Abstract:

Cations are essential to living organisms. Their importance is evident by the diversity of their functions and by the large expenditure of energy needed to drive their transport (Slayman, 1985). K is the major monovalent cation, osmotically active cation, and cellular electrolyte (Hutner, 1972; Eddy, 1958). In fungi and yeasts, K often functions in the transport of divalent cations (Eddy, 1978), sugars (Slayman and Slayman, 1974; Allayway and Jennings, 1970), amino acids (Seaston et al., 1973) and water (Jones and pollard, 1983). The major divalent cation in living organisms is Mg . Like many other cations (e.g. Ca, Mn, Zn, Fe and Cu), Mg generally functions as an enzyme co-factor. Ca typically has important regulatory roles in eukaryotes (Rasmussen, 1970; Carafoli and Crompton, 1978; Pitt and Ugalde, 1984; Veigl et al., 1984). However, relatively little is known about the effect of these important cations on the growth and development of commercially-important fungi.
