Abstract
A novel endophytic actinobacterium, designated strain YIM 690053T, was isolated from healthy stems of Salsola ferganica Drob, and was characterized using a polyphasic taxonomic approach. The strain formed well-branched substrate mycelia with no fragmentation, and abundant aerial mycelia that differentiated into long spores. The strain was found to grow at 10–55 °C, pH 6.0–10.0 and in the presence of 0–7 % (w/v) NaCl. The genomic DNA G+C content was determined to be 70.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 690053T belongs to the genus Marinactinospora, and it shared the highest 16S rRNA gene sequence similarity with Marinactinospora thermotolerans SCSIO 00652T (98.96 %). However, the DNA–DNA relatedness values between the two strains was 37.85 ± 2.77 %. Based on the differences in the molecular and biochemical characteristics from its closest relative, strain YIM 690053T is concluded to represent a novel species of the genus Marinactinospora, for which the name Marinactinospora endophytica sp. nov. is proposed. The type strain is YIM 690053T(=KCTC 29664T = DSM 46799T).
