Yeast-form cells of cadmium ion-tolerant Hansenula anomala B-7 were changed to mycelial cells in medium containing more than $400mu$g/ml of cadmium. Moreover, the mycelial cells were exchanged into clumped cells in a medium containing more than $1,000mu$g/ml of cadmium. Optimal conditions of mycelial cell formation were achieved in the presence of .$1,000mu$g/ml of cadmium with shaking cultivation for 7 days. Glucan and mannan contents of the yeast cell wall frown with $1,000mu$g/ml of cadmium decreased by 10% compared with those grown without cadmium. However, protein and lipid contents increased about 20% respectively. By cadmium, no significant findings in specific amino acid contents were discovered.
