Abstract

Ly.si.ni.ba.cil'lus. N.L. neut. n. lysinum lysine; L. masc. n. bacillus a small staff or rod; N.L. masc. n. Lysinibacillus lysine bacillus, referring to the presence of the Lys–Asp type of peptidoglycan in the cell wall. Firmicutes / Bacilli / Bacillales / Bacillaceae / Lysinibacillus The genus Lysinibacillus was proposed in 2007 to describe a phylogenetic and physiological distinct group of Bacillaceae that exhibit an l ‐Lys‐ d ‐Asp (A4α) cell wall composition. Twenty‐one Lysinibacillus species were validly published between 2007 and 2018, and five former Bacillus species were moved to Lysinibacillus . Lysinibacillus boronitolerans serves as the type species. Lysinibacillus strains have been isolated from an impressive diversity of environments ranging from pristine and contaminated soils to plants, aquatic environments, indoor air, food, insects, animal waste, a cellular phone screen, and even an organic solvent. The genus is primarily Gram‐positive and aerobic with cells consisting in motile rods capable of forming terminally located bulging endospores. All species are catalase‐positive and typically have iso‐C 15:0 as the primary fatty acid and MK‐7 as the primary menaquinone system. Diphosphatidylglycerol and phosphatidylglycerol are the major polar lipids. The members of the genus Lysinibacillus cannot reduce nitrate, are unable to produce indole, and are incapable of utilizing 2‐ketogluconate, capric acid, d ‐arabinose, gentiobiose, indole, myo ‐inositol, stachyose, starch, β‐gentiobiose, and β‐methyl‐xyloside. While the Lysinibacillus genus is best known for a clonal lineage of mosquitocidal isolates because of their widespread use in mosquito control, Lysinibacillus strains also have potential in biotechnological applications and bioremediation because of their enzymatic capabilities and tolerance to a variety of pollutants.
