Unravelling the carbon and sulphur metabolism in coastal soil ecosystems using comparative cultivation-independent genome-level characterisation of microbial communities. [PDF]
PLoS ONE, 2014 Bacterial autotrophy contributes significantly to the overall carbon balance, which stabilises atmospheric CO2 concentration and decelerates global warming.

Proceedings of the National Academy of Sciences, 1977 Previous reports of a relatively air-stable soluble hydrogenase from the photosynthetic anaerobe, Chromatium vinosum, have been substantiated. The properties of this enzyme, as seen in highly purified samples prepared by procedures that permit improved yields, are described. A possible role for flavin mediation is noted.

Limnology and Oceanography, Volume 68, Issue 11, Page 2492-2511, November 2023., 2023 Abstract The microbial ecology of meromictic lakes assessed with “omics” is still poorly studied compared to other aquatic systems. Here, a combination of metagenomics, high resolution sampling and detailed physical–chemical data gathering allowed to study the planktonic prokaryotic assemblages and metabolic capabilities in the crenogenic meromictic ...

Global Change Biology, Volume 28, Issue 18, Page 5575-5586, September 2022., 2022 We used 240 replicable oxic‐anoxic aquatic lab microcosms and four drivers (fertilizer, glyphosate, metal pollution, antibiotics) in all possible combinations at three different temperatures (20 °C/24 °C/28 °C) to shed light into consequences of multiple drivers on different levels of organization, ranging from species abundance to community and ...

The Depositional Record, Volume 8, Issue 1, Page 165-209, February 2022., 2022 Three active travertine sites were investigated in Central Italy to identify the types of carbonate precipitates and the associated microbial mats at varying physico‐chemical parameters. This study confirms that microbial communities in hydrothermal settings vary as a function of water temperature.

New Phytologist, Volume 232, Issue 2, Page 479-493, October 2021., 2021 Summary The development of photosynthesis was a highlight in the progression of bacteria. In addition to the photosystems with their structural proteins, the photosynthesis apparatus consists of different cofactors including essential carotenoids.

High Degree of Similarity between Chromatium vinosum and Chromatium minutissimum as Revealed by Riboprinting [PDF]
International Journal of Systematic Bacteriology, 1996 The riboprinting technique (restriction fragment length polymorphism [RFLP] analysis of PCR-amplified ribosomal DNA) was used to study five strains representing three species of the genus Chromatium. An RFLP analysis following digestion of the amplified small-subunit ribosomal DNA with 25 restriction enzymes revealed that the patterns obtained for all ...

MicrobiologyOpen, Volume 10, Issue 3, June 2021., 2021 We used a modified and highly replicated Winogradsky column approach for analyzing simultaneous global change effects (temperature and nutrient addition) on aquatic stratified microbial communities. We found that these global change treatments can have interaction effects and can differ between the oxic and anoxic layers and the community within ...

Niche partitioning of bacterial communities along the stratified water column in the Black Sea
MicrobiologyOpen, Volume 10, Issue 3, June 2021., 2021 The study aimed at describing the Black Sea microbial community taxonomic and functional composition within the range of depths spanning across oxic/anoxic interface, and to uncover the factors behind both their vertical and regional differentiation. It is suggested that regional differentiation within a well‐oxygenated zone is driven by the difference
