Reactive oxygen species (ROS) are present in the pore water of intertidal permeable sediments, even in the anoxic zones. They control aerobic and anaerobic microbial degradation processes and thereby impact carbon turnover.

The accumulation and storage of nitrate by diatoms can contribute up to 1% of total pelagic nitrate and as much as 95% of total benthic nitrate, which indicates a potentially important contribution of diatoms to benthic nitrogen cycling, according to

Abstract Pseudomonas aeruginosa is an opportunistic pathogen and well characterized biofilm former. P. aeruginosa forms strong oxygen gradients inside biofilms due to rapid oxygen respiration in the top layers and the poor solubility of oxygen couple

Abstract Rhodolith beds built by free-living coralline algae are important ecosystems for marine biodiversity and carbonate production. Yet, our mechanistic understanding regarding rhodolith physiology and its drivers is still limited. Using three rh

Biological dinitrogen (N2) fixation is performed solely by specialized bacteria and archaea termed diazotrophs, introducing new reactive nitrogen into aquatic environments. Conventionally, phototrophic cyanobacteria are considered the major diazotrop

Abstract Background Dental plaque biofilms are the causative agents of caries, gingivitis and periodontitis. Both mechanical and chemical strategies are used in routine oral hygiene strategies to reduce plaque build-up. If allowed to mature biofilms

Corals are globally important calcifiers that exhibit complex responses to anthropogenic warming and acidification. Although coral calcification is supported by high seawater pH, photosynthesis by the algal symbionts of zooxanthellate corals can be p
