N2 - A Gram-positive, motile, aerobic, rod-shaped, endospore-forming strain designated IRB4-01T was isolated from fermented African locust beans (Iru) obtained from Bodija market in the city of Ibadan, southwestern Nigeria, during a screening process from food-related sources. IRB4-01T grew at 10-50 °C (optimum, 35-37 °C), pH 6-10 (optimum, pH 7) and in 0-6 % NaCl (optimum, 1-3 %). Phylogenetic analyses based on 16S rRNA and combined short- and long-read genome sequencing revealed that IRB4-01T is closely related to Lysinibacillus cavernae SYSU K30005T and Lysinibacillus boronitolerans 10aT. The cell-wall peptidoglycan type was A4α (Lys-Asp), containing the diagnostic diamino acid lysine. The major polar lipids in strain IRB4-01T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified phospholipid, while the predominant menaquinone was MK-7. The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0. Genomic DNA G+C content was 37.4 mol%, while the digital DNA-DNA hybridization revealed 33.6 and 32.3 % relatedness to L. cavernae SYSU K30005T and L. boronitolerans 10aT, respectively. Based on phenotypic, physiological and chemotaxonomic characteristics, as well as genome comparisons, strain IRB4-01T represents a novel species of the genus Lysinibacillus, for which the name Lysinibacillus irui sp. nov. is proposed. The type strain is IRB4-01T (NCIMB 15452T=LMG 32887T). Hybrid genome data are provided on the NCBI database using the Bioproject number PRJNA906010 and accession numbers CP113527 and CP113528. Additionally, a representative 16S rRNA sequence is available with the GenBank accession number OQ566940.
