Strain PDF4T showed highest 16S rRNA gene sequence similarity to strain PDF10 (99.5 %), Brevibacillus brevis DSM 30T (98.9 %), Brevibacillus parabrevis DSM 8376T (98.6 %) and Brevibacillus formosus DSM 9885T (98.5 %); similarities to other species of the genus Brevibacillus were less than 98.5 %. The predominant fatty acids of strain PDF4T were anteiso-C15 : 0 (60.0 %) and iso-C15 : 0 (22.3 %). The polar lipids of strain PDF4T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, an unknown phospholipid, two unknown lipid, an unknown aminophospholipid and two unknown aminolipids. MK-7 was detected as a sole respiratory quinone, and the cell wall of strain PDF4T contained meso-diaminopimelic acid. The DNA G+C content of strain PDF4T was 51.7 mol%. DNA–DNA hybridization showed less than 60 % relatedness between strain PDF4T and type strains of the most closely related species given above. Based on these data, the two strains are considered to represent a novel species of the genus Brevibacillus, for which the name Brevibacillus gelatini sp. nov. is proposed. The type strain is PDF4T ( = NCCB 100559T = DSM 100115T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000780
