Marine biofilms: diversity, interactions and biofouling

Area of Science:

• Marine Biology
• Microbiology
• Environmental Science

Background:

• Marine biofilms are widespread microbial communities in marine environments.
• These communities exhibit diverse structures, functions, and metabolisms, responding dynamically to environmental shifts.
• Limited understanding exists regarding natural marine biofilm structures, functions, and their impact on global geochemical cycles.

Purpose of the Study:

• To review the current knowledge on marine biofilm dynamics, including diversity, abundance, and functions.
• To identify knowledge gaps and suggest future research directions in marine biofilm studies.
• To explore potential biotechnological applications derived from marine biofilms.

Main Methods:

• This review synthesizes existing literature on marine biofilms.
• It discusses microbial interactions mediated by cues like secondary metabolites and microbial structures.
• The review examines the role of biofilms in marine biofouling and their impact on marine industries.

Main Results:

• Marine biofilms are key mediators of biofouling, significantly impacting marine industries.
• Microbial cues within biofilms regulate inter-organism interactions, influencing community succession.
• Despite their importance, comprehensive data on natural marine biofilm structures and functions remain limited.

Conclusions:

• Further research is needed to fully elucidate the microbial community structures and functions of marine biofilms.
• Understanding marine biofilms is critical for addressing challenges in marine industries and harnessing biotechnological potential.
• Marine biofilms play a vital role in regulating marine ecosystems and geochemical cycles.
