| Outline of Final Research Achievements |
It was revealed that the edible mushrooms, Flammulina veltipes and Pleurotus ostrteatus produce fruit bodies on a sawdust medium supplemented with various kinds of monosaccharides including rare sugars. As a result of having analyzed various kinds of health-promoting activities that each fruit body showed, it was found that immunostimulatory activity of Flammulina veltipes which was cultivated on the medium supplemented with D-allose or allitol (both are rare sugar) was markedly higher than that of Flammulina veltipes cultivated on the medium without the added rare sugars. Such effect was not detected in natural sugars, D-glucose and D-fructose. The analysis of the monosaccharide-converting reactions using vegetative mycelia of the above edible mushrooms demonstrated that these vegetative mycelia have the activity to reduce ketohexoses at C2 position producing hexitols.
