Novel Biotherapeutics To Modulate The Human Microbiome
Novel Biotherapeutics To Modulate The Human Microbiome

Ostia Sciences is a premier microbiome solutions company that specializes in discovering novel bacterial metabolites with antibacterial, antibiofilm, and immunomodulation activities. Our goal is to isolate beneficial microbes from the human oral microbiome, human breast milk, and fermented food, which are known to be rich sources of ribosomally synthesized and post-translationally modified peptides (RiPPs) and natural products with a range of biological activities.
There are more microbe cells than human cells in the human body. It is estimated that the human body is made up of approximately 30 trillion human cells, while the number of microbe cells is estimated to be around 100 trillion.














































The team’s exceptional track record includes delivering groundbreaking scientific studies, successfully bringing drugs to market, and driving advancements in the scientific community.
