Siderosorb™ Technology

Saccharomyces cerevisiae has been used for over 9,000 years to make leavened bread, ferment alcoholic beverages, and as an excellent nutritional source. It is even the official state microbe of Oregon.


Sidero owns and develops the patented Siderosorb™ technology platform utilizing Baker’s Yeast, Saccharomyces cerevisiae, to deliver therapeutic proteins/complexes directly to the gastrointestinal tract in order to ameliorate human disease.  Nutritional yeast contains all nine essential amino acids and is consumed by most world cultures, most popularly known as Vegemite in Australia.  Nutritional yeast, the Siderosorb™ delivery mechanism, is generally regarded as safe, affordable, and is readily accepted worldwide.

Yeast is a microbe that is also widely used as a molecular genetic research tool based on its many attributes including:

  • S. cerevisiae is a microbe that replicates very quickly (about 90 min/cell division)
  • It is eukaryotic with cellular physiology more similar to mammals than to bacteria
  • Its genome has been completely sequenced
  • A majority of yeast genes have human similarities
  • ​Its genome is readily manipulated, including insertion of human genes for expression
  • It can grow in either a haploid or diploid state expanding its genetic manipulation capabilities
  • S. cerevisiae is not pathogenic
  • Nutritional yeast is consumed by most cultures around the world
