摘要
Some functional interrelationships have been established between yeasts and the soil diplopods Pachyiulus flavipes C. L. Koch and Glomeris connexa C. L. Koch. Yeasts can serve as a food for diplopods when these animals are feeding on leaf litter. The digestion of yeast cells takes place mainly in the midgut as a result of enzymatic activity of the gut fluid. The midgut is a well-protected zone in which enzymatic activity prevents exogenic infection and thereby provides a steady-state environment for the yeast community. The hindgut is a region where specific yeasts can utilize readily-available carbon sources from leaf litter and hydrolyze uric acid-the end-product of nitrogen metabolism of the host animals. A model for yeast distribution in the gut of diplopods is described.
