Bhargavaea ullalensis sp. nov., isolated from coastal sand

Bhargavaea massiliensis sp. nov. and Dietzia massiliensis sp. nov., Novel Bacteria Species Isolated from Human Urine Samples in Nigeria

Two novel bacteria species designated Marseille-Q1000^T and Marseille-Q0999^T were isolated from urine samples of patients in Sokoto, Northwest-Nigeria. They were Gram-positive bacteria and belong to two different genera, Bhargavaea and Dietzia. The genome size and G + C content of Marseille-Q1000^T and Marseille-Q0999^T were 3.07 and 3.51 Mbp with 53.8 and 71.0 mol% G + C content, respectively. The strains exhibited unique phenotypic and genomic features that are substantially different from previously known bacterial species with standing in nomenclature. On the basis of the phenotypic, phylogenetic and genomic characteristics, strains Marseille-Q0999^T (= CSURQ0999 = DSM 112394) and Marseille-Q1000^T (= CSURQ1000 = DSM 112384) were proposed as the type strains of Bhargavaea massiliensis sp. nov., and Dietzia massiliensis sp. nov., respectively.

Bhargavaea changchunensis sp. nov. isolated from soil in China

A Gram-staining-positive, aerobic, rod-shaped (201802YP6^T) bacteria was isolated from soil, Northeast of China. Growth occurred at 10-40 °C (optimum 25-30 °C), at pH 6.0-8.0 (optimum 7.0) and at 0-2% NaCl. Based on 16S rRNA gene sequence analysis, the nearest phylogenetic neighbors of strain 201802YP6^T were identified as Bhargavaea cecembensis DSE10^T (99.52%), Bhargavaea beijingensis ge10^T (99.45%), Bhargavaea indica KJW98^T (99.45%), Bhargavaea ullalensis ZMA19^T (98.81%), and Bhargavaea ginsengi ge14^T (98.76%). Levels of similarity among strain 201802YP6^T and other Bhargavaea species were lower than 98.76%. GyrB amino acid sequence-based analysis supported the phylogenetic position and also distinguished strain 201802YP6^T from the other species of the genus Bhargavaea. DNA-DNA hybridization values between strain 201802YP6^T and B. cecembensis, B. beijingensis, B. indica, B. ullalensis, B. ginsengi were 43.5%, 43%, 32.5%, 30.5% and 20.4%, respectively. The DNA G + C content of strain 201802YP6^T was 51.23 mol%. The average nucleotide identity (ANI) of the draft genome was 87.04% to B. cecembensis DSE10^T. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, glycolipids, phosphatidylethanolamine, and phosphatidyllipid. The predominant menaquinone was MK-8. The major fatty acids were iso-C_15:0 (39.91%), anteiso-C_15:0 (28.86%), anteiso-C_17:0 (6.30%) and C_16:0 (6.13%). On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain 201802YP6^T represents a novel species of the genus Bhargavaea, for which the name Bhargavaea changchunensis sp. nov. is proposed. The type strain is 201802YP6^T (= CGMCC 1.13508^T = KCTC 33975^T).
