Mycobacteriales
The Mycobacteriales are an order of bacteria. The current description is genome-based, per Gupta 2019 emendation. Most members produce mycolic acids. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN). Terminology ''Mycolata'' has been used as a non-taxonomic term for mycolic acid-containing Actinobacteria. Mycobacteriales includes all such species, but it also includes some without mycolic acid, making these two terms imperfect, paraphyletic, aliases.

Mycolic Acids
Mycolic acids are long fatty acids found in the cell walls of Mycobacteriales taxon, a group of bacteria that includes ''Mycobacterium tuberculosis'', the causative agent of the disease tuberculosis. They form the major component of the cell wall of many Mycobacteriales species. Despite their name, mycolic acids have no biological link to fungi; the name arises from the filamentous appearance their presence gives Mycobacteriales under high magnification. The presence of mycolic acids in the cell wall also gives Mycobacteriales a distinct gross morphological trait known as " cording". Mycolic acids were first isolated by Stodola ''et al.'' in 1938 from an extract of ''M. tuberculosis''. Mycolic acids are composed of a longer beta-hydroxy chain with a shorter alpha-alkyl side chain. Each molecule contains between 60 and 90 carbon atoms. The exact number of carbons varies by species and can be used as an identification aid. Most mycolic acids also contain various functional gr ...

Dietziaceae
''Dietzia'' is a Gram-positive bacterial genus from the family Dietziaceae which occur in many different habitats including humans and animals. The species ''Dietzia maris'' is a human pathogen A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as ''Pneumocystis'') is mainly the responsibility .... The genus ''Dietzia'' is named after the American microbiologist Alma Dietz.

Gordoniaceae
The Gordoniaceae are a family of bacteria in the order of Actinomycetales The Actinomycetales is an order of Actinomycetota. A member of the order is often called an actinomycete. Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern. Some actinomycet ....

Hoyosellaceae
The Nocardiaceae are a family of aerobic, non-fastidious, high G+C, Gram-positive actinomycetes that are commonly found in soil and water. Members of this family have been isolated from Antarctic soils. Nocardiaceae present coccobacilli, filamentous or, rarely, fragmented and palisading forms, and filamentous species grow in a branching morphological pattern similar to fungal hyphae.Bitton, G. ''Wastewater Microbiology''. "Foam Microbiology.page 229 Genomics The Nocardiaceae form a monophyletic clade within the Corynebacteriales in both 16S rRNA and protein-based phylogenetic trees. A number of conserved signature indels and conserved signature proteins have been identified which are uniquely found in the genera ''Nocardia'' and ''Rhodococcus'', supporting a close relationship between the two genera. Recent proposals have been made, based on 16S rRNA signature nucleotides and chemotaxonomic markers, to add the genera ''Gordonia'', ''Skermania'', ''Williamsia'', ''Millisia'' ...

Mycobacteriaceae
''Mycobacteriaceae'' is a family of bacteria in the phylum Actinomycetota. Its name is derived from the ''Mycobacterium'' genus, which includes pathogens known to cause serious diseases in mammals, including tuberculosis (''Mycobacterium tuberculosis, M. tuberculosis'') and leprosy (''Mycobacterium leprae, M. leprae'') in humans. The Greek language, Greek prefix ''myco-'' means 'fungus', alluding to the Mold (fungus), mold-like appearance of these organisms on agar plates.

Tsukamurellaceae
''Tsukamurella'' is a Gram-positive, non-spore-forming, rod-shaped and obligate aerobic bacterial genus from the family of Tsukamurellaceae. Most of the strains of ''Tsukamurella'' degrade starch Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diet .... Some ''Tsukamurella'' species can cause infections in humans.
