Effect of various nitrate salts on the cordycepin (a) and adenosine (b) production of C. militaris-fermented oats in solid culture. The 30X concentration of Mg2+, Na+, K+, Ca2+, Fe2+ in Mg(NO3)2, NaNO3, KNO3, Ca(NO3)2, Fe(NO3)2·6H2O were equal to that in 30X-DOW. Data are presented as mean ± SD (n = 3). *, **, *** indicated the significant difference (p < 0.05, p < 0.01, p < 0.001, respectively) as compared with UPW.
