TL;DR: In this paper, the authors studied the consequences of phytodetrital deposition and oxygen deficiency on the environment and benthic communities in Concepcion Bay and found that NH4 exchange showed a clear seasonal pattern, with influxes during the winter (7.6 4.9 mmol m 2 d 1, which accounts for 17% of the total NH4 efflux during the summer period (January and March).

TL;DR: Findings do not support a role of F. nucleatum or B. fragilis during colorectal beginning, while a potential role of the bacterial genera Prevotella and Acinetobacter was indicated, and requires further investigations.

TL;DR: This study examines in detail the architecture of the cell envelope of cable bacterium filaments by combining different sample preparation methods (chemical fixation, resin-embedding, and cryo-fixation) with a portfolio of imaging techniques (scanning electron microscopy and tomography, focused ion beam scanning electron microscope, and atomic force microscopy).

TL;DR: In this article, a microsensor for determination of apparent gas diffusivity in pore waters and biofilms is described, which is based on diffusion from an internal gas reservoir, through an internal diffusion barrier positioned within the sensor tip and out into the surrounding medium.
