[Determination of the biological activity of heliomycin by a method of diffusion in agar].
A biological method for determination of geliomycin activity using agar diffusion is described. A nutrient medium containing Hottinger broth up to 35 mg per cent of amine nitrogen, 1.5 percent of agar-agar, tap water, pH 7.8 to 8.0 was used. Bacillus subtilis ATCC 6633 served as the test-culture. Geliomycin was dissolved in 0.1 N sodium hydroxide solution.
