Summary

The effect of addition of varying concentrations of certain inorganic compounds in selected media upon growth and pigment elaboration ofEidamella deflexa (Berk.)Benjamin was studied in submerged culture. Preliminary experiments were performed to establish approximate optimum ranges of certain inorganic compounds. Further investigations in a glycine-sucrose basal medium indicated that the following range of concentrations stimulated growth to the greatest extent: 0.2% MgSO4·7H2O, 0.2% K2HPO4, 0.25 mg% CuSO4·5H2O, 0,0% ZnSO4·7H2O and 10.0 mg % FeSO4·7H2O. The degree of pigment production did not seem to be affected by different concentrations of these compounds.

The effects of additional molybdenum and zinc upon growth and pigmentation were studied in the following media: lactose-peptone, lactose-glycine, maltose-peptone and maltose-glycine. Molybdenum increased pigmentation slightly in maltose-glycine and maltose-peptone media, but inhibited the amount of growth. Molybdenum decreased both growth and pigmentation in the two lactose media. Zinc had little affect on either growth or pigment elaboration in the two maltose media. However, in the lactose-glycine medium, zinc decreased both growth and pigmentation while in lactose-peptone media zinc slightly increased growth and pigmentation.
