analysis of microbial metabolite roles in larval settlement (corals, barnacles, polychaetes, bivalves).
• Evaluation of omics-based approaches for biofilm functional potential.

Main Results:

• Microbial functions like quorum sensing and EPS production are central to biofouling.
• Microbial metabolites significantly influence the settlement of diverse marine invertebrate larvae.
• Omics approaches reveal the functional capacity of marine biofilms.

Conclusions:

• Understanding microbial gene-level functions is critical for managing biofouling and larval settlement.
• Microbial interactions impact key ecosystem services, including habitat structuring and reef resilience.
• Further research using omics can enhance strategies for coastal infrastructure maintenance and marine conservation.
