What is it about?
This study explores the hidden world of bacteria in marine biofilms, which are crucial for sustainable aquaculture. Using advanced DNA sequencing, we investigated the types of bacteria present in two different kinds of biofilms – one relying on light (phototrophic) and another on organic matter (heterotrophic) – over 30 days. We discovered that Proteobacteria are dominant, but a total of 27 different bacterial species play vital roles, especially in recycling nitrogen and sulfur, and maintaining the biofilm structure. Some of these species were found for the first time in these environments. Our findings highlight the complex bacterial networks that drive these systems, suggesting they are critical for efficient nutrient cycling and overall health in aquaculture.

Why is it important?
Understanding these bacterial communities is vital for optimizing microbial-based aquaculture systems. This knowledge can lead to more efficient nutrient recycling, improved water quality, and healthier farmed organisms, revolutionizing sustainable seafood production.
Perspectives
As authors, we believe this research opens doors for designing "designer biofilms" tailored for specific aquaculture needs. Future studies could focus on the functional roles of newly identified bacteria and their interactions with farmed species, potentially leading to probiotic applications or enhanced bioremediation strategies for aquaculture waste.
