Biofilm sediment
WebThe virulent vAh was detected in 35.4% of biofilm samples and 22.9% of sediment samples, suggesting that both environments serve as the major reservoir for this pathogen. Future monitoring efforts should focus on targeting sediment and biofilms since samples of these appear to naturally enrich for the presence of vAh and other Aeromonas species.

WebJan 11, 2024 · Furthermore, biofilms can be a CO 2 sink on the sediment surface, suggesting that they can accumulate carbon (Chen S. et al. 2024). Biofilms that are rapidly buried may decompose slower in an anaerobic environment than at the surface, allowing greater carbon preservation. Biofilms exist in a delicate balance with sediment deposition.
