The Relationship between Aspergillus clavatus and Saccharomyces cerevisiae in a Simulation Ecosystem of Koji Making

A simulated system of Koji making which was designed by the authors and researching results of the interaction effect between Aspergillus clavatus and yeast using the system were reported. Results showed that A.clavatus growth could promote yeast growth,while the existence of yeast would inhibit A.clavatus growth and metabolism.
