Mycolicibacillus is a genus of Gram-Positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales. [1]
Members of Mycolicibacillus were demarcated from the larger genus Mycobacterium in 2018 by Gupta et al. based on evidence from various phylogenetic trees constructed based on conserved genome sequences, comparative genomic analyses and average amino acid identity values. [1] In addition to this genus, the study proposed the division of Mycobacterium into a total of five distinct genera, which was met with some resistance by some of the scientific community. The resistance was based on the grounds that Mycobacterium contains some clinically relevant species and name changes might cause confusion among clinicians and other researchers. [3]
In 2020, Yamada et al. analyzed the fundamental morphological properties of the new genera, including the cell diameter, cell length, cell perimeter, cell circularity and aspect ratio, and determined that there were significant differences between the five genera, thus supporting the new division. [4]
The name Mycolicibacillus is derived from the Latin noun acidum mycolicum (translates to mycolic acid) and the Latin noun bacillus (translates to small staff or rod). Together the name refers to a genus of mycolic acid-containing, rod-shaped bacteria. [1]
While majority of the genus are slow growing bacteria species (taking more than seven days to form colonies), some do display intermediate growth rates (taking 5–15 days to form colonies). All species are nonchromogenic. Species are not thought to be pathogenic, although some have been isolated form human patients with pulmonary dysfunction. The genome size for the members of Mycolicibacillus ranges from 3.89–4.08 Mbp and their G+C content is 69.4 mol%. 22 unique conserved signature proteins (CSPs) were identified for this genus.
The phylogeny of Mycolicibacillus is based on 16S rRNA analysis. [1]
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 and leprosy in humans. The Greek prefix myco- means 'fungus', alluding to this genus' mold-like colony surfaces.

Mycolicibacillus koreensis is a slow-growing, non-chromogenic species of Mycolicibacillus originally isolated from the sputum of a human patient. It grows at temperatures from 25 to 37 °C and is susceptible to quinolones. The genome of M. koreensis contains a tRNA array that contains a long non-coding RNA called GOLDD.
