Thiothrichales
Thiothrichales is a class of bacteria that belong to the phylum Actinobacteria. This class is characterized by its members having a unique type of cell wall that contains thiothricholic acid, a unique fatty acid. This acid is responsible for the distinctive yellow color often observed in Thiothrichales species. The class is further divided into several orders, including Thiothrichales, which is named after the type genus Thiothrix. Members of this class are typically found in soil and water environments, where they play roles in nutrient cycling and biodegradation. They are also known for their ability to form complex, branching structures, which can be observed under a microscope. Despite their ecological importance, the genetic and metabolic pathways of Thiothrichales are still not fully understood, making them a subject of ongoing research in microbiology.
