metadata.value: This study investigated the degradation of diesel fuel (DF) by an aerobic halotolerant strain, Dietzia sp. NDT10 (VKM Ac-2994D), under high salinity conditions. Dietzia sp. strain NDT10 has been isolated from diesel-contaminated rhizosphere soil of Dactylis glomerata L. on the territory of industrial production and processing of potassium salts (Solikamsk, Perm Krai, Russia). The 16S rRNA gene sequence analysis showed that the strain NDT10 is phylogenetically close (99.89 % similarity) to the type strains of two species, Dietzia maris DSM 43672T and Dietzia kunjamensis subsp. The ability of the strain NDT10 to degrade diesel fuel without salt and in the presence of up to 125 g NaCl/L was found. When adding 30, 50, and 70 g NaCl/L to the culture medium, the diesel fuel degradation ability of strain NDT10 was markedly increased, especially in the case of long-chain hydrocarbons (С15–С20) compared with short-chain hydrocarbons (С9–С14). An improvement in the degradative activity of Dietzia sp. NDT10 correlated with an increase in cell surface hydrophobicity in the presence of NaCl in the medium. Using the NDT10 strain as an example, a positive effect of diesel fuel components on the salt tolerance of bacteria was established. The results obtained can be used to develop biotechnological strategies for the clean-up of contaminated sites with DF and other petroleum products.
