First description of a new uncultured purple sulfur bacterium colonizing marine mangrove sediment in the Caribbean: Halochromatium-like PSB from Guadeloupe [PDF]

open access: yes, 2018
International audienceHere, we report the first description of a marine purple sulfur bacterium (PSB) from sulfide-rich sediments of a marine mangrove in the Caribbean. TEM shows that this new isolate contains intracytoplasmic vesicular membrane systems (

The occurrence of chromatiaceae in waste treatment lagoons and their utilisation to treat fellmongery effluent : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Biotechnology at Massey University [PDF]

open access: yes, 1979
A study of the occurrence of Chromatiaceae in waste treatment lagoons was made. To determine the important factors leading to their dominance, an investigation of the effect of various environmental parameters on the growth of a Chromatium species was ...

Geomorphic consequences of freshwater discharge and microbial mats in a macrotidal environment: The case of the beach of Dannes (northern France)

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This transdisciplinary study analyses the geomorphic consequences of microbial mats associated with freshwater outflows in a macrotidal environment. Microorganisms were identified using the DNA metabarcoding approach. SEM analysis of quartz collected from the beach surface provided data on the marine and aeolian forces, as well as biological processes ...

Anoxygenic photosynthesis with emphasis on green sulfur bacteria and a perspective for hydrogen sulfide detoxification of anoxic environments

open access: yesFrontiers in Microbiology
The bacterial light-dependent energy metabolism can be divided into two types: oxygenic and anoxygenic photosynthesis. Bacterial oxygenic photosynthesis is similar to plants and is characteristic for cyanobacteria.

Growth of Purple Sulfur Bacterium Thiocapsa sp. Shira_1 at Low Temperatures Characteristic of the Chemocline of Lake Shira [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2018
Forecasting the abundance of phototrophic sulfur bacteria in lakes is very important because 1) these bacteria are major consumers of hydrogen sulfide, and 2) fossil carotenoids of these bacteria are retrospective biomarkers of limnological conditions ...

High resolution analysis of fossil pigments, carbon, nitrogen and sulphur in the sediment of eight European Alpine lakes: the MOLAR project

open access: yesJournal of Limnology, 2000
A palaeoenvironmental reconstruction for the past 2-3 centuries of eight remote sites from northern to southern Europe was based on a number of palaeolimnological proxies, especially fossil pigments.

Seasonal Cycles in a Seaweed Holobiont: A Multiyear Time Series Reveals Repetitive Microbial Shifts and Core Taxa

open access: yesEnvironmental Microbiology, Volume 27, Issue 3, March 2025.
The red seaweed Gracilaria vermiculophylla holobiont exhibits strong seasonal succession. Its epibiotic microbial community shifts annually from winter to summer and back. The holobiont features a permanent core of year‐round present taxa and distinct seasonal cores, with taxa that consistently return during winter or summer. ABSTRACT Seasonality is an

A Previously Uncharacterized, Nonphotosynthetic Member of the Chromatiaceae Is the Primary CO_2-Fixing Constituent in a Self-Regenerating Biocathode [PDF]

open access: yes, 2015
Biocathode extracellular electron transfer (EET) may be exploited for biotechnology applications, including microbially mediated O_2 reduction in microbial fuel cells and microbial electrosynthesis.

Untangling the Primary Biotic and Abiotic Controls on Oxygen, Inorganic and Organic Carbon Isotope Signals in Modern Microbialites

open access: yesGeobiology, Volume 23, Issue 1, January/February 2025.
ABSTRACT Microbialites are organo‐sedimentary structures formed throughout most of the Earth history, over a wide range of geological contexts, and under a multitude of environmental conditions affecting their composition. The carbon and oxygen isotope records of carbonates, which are most often their main constituents, have been used as a widespread ...

Evaluation of Laser In Situ Scattering Instrument for Measuring Concentration of Phytoplankton, Purple Sulfur Bacteria, and Suspended Inorganic Sediments in Lakes [PDF]

open access: yes, 2001
A laser in situ scattering and transmissometry (Lisst-100) probe has been used for estimating the particle-size distribution of phytopankton, purple photosynthetic sulphur bacteria (Chromatiaceae), and suspended inorganic sediments in different lakes ...
