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.

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.
