[Effect of carbon and nitrogen sources on the deoxyribonuclease activity of actinomycetes (author's transl)].

The amount of the deoxyribonucleases produced by several Actinomyces species in a fluid medium varies considerably, depending on the type of the carbon and nitrogen sources added to the medium. Starch effects the enzyme biosynthesis most favourably of all tested carbon sources. The nitrates are more suitable as nitrogen sources than the ammonia compounds. Highest biosynthesis of deoxyribonucleases is observed on media containing organic nitrogen. Nutrient medium of optimum content may be found for each producer, ensuring maximum biosynthesis of deoxyribonucleases.
