Deep-sea cold seeps are formed by the leakage of hydrocarbons such as methane, creating unique eco-environments that foster novel and phylogenetically diverse prokaryotes, eukaryotes, and viruses. Cold seep microorganisms obtain energy and substances through chemosynthesis, driving the biogeochemical cycles of elements such as carbon, sulfur, and nitrogen, thereby maintaining the stability of the cold seep ecosystem. Cold seep habitats contain rich microbial genetic resources, especially enzymes and secondary metabolites produced under extreme conditions, which exhibit dehalogenating, nitrogen-fixing, and antimicrobial activities, with potential applications in agriculture, drug development, and environmental protection. Additionally, cold seep microorganisms are closely related to the environmental impact assessment of natural gas hydrate extraction and play a significant role in global climate change. To effectively develop the microbial genetic resources in deep-sea cold seeps, researchers should combine in situ sampling, sequencing, and culture methods with environmental parameter monitoring to explore the ecological roles and evolutionary mechanisms of these microorganisms, delve into their genetic resources, and investigate microbial responses during hydrate extraction. Such efforts will provide a scientific basis for comprehensively developing microbial genetic resources and hydrate resources in deep-sea cold seeps.
