| Outline of Final Research Achievements |
This study aimed to clarify the whole picture of metabolic systems of oral biofilm through the metabolome analysis and metabolic activity measurement, and to consider an assessment of oral health and disease using oral microbiome metabolism. The CE-MS metabolome system enabled to analyze the metabolites associated with carbohydrates and amino acids comprehensively and revealed the whole picture of metabolic systems of carbohydrates and amino acids in the oral biofilm. In addition, the metabolic activity of a tiny amount of oral biofilm was successfully measured using the alamarblue system. Furthermore, the metabolic activity was diverse among sample sites and metabolic substrates, suggesting that these metabolic characteristics of oral microbiome can be used as an indicator of oral health and disease.
