sp. nov., a novel antibiotic-producing member of the genus .

Strain TÜ4103 was originally sampled from Java, Indonesia and deposited in the Tübingen strain collection under the name ' sp.'. The strain was found to be an antibiotic producer as strain TÜ4103 showed bioactivity against Gram-positive bacteria, such as and in bioassays. Strain TÜ4103 showed 16S rRNA gene sequence similarity of 99.65 % to DSM 101999 and 98.82 % to DSM 44781 and DSM 44780. Genome-based phylogenetic analysis revealed that strain TÜ4103 is closely related to DSM 44780 and DSM 44781. The digital DNA-DNA hybridization values between the genome sequences of strain TÜ4103 and its closest phylogenomic relatives, strains DSM 44780 and DSM 44781, were 43.0 and 42.9 %, respectively. Average nucleotide identity (ANI) values support this claim, with the highest ANI score of 91.14 % between TÜ4103 and being closely followed by an ANI value of 91.10 % between and TÜ4103. The genome of TÜ4103 has a size of 7.91 Mb with a G+C content of 74.05 mol%. Whole-cell hydrolysates of strain TÜ4103 are rich in -diaminopimelic acid, and rhamnose, galactose and mannose are characteristic as whole-cell sugars. The phospholipid profile contains phosphatidylethanolamine, diphosphatidylglycerol and glycophospholipid. The predominant menaquinones (>93.5 %) are MK-9(H) and MK-9(H). Based on the phenotypic, genotypic and genomic characteristics, strain TÜ4103 (=DSM 114396=CECT 30712) merits recognition as the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
