A Gram-stain positive, rod shaped aerobic bacterial strain designated Ka25(T) was isolated from a forest soil sample near Kasol, Himachal Pradesh, India. Based on 16S rRNA gene sequence analysis it was identified that strain Ka25(T) belongs to the class Actinobacteria and is most closely related to Nocardioides daejeonensis KCTC 19772(T) (97.2 %), Nocardioides dubius JCM 13008(T) (96.9 %), Nocardioides psychrotolerans CGMCC 1.11156(T) (96.8 %), Nocardioides pacificus DSM 27278(T)(96.7 %) and Nocardioides daphniae JCM 16608(T)(96.4 %) sequence similarity respectively. The chemotaxonomic properties of strain Ka25(T) are consistent with those of the members of the genus Nocardioides: MK-8(H4) is the predominant menaquinone, iso-C16 : 0, iso-C17 : 0 and C18 : 1ω9c were identified as the predominant cellular fatty acids and the cell-wall peptidoglycan is based on LL-2,6-diaminopimelic acid. The DNA G+C content of strain Ka25(T) was determined to be 71.6 mol %. The results of the polyphasic taxonomic analysis allowed a clear differentiation of strain Ka25(T) from all other members of the genus Nocardioides. Strain Ka25(T) is thus considered to represent a novel member of the genus Nocardioides, for which the name Nocardioides solisilvae sp. nov. is proposed. The type strain is Ka25(T) (=KCTC39528(T) =MCC2762(T)).

Two novel Gram-stain-positive, irregular rod-shaped bacterial strains, dk3136 and dk3543, were isolated from the faeces of Tibetan gazelle () in the Qinghai-Tibet Plateau of PR China. The cells were aerobic, oxidase-negative and catalase-positive. Colonies were yellowish, circular without any observable aerial mycelium after culturing at 28 ℃ for 3 days on brain-heart infusion (BHI) agar with 5 % sheep blood.

A Gram-stain-negative, aerobic, and motile strain, TJ48, was isolated from pakchoi-cultivated soil contaminated with Cd and Pb in Xinxiang (China). Cells of the strain were rod-shaped and colonies on LB agar were faint yellow. Strain TJ48 was positive for catalase and oxidase and the optimal condition for growth was 28 °C, with 1% (w/v) NaCl and at pH 7.

An oval to rod-shaped, phototrophic, purple non-sulfur bacterium, strain JA192(T), was isolated from an enrichment culture of a pasteurized rhizosphere soil sample from a field cultivated with jowar (sorghum) collected from Godumakunta village near Hyderabad, India. Strain JA192(T) is Gram-negative, motile and produces endospores. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that the strain JA192(T) is closely related to Rhodobacter sphaeroides 2.
