Agromyces salentinus sp. nov. and Agromyces neolithicus sp. nov.
نویسندگان
چکیده
A polyphasic study was carried out to clarify the taxonomic position of two Gram-positive bacteria isolated from soil samples of the Grotta dei Cervi (Italy), a relatively unexplored hypogean environment. The strains, 20-5T and 23-23T, showed phenotypic and phylogenetic characteristics that were consistent with their classification in the genus Agromyces. 16S rRNA gene sequence comparisons revealed that the two strains formed distinct phyletic lines within the genus Agromyces. Based on 16S rRNA gene sequence similarity, chemotaxonomic data and the results of DNA-DNA relatedness studies, it is proposed that the two isolates represent two novel species of the genus Agromyces. Pronounced differences in a broad range of phenotypic characteristics and DNA G+C content distinguished the two strains from each other and from previously described species of the genus Agromyces. Two novel species are proposed: Agromyces salentinus sp. nov. (type strain, 20-5T=HKI 0320T=DSM 16198T=NCIMB 13990T) and Agromyces neolithicus sp. nov. (type strain, 23-23T=HKI 0321T=DSM 16197T=NCIMB 13989T).

The taxonomic position of Agromyces fucosus subsp. hippuratus is revised on the basis of molecular and phenotypic data. Phylogenetic analysis based on 16S rRNA gene sequences, DNA-DNA relatedness values and differences from other species in phenotypic traits revealed in this and earlier studies suggested reclassification of A. fucosus subsp. hippuratus as a separate species, Agromyces hippuratu...
متن کاملAgromyces arachidis sp. nov. Isolated from a Peanut (Arachis hypogaea) Crop Field
A Gram-positive, yellowish bacterium strain AK-1(T) was isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genus Agromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1(T) was closely related ...
متن کاملAgromyces subbeticus sp. nov., isolated from a cave in southern Spain.
An actinomycete, strain Z33(T), was isolated from a cyanobacterial biofilm in the Cave of Bats, near Zuheros (Cordoba, southern Spain). 16S rRNA gene sequence analysis showed that strain Z33(T) formed a distinct phyletic line within the genus Agromyces. This isolate could be readily distinguished from representatives of all recognized Agromyces species on the basis of a broad range of phenotypi...

A Gram-staining-positive, aerobic, non-motile and rod-shaped bacterium, designated P27(T), was isolated from a traditional fermented seafood. The isolate grew optimally with 0-2.0 % (w/v) NaCl and at pH 6-7 and 30 degrees C. The predominant menaquinones were MK-12 and MK-11. The major cellular fatty acids were anteiso-C(17 : 0), anteiso-C(15 : 0) and iso-C(16 : 0). The major cell-wall sugars we...
