Title: The past, present and future of microbiome analyses

Journal Article · · Nature Protocols

Microbes evolved on Earth approximately 3.5 billion years ago and eventually occupied every habitable environment in its biosphere. While microorganisms are responsible for key functions on Earth including carbon and nutrient cycling and determining the health and disease of its inhabitants (i.e. plants and animals), >99% of the estimated trillions of microbes have yet to be discovered.1 In addition, high microbial diversity has made it difficult to study specific functions carried out by complex microbial communities within "microbiomes", such as those inhabiting the soil and human gut.2,3 Fortunately, technological advances over the last few decades have greatly facilitated studies of complex microbiomes and their functions. Here we will specifically discuss advances related to nucleic acid sequencing and mass spectrometry analyses that have enabled exploration and understanding of complex microbiomes in a range of environments and our own bodies.4,5,6,7
