Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

New Phytologist, EarlyView.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

First‐Time Demonstration of a Two‐Step Mechanism for Azo Dye Removal by Bacillus proteolyticus Using Molecular Docking and FT‐IR

Water Environment Research, Volume 98, Issue 8, August 2026.
Bacillus proteolyticus OA7, isolated from textile wastewater, efficiently removed Acid Red 88 (69.74%) and Acid Blue 193 (41.01%) through substrate‐dependent mechanisms. Acid Red 88 removal involved both biosorption and biodegradation, whereas Acid Blue 193 was mainly biosorbed. FT‐IR revealed functional group changes associated with EPS, proteins, and
