英文摘要	The bacterial strain M7D1(T) was isolated from samples of the rhizosphere of desert bloom plants on the Atacama region located in northern Chile as part of a study intended to isolate nitrifying bacteria in this adverse environment. It was previously identified as belonging to the Pseudomonas fluorescens group. In this study, the phylogenetic analysis of the 16s RNA, gyrA, rpoB and rpoD genes confirmed that this strain belongs to this group, especially Sub Group (SG) Koreensis, but it represents a potential new species. Additionally, the average nucleotide identity confirmed this as the highest identity value (0.92) with Pseudomonas moraviensis LMG 24280, which is lower than the 0.94 threshold established to classify two strains within the same species. The strain M7D1(T) shared a similar fatty acids methyl ester profile than the type strains of other Pseudomonas spp. previously described. Furthermore, it can be differentiated phenotypically from other related species of SG P. koreensis. Based on these results, the existence of a new species of Pseudomonas is demonstrated, for which the name Pseudomonas atacamensis is proposed. This strain presented a set of genes associated with plant growth-promoting rhizobacteria and it is a good candidate to be used for recovery of contaminated soils. However, more studies are required to demonstrate whether this bacterium is non-pathogenic, can survive in the presence of toxic compounds and promote growth or help to the stress management of plants.
