Harnessing the vast, unseen world of microbes to improve business performance and make our lives better.

The microbiome around us is the most complex,
untapped dataset on Earth.

The microbiome is the trillions of interacting bacteria, fungi, algae and viruses that inhabit every inch of our world: our bodies, our stuff, our homes, and our cities. We make decisions every day based on the visible world around us. Yet much of our lives is shaped by what we cannot see.

Decoding the microbiome

With Phylagen’s technology and our proprietary databases it is possible to monitor, map and manage microbiomes. We combine bioinformatic analytics with scalable, high performance computing to determine and interpret complex genetic signatures and provide a powerful new decision-making tool for businesses.

Revealing the microbiome

The cost of DNA sequencing has dropped over 100,000 fold in the past decade. Phylagen generates terabytes of valuable microbiome sequence data under fast turnaround times at affordable cost, and leverages the data from this unseen universe by rapidly generating complex genetic profiles of entire microbial communities.

Optimizing microbiomes of a Fortune 50 customer


The above network depicts over 54 million DNA sequences and 30 billion base pairs from a customer deployment. Using advanced bioinformatics, microbiome data and metadata was analyzed, classified and clustered, revealing hidden correlations and genetic information to improve business performance.

Dr. Jonathan Eisen
Dr. Jonathan EisenScientific Advisor, UC Davis

Dr. Jonathan Eisen is a Professor at the Genome Center at the University of California, Davis and holds appointments in the Department of Evolution and Ecology in the College of Biological Sciences and the Department of Medical Microbiology and Immunology in the School of Medicine.

Dr. Eisen’s research focuses on communities of microbes. His overarching research goal is to create a “Field Guide to Microbes” – such as exists for birds or trees. He is widely known as a leading authority on studies of microbes based on DNA sequencing, is an author on more than 300 papers on this topic, and is one of the most highly cited researchers in the field.

His research focuses on the mechanisms underlying the origin of novelty (how new processes and functions originate). Most of his work involves the use of high-throughput DNA sequencing methods to characterize microbes and then the use and development of computational methods to analyze this type of data. In particular, his computational work has focused on phylogenomics, the integration of evolutionary analysis with genome analysis. Currently he is using sequencing and phylogenomic methods to study microbes directly in their natural habitats (i.e., without culturing). The main habitats he studies currently are microbiomes of plants, animals and the built environment.

Prior to moving to UC Davis he was on the faculty of The Institute for Genomic Research (TIGR) in Rockville, Maryland. He earned his PhD in Biological Sciences from Stanford University, and his AB in Biology from Harvard College. Dr. Eisen was elected to the American Academy of Microbiology in 2012.

White House Announces Microbiome Initiative

Jessica Green was among a small group of experts assembled recently by the White House Office of Science and Technology Policy to discuss the status of microbiome research. The event coincided with the launch of the National Microbiome Initiative, a call to action to advance microbiome science. The Obama administration announced steps to advance understanding of microbiomes and their influence on human health, climate change, food security and national security. Green joined a consortium of scientists in co-authorizing papers in Science magazine and mBio calling for new research tools to unlock the secrets of Earth’s microbial communities.

Wherever You Go, Your Personal Cloud Of Microbes Follows

Remember Pig-Pen? The little kid from Charles Schulz’s Peanuts cartoons who walked around in a cloud of dirt? Well, the human body does spew a cloud, but instead of dirt it contains millions of microorganisms. “It turns out that that kid is all of us,” says lead researcher James Meadow. “It’s just a microscopic cloud that’s really hard to see.” Each of us carries around millions of microorganisms – including bacteria, fungi and viruses — on the inner and outer surfaces of our bodies. Most of them aren’t dangerous. In fact, growing evidence indicates that they help us in lots of ways.

Designing a Hospital to Better Fight Infection

Every building appears to have its own unique microbiome, depending on how it is built and operated, who uses it and what they do there, said University of Oregon microbiologist Jessica Green, who helped pioneer the field. “We know microbes in buildings are relevant to human health,” she said. In hospitals, for example, the air that many patients breathe, recycled through heating and air-conditioning systems, concentrates human-related bacteria and potential pathogens, compared with patient rooms with open windows where outdoor air can circulate, according to Dr. Green’s 2012 study of Providence Milwaukie Hospital in Portland.

Mobile phones carry owners’ bacterial ‘fingerprint’

More than 80% of the common bacteria that make up our personal bacterial “fingerprints” end up on their screens, a study suggests.  “We are ultimately interested in the possibility of using personal effects as a non-invasive way to monitor our health and our contact with the surrounding environment. We share more than an emotional connection with our phones – they carry our personal microbiome”, said lead researcher Dr James Meadow.
