Environment drives bacterial functional diversification. Molecular functional abilities of individual microbes and microbiomes from different envrionment conditions, such as temperature or salinity or even the sick or healthy individual gut, are clearly different. Understanding the functions encoded in the (meta)genomes of microbiomes is thus vital for mapping their environmental preferences. The high-throughput (meta)genomic sequencing, coupled with the growing computational resources, has unlocked new horizons. However, making sense of this deluge of data requires efficient and accurate analytical techniques. The attendees are expected to leave the presentation with understandings the concept of how environment impacts on micro[biom]e functions and computational tools that we built to facilitate the analysis.
