Chloroflexales is an order of bacteria in the class Chloroflexia.[1] The clade is also known as filamentous anoxygenic phototrophic bacteria (FAP),[2] as the order contains phototrophs that do not produce oxygen. These bacteria are facultative aerobic.[3] They generally use chemotrophy when oxygen is present and switch to light-derived energy when otherwise. Most species are heterotrophs, but a few are capable of photoautotrophy.[2]
The order can be divided into two suborders. Chloroflexineae ("Green FAP", "green non-sulfur bacteria") is the better-known one. This suborder uses chlorosomes, a specialized antenna complex, to pass light energy to the reaction center. Roseiflexineae ("Red FAP") on the other hand has no such ability. The named colors are not absolute, as growth conditions such as oxygen concentration will make a green FAP appear green, brown, or reddish-orange by inducing changes in pigment composition.[2]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[4] and National Center for Biotechnology Information (NCBI).[5]
