A piezotolerant, H2O2-tolerant, heavy-metal-tolerant, slightly halophilic bacterium (strain NBT06E8T) was isolated from a deep-sea sediment sample collected from the New Britain Trench at depth of 8900 m. The strain was aerobic, motile, Gram-stain-negative, rod-shaped, oxidase-positive and catalase-positive. Growth of the strain was observed at 4–45 °C (optimum, 30 °C), at pH 5–11 (optimum, pH 8–9) and in 0.5–21 % (w/v) NaCl (optimum, 3–7 %). The optimum pressure for growth was 0.1–30 MPa with tolerance up to 60 MPa. Under optimum growth conditions, the strain could tolerate 15 mM H2O2. Resuls of 16S rRNA gene sequence analysis showed that strain NBT06E8T is closely related to Halomonas aquamarina DSM 30161T (99.5%), Halomonas meridiana DSM 5425T (99.43%) and Halomonas axialensis Althf1T (99.35%). The digital DNA–DNA hybridization values between strain NBT06E8T and the three related type strains, H. aquamarina , H. meridiana and H. axialensis , were 30.5±2.4 %, 30.7±2.5% and 31.5±2.5 %, respectively. The average nucleotide identity values between strain NBT06E8T and the three related type strains were 86.26, 86.26 and 83.63 %, respectively. The major fatty acids were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c) and C16 : 0. The predominant respiratory quinone detected was ubiquinone-9 (Q-9). Based on its phenotypic and phylogenetic characteristics, we conclude that strain NBT06E8T represents a novel species of the genus Halomonas , for which the name Halomonas piezotolerans sp. nov. is proposed (type strain NBT06E8T= MCCC 1K04228T=KCTC 72680T).

Two bacterial strains, BBH6T and BBH9, were isolated from a deep-sea sediment sample collected from the Chagos Trench, Indian Ocean, at a depth of 5904 m. The two strains were closely related in their 16S rRNA gene sequences (99.7 %), belonged to one genomic species and were virtually identical at the phenotypic level. Microbacterium barkeri DSM 20145T was the nearest phylogenetic neighbour to the new isolates, with 16S rRNA gene sequence similarity levels of 97.2–97.4 %. The new isolates exhibited levels of DNA–DNA relatedness of 32–34 % to M. barkeri and differed from it in a number of phenotypic characteristics. Therefore, it is suggested that strains BBH6T and BBH9 represent a novel species of the genus Microbacterium, for which the name Microbacterium indicum sp. nov. is proposed. The type strain is BBH6T (=LMG 23459T=IAM 15355T).
