| Abstract: | In the studies the protoplasts of the original strain, Streptomyces aureofaciens, were treated by Ultraviolet. Then the author selected single one of each clonies, which were formed by the regeneration of the protoplasts, to check their yield. A high-yield strain was obtained. Contract with the original strain, its product was improved by 28%. |
