Purple sulfur bacteria - Wikipedia
The purple sulfur bacteria (PSB) are part of a group of Pseudomonadota capable of photosynthesis, collectively referred to as purple bacteria. They are anaerobic or microaerophilic, and are often found in stratified water environments including hot springs, stagnant water bodies, as well as microbial mats in intertidal zones.
An Overview of Purple Bacteria: Systematics, Physiology, and …
Purple sulfur bacteria differ from purple nonsulfur bacteria on both metabolic and phylogenetic grounds, but species of the two major groups often coexist in illuminated anoxic habitats in nature.
Purple bacteria - Wikipedia
Purple sulfur bacteria are named for the ability to produce elemental sulfur. They are included in the class Gammaproteobacteria, in the two families Chromatiaceae and Ectothiorhodospiraceae. While the former family stores the produced sulfur inside the cell, the latter sends the sulfur outside the cell. [5] .

8.9B: Anoxygenic Photosynthetic Bacteria - Biology LibreTexts
Dec 24, 2022 · The purple sulfur bacteria are a group of Proteobacteria capable of photosynthesis. They are anaerobic or microaerophilic, and are often found in hot springs or stagnant water. Unlike plants, algae, and cyanobacteria, they do not use water as their reducing agent, and so do not produce oxygen.
Purple photosymbioses: Current Biology - Cell Press
Mar 13, 2023 · Purple photosymbioses are associations between a heterotrophic eukaryote and intracellular purple bacteria. These associations constitute a type of photosymbiosis as they involve photosynthetic symbionts that use light as an energy source and fix atmospheric carbon dioxide into biomass.
