Solibacillus is a genus of Gram positive, rod shaped, spore-forming bacteria.
The first member of Solibacillus was first isolated in 1999, and was originally called Bacillus silvestris. However, further studies on B. silvestris found that the organism belonged in a separate genus. Solibacillus silvestris was proposed, referring to its original designation as a member of Bacillus, and the fact that the species was first isolated from soil.[2][3] Bacillus isronensis was later reclassified as Solibacillus isronensis.[4] S. isronensis was isolated from cryotubes that were used to collect air samples from high altitudes, and S. kalamii was found in an air filter from the International Space Station.[5]
In 2020, the family Planococcaceae was merged with the family Caryophanaceae due to nomenclature rules under the International Code of Nomenclature of Prokaryotes.[6] In addition, the family Caryophanaceae underwent several taxonomic changes to account for the large number of phylogenetically unrelated species that were misclassified.[6] Using comparative genomic analyses, the study identified several unique molecular markers (specifically conserved signature indels) could serve as a reliable means to distinguish genera such as Solibacillus within the family.[6]
Molecular Signatures
edit12 conserved signature indels (CSIs) were identified through genomic analyses for this genus in the following proteins: flagellar hook–basal body protein, aminodeoxychorismate lyase, VOC family protein, DNA topoisomerase IV subunit A, DegV family protein, helicase–exonuclease AddAB subunit AddB, multidrug resistance efflux transporter family protein, heme-dependent peroxidase, methionine ABC transporter ATP-binding protein, tRNA 4-thiouridine(8) synthase ThiI, and AAA family ATPase.[6] These CSIs provide a reliable molecular method for distinguishing Solibacillus species from other genera within the family Caryophanaceae and all other bacteria.[citation needed]
Phylogeny
editThe currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[1] and National Center for Biotechnology Information (NCBI)[7]
