TL;DR
A new genus and a new species are proposed, Prauseria antiqua gen. nov., with the type strain L44385T (= VKM Ac-2616T), with the highest sequence similarity to the type strains of Haloactinopolyspora alkaliphila and Jiangella aurantiaca.
Two actinobacterial strains, DSM 43699T and JZT32T, isolated from water and soil samples collected in Germany and Tunisia, respectively, were investigated using comprehensive polyphasic taxonomic studies. The morphological and phenotypic features of the strains were consistent with those of members of the genera Microm...
A Gram-positive, non-spore-forming, rod-shaped actinobacterium, designated strain Le1T, was isolated from root nodules of Lupinus luteus cultivated in volcanic soils of southern Chile. Phylogenetic analysis based on the 16S rRNA gene placed strain Le1ᵀ within the genus Leifsonia, showing the highest sequence similarity...
Two Gram-stain-positive, non-motile actinomycetes, designated Or2-10aT and 21So2-11T, were isolated from ornithogenic and pristine soils collected on Ardley Island, Fildes Peninsula, King George Island, maritime Antarctica. 16S rRNA gene sequence analysis revealed that strains Or2-10aT and 21So2-11T showed the highest...
Two novel strains, designated SO4-18T and SO4-13T, were isolated from a mixture of oil production fluid sourced from Shengli Oilfield in China. Cells of the isolates were Gram-stain-positive, facultatively anaerobic, non-motile and piliated. Growth occurred at 4-37 °C (optimum 30 °C), pH 6.0-9.0 (optimum pH 8.0) and up...
The 16S rRNA gene sequence similarity, genomic relatedness, phylogenetic tree topology, and phenotypic characteristics supported the taxonomic independence of the isolate as a novel species in the genus Dechloromonas.
The findings suggest that Quadrisphaera strains possess metabolic pathways relating to useful plant bioactive compound production, such as brassinosteroid, diterpenoid, and isoquinoline alkaloid biosynthesis and xenobiotic biodegradation, and 1,1,1-Trichloro-2,2-bis(4-chlorophenyl)ethane (DDT) degradation.
