Purple bacteria - Wikipedia
Purple bacteria or purple photosynthetic bacteria are Gram-negative proteobacteria that are phototrophic, capable of producing their own food via photosynthesis. [1] . They are pigmented with bacteriochlorophyll a or b, together with various carotenoids, which give them colours ranging between purple, red, brown, and orange.
Pseudomonadota - Wikipedia
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. [10] Currently, they are considered the predominant phylum within the realm of bacteria. [11] They are naturally found as pathogenic and free-living (non-parasitic) genera. [11]
Purple Bacteria - an overview | ScienceDirect Topics
Purple bacteria form a heterogeneous group of microorganisms capable of growing under anoxic conditions by anoxygenic photosynthesis. They can be divided into purple nonsulfur bacteria, which are able to grow both phototrophically and in darkness, and purple sulfur bacteria, all of them capable to grow in the light but only few of them in the dark.

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.
