| Abstract | Yeast-form cells of cadmium ion-tolerant Hansenula anomala B-7 were changed to mycelial cells in medium containing more than 400 ㎍/㎖ of cadmium. Moreover, the mycelial cells were exchanged into clumped cells in a medium containing more than 1,000㎍/㎖ of cadmium. Optimal conditions of mycelial cell formation were achieved in the presence of 1,000 ㎍/㎖ of cadmium with shaking cultivation for 7 days. Glucan and mannan contents of the yeast cell wall frown with 1,000 ㎍/㎖ 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. | ||
