| Abstract | Microbial communities are central to ecosystem functioning, contributing to nutrient cycling, bioremediation, and primary production. Yet, understanding in situ microbial interactions and their responses to environmental changes and chemical stressors remains a significant challenge with implications for evolution, human, animal, and environmental health, as well as biotechnology. Studies of microbial metabolites and metabolism provide valuable insights into microbial activity and microbe environment interactions. They reveal community responses, including acclimatation and adaptive strategies under stress, further linking metabolomes to biogeochemical processes and phenotypic traits in dynamic environments. Also, exometabolome analysis re-veals metabolic exchanges (e.g., cross feeding) shaping community diversity and function. However, gaps in spatiotemporal metametabolome dynamics and its ties to taxonomy hinder predictions of ecosystem structure and function, limiting actionable insights for conservation and management. Microbial biofilms in temperate climates, composed of most Life Kingdoms living in various habitats and driving ecological pro-cesses, could tackle this challenge. Recent studies use functional (photosynthesis, respiration) and structural (community composition) descriptors to assess stressor impacts on these communities but often focus narrowly on autotrophs or hetero-trophs, offering incomplete insights. These methods may lack sensitivity to detect early chemical stress or microbial interactions and overlook molecular mechanisms. Omics approaches including metabarcoding, metatranscriptomics, metaproteomics, and metametabolomics emerge as vital tools to comprehensively analyze biofilm responses, revealing taxonomic, genetic, and metabolic dynamics under environ-mental stress. Especially, untargeted metametabolomics analyzes thousands of me-tabolites from microbes environment interactions, revealing stress adaptations and bioactive chemicals, but faces technical hurdles in aquatic biofilm studies. Recent advances like mass spectrometry imaging and fluxomics improve spatial and tempo-ral metabolite tracking. Integrating these methods into a unified framework could de-code microbial acclimation and chemical interactions. Further multiomics integration could bridge gaps in understanding biofilm resilience and ecological functioning in the global change context. |
