Abstrakt: The Permian Basin is a unique ecosystem located in the southwest of the USA. An unanswered question is whether the bacteria in the Permian Basin adapted to the changing paleomarine environment and survived in the remnants of Permian groundwater. In our previous study, a novel bacterial strain, Permianibacter aggregans HW001 T , was isolated from microalgae cultures incubated with Permian Basin waters, and was shown to originate from the Permian Ocean. In this study, strain HW001 T was shown to be the representative strain of a novel family, classified as 'Permianibacteraceae'. The results of molecular dating suggested that the strain HW001 T diverged ~ 447 million years ago (mya), which is the early Permian period (~ 250 mya). Genome analysis was used to access its potential energy utilization and biosynthesis capacity. A large number of transporters, carbohydrate-active enzymes and protein-degradation related genes have been annotated in the genome of strain HW001 T . In addition, a series of important metabolic pathways, such as peptidoglycan biosynthesis, osmotic stress response system and multifunctional quorum sensing were annotated, which may confer the ability to adapt to various unfavorable environmental conditions. Finally, the evolutionary history of strain HW001 T was reconstructed and the horizontal transfer of genes was predicted, indicating that the adaptation of P. aggregans to a changing marine environment depends on the evolution of their metabolic capabilities, especially in signal transmission. In conclusion, the results of this study provide genomic information for revealing the adaptive mechanism of strain HW001 T to the changing ancient oceans.
