Abstract

The increase of Mg2+, from 1.3 to 3 mu M, in growth medium of F. equiseti and F. acuminatum increased intracellular magnesium levels from 0.83 and 0.81 mu M to 1.75 and 1.42 mu M on the 12th day, respectively. Intracellular magnesium levels also elevated depending upon the number of incubation days. The maximum manganese levels of F. equiseti and F. acuminatum obtained in 1.6 mu M Mg2+ culture medium were 0.67 and 1.23 mu M, while maximum iron levels were determined to be 1.3 mu M Mg2+ as 0.51 and 0.29 mu M, respectively.
