Physiological response of the moderately halophilic psychrotolerant strain sp. N1 to salinity change and low temperature.

The available information on synthesized compatible solutes in response to high medium salinity by bacteria of the genus is limited to studies of the mesophilic moderately halophilic strain DSM 3043. Therefore, there is a need for studies of representatives of other species of the genus of the family. A moderately halophilic psychrotolerant bacterium, strain N1, closely related to the species was isolated from the salt crust of a rock salt waste pile in Berezniki, Perm Krai, Russia.

Draft genome sequences of strains SMB35, sp. MH3R3-1 and sp. SMB17 from the Verkhnekamsk potash mining region of Russia.

Halomonads are moderately halophilic bacteria that are studied as models of prokaryotic osmoadaptation and sources of enzymes and chemicals for biotechnological applications. Despite the progress in understanding the diversity of these organisms, our ability to explain ecological, metabolic, and biochemical traits of halomonads at the genomic sequence level remains limited. This study addresses this gap by presenting draft genomes of SMB35, sp.

Naphthalene-degrading bacteria of the genus Rhodococcus from the Verkhnekamsk salt mining region of Russia.

Eight moderately halotolerant naphthalene-degrading strains of the genus Rhodococcus isolated from soil samples and slime pit bottom sediment of the Verkhnekamsk salt mining region of Russia were characterized by PCR amplification of repetitive bacterial DNA elements (rep-PCR) and identified by 16S ribosomal RNA gene sequence analysis. The diversity of their dioxygenase (nar-like) genes was investigated as these genes are known to be involved in naphthalene-degradation. The analysis of the nar-like genes identified revealed their heterogeneity in the strains under study and identity to the known sequences of nar-like genes of previously characterized from members of the genus Rhodococcus.
