However, under different salt concentrations, different halophilic archaea will have different adaptation mechanisms and physiological metabolic pathways, so there are significant differences between different strains. In this study, the basic morphology, growth characteristics, metabolic pathways, and genomic characteristics of different halophilic archaea in three salt environments were compared. The results showed that halophilic archaea showed different taxonomic characteristics in different salt environments, but there were also some similarities. The study has a certain reference value for in-depth understanding of the adaptation mechanism, ecology, and evolution of halophilic archaea.【Keywords】halophilic archaea; taxonomy; genomic characteristics; metabolic pathways; adaptation mechanism.
