Structure And Function Of The FMO Protein From The Photosynthetic Green Sulfur Bacteria
… is significantly divergent from the FMO found in green sulfur bacteria: GSB). This FMO has two distinct structural regions different from the FMOs from GSB and also shows distinct spectral properties. The collection of these different FMO complexes has greatly facilitated our understanding of this …

Light-Harvesting, Redox Control, and Biomimicry of the Photosynthetic Antennas of Green Sulfur Bacteria
The green sulfur bacteria (class Chlorobea) are obligately anaerobic photoautotrophic prokaryotes. Members of this bacterial class are found in anoxic, sulfur- or iron-rich environments such as hydrothermal vents and hot springs. These bacteria are champions of lowlight adaptation, with some …

In situ Metabolism and Biogeography of Phototrophic Consortia
… variability of pigment composition in green sulfur bacteria<< The relative composition of bacteriochlorophyll (BChl) homologs in five different strains of brown-colored green sulfur bacteria was investigated by HPLC-MS/MS and NMR analyses. In addition, the effect of incubation light …

Stable isotope and organic biomarker analysis of the late Proterozoic Coppercap formation in the MacKenzie Mountains
Sulfur and carbon stable isotope ratios and organic biomarker abundance were performed on drill core samples from the Coppercap Formation of the Coates Lake Group in the Windermere Supergroup of the MacKenzie Mountains to reconstruct an environmental condition proceeding the first Neoproterozoic …

Triplet Excitons in Natural Photosynthetic and Artificial Light Harvesting Systems: Measurement and Modeling.
… these mechanisms are two structures found in green sulfur bacteria: the chlorosome (an antenna containing ~100000 coupled BChl c, d, or e molecules with unexpectedly high photostability) and the Fenna-Matthews-Olson (FMO) complex (an auxiliary antenna containing eight seemingly unprotected …

Identification of chemoautotrophic microorganisms from a diffuse flow hydrothermal vent at EPR 9° North using 13C DNA Stable Isotope Probing and Catalyzed Activated Reporter Deposition-Fluorescence in situ Hybridization
… and acceptor species showed that Epsilonproteobacteria were the dominant chemoautotrophs with greater than 70% of the cells counted within the first 24 hours. 13C DNA SIP identified unique organisms not previously characterized from low temperature diffuse flow venting: green sulfur bacteria …

Optoelectronic properties and energy transport processes in cylindrical J-aggregates
… to the cylindrical chlorosomes (antenna) from green sulfur bacteria. This research utilizes optical spectroscopy and microscopy to study the supramolecular origins of the exciton transitions and fundamental nature of exciton energy transport in C8S3 artificial light harvesting systems. Two …

Investigation of chiral porphyrin aggregates with heterodyne-detected vibrational sum frequency generation spectroscopy
… light-harvesting "antennae" present in green sulfur bacteria chlorosomes. Imaging and spectroscopic studies indicate that the helical nanotubular TSPP aggregates are chiral and have distinct exciton contributions along different axes. However, the precise arrangement of TSPP monomers …

Metagenomic analysis of the biodiversity and seasonal variation in the meromictic Antarctic lake, Ace Lake
… of virus-host associations of phototrophic bacteria revealed that the availability of light, rather than viral predation, was probably responsible for seasonal variations in host abundances. Genomic variation in Synechococcus and Chlorobium populations, analysed using metagenome-assembled …
