Chloroflexota

Chloroflexota is a bacterial phylum containing diverse lineages, including filamentous organisms, anoxygenic phototrophs, and heat-loving species. Its members vary widely in metabolism and habitat.

Bacteria: Bacteria are a domain of single-celled prokaryotic organisms lacking a membrane-bound nucleus. Chloroflexota is one phylum within this broad domain of life.
Anoxygenic photosynthesis: Anoxygenic photosynthesis uses light to drive electron transfer without producing oxygen from water. Some Chloroflexota use this form of photosynthesis in illuminated, oxygen-poor environments.
Chloroflexus aurantiacus: Chloroflexus aurantiacus is a filamentous, thermophilic, photosynthetic bacterium found in hot-spring microbial mats. It is a well-studied model for phototrophy and carbon metabolism in the phylum.
Bacterial taxonomy: Bacterial taxonomy names and classifies bacteria according to their traits and evolutionary relationships. The phylum's name and boundaries reflect changing approaches to bacterial classification.
Bacterial phylum: A bacterial phylum is a major taxonomic grouping of related bacterial lineages. This rank places Chloroflexota among broad bacterial branches.
Chlorosomes: Chlorosomes are large light-harvesting antenna structures found in certain photosynthetic bacteria. Chloroflexus species use chlorosomes to capture light efficiently under dim conditions.
Roseiflexus: Roseiflexus is a genus of filamentous bacteria found in hot-spring microbial mats. Its species illustrate phototrophic Chloroflexota that differ from Chloroflexus in light-harvesting structures.
Phylogenetics: Phylogenetics is the study of evolutionary relationships among organisms using inherited characteristics and molecular data. It provides the framework for interpreting relationships among Chloroflexota lineages.
Bacterial cell structure: Bacterial cell structure includes the membrane, cell wall, cytoplasm, and genetic material of prokaryotic cells. Cell envelopes and shapes vary among the phylum's filamentous and other members.
Bacteriochlorophyll: Bacteriochlorophylls are photosynthetic pigments that absorb light at wavelengths often distinct from those absorbed by chlorophylls in plants. These pigments power light-driven growth in phototrophic members of the phylum.
