Almost 200 companies are actively exploring the linkage between diseases and the microbiome – millions of bacteria, fungi, protozoa and viruses that live inside and on the human body – in order to identify therapeutic targets. Scientists have called it the second genome, and in fact, the number of genes in the microbes making up one person's microbiome is estimated to be at least 200 times the number in the human genome.

Over the last decade, there has been rapid acceleration in scientific understanding of the composition and functions of the gut microbiota. Arranta is proud to be the leading CDMO focused on supporting the supply needs of these innovators.
