The reproduction process of Gram-positive protocells [PDF]
Scientific ReportsProtocells are believed to have existed on early Earth prior to the emergence of prokaryotes. Due to their rudimentary nature, it is widely accepted that these protocells lacked intracellular mechanisms to regulate their reproduction, thereby relying ...

Towards bioprocess engineering of cable bacteria: Establishment of a synthetic sediment. [PDF]
MicrobiologyopenIn this study, we successfully cultivated the cable bacteria strain Electronema aureum GS on a newly developed synthetic sediment, marking the first instance of such cultivation on synthetic rather than natural sediment. The combination of this synthetic sediment and a specially designed sediment bioreactor enables reproducible cultivation of cable ...

Large Filamentous Bacteria Isolated From Sulphidic Sediments Reveal Novel Species and Distinct Energy and Defence Mechanisms for Survival. [PDF]
Environ MicrobiolIn this study, we used micromanipulation and omics to analyse 15 large filamentous bacteria collected from sulphidic sediments off Chile. We discovered novel species from various phyla, and diverse metabolic pathways and defence mechanisms were identified, highlighting their adaptability to the sediment–water interface and resilience against phage ...

The microbiologist’s guide to membrane potential dynamics [PDF]
, 2020 All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

From two sensors to a single sensor: Better understanding of oxygen–sulfide interfaces
Limnology and Oceanography: Methods, Volume 21, Issue 10, Page 606-614, October 2023., 2023 Abstract Intense biogeochemical transformations in sediments and biofilms may occur over sub‐mm distances. Our current understanding of those transformations in such narrowly stratified environments has been facilitated by the introduction of microsensors.
