Abstract

The ferrichrome content of cells of the smut fungus Ustilago sphaerogena during growth in a medium deficient in zinc increases with increase in the cobalt of the medium from 0 to 3 X 10(-5)M. The addition of zinc to such cultures prevents the accumulation of ferrichrome. The results suggest that zinc is involved in the utilization of iron via a process which can be blocked by cobalt.

摘要

在缺锌培养基中生长时,黑粉菌 Ustilago sphaerogena 细胞中的铁载体含量随着培养基中钴浓度从 0 增加到 3 X 10(-5)M 而增加。向此类培养物中添加锌可防止铁载体的积累。结果表明,锌通过一个可被钴阻断的过程参与铁的利用。
