Defining how microorganisms benefit human health

Abstract

An appreciation for how microorganisms can benefit human health has grown over the past century. The future of this research will be to identify the specific microbial enzymatic pathways and molecules necessary for health promotion. Some of these ‘beneficial factors’ are already known for probiotics and species in the human microbiome, however, precise descriptions of the mechanistic details for their effects remain to be discovered. The need for this research is elevated by the potential use of microorganisms for preventing and treating the non-communicable diseases which are now the leading causes of death worldwide.
