Comparative study of the influence of γ-, UV- and combined irradiation on streptomyces canosus 71 growth and lipids synthesis

摘要

The morphological mutation of the museum strain Streptomyces canosus 71, its variants obtained under the influence of γ- and UV-rays and new variants selected after the combined irradiation was studied. The lipids quality of Streptomyces canosus 71 and new variants is identical. The quantity of steroids in new variants is increased to 174,7 and 201.0% to control. The unsaturated fatty acid□s, such as C15:1, C16:1, C18:1 predominated in lipids of new variants. Te possibility of application the combined irradiation for Te possibility of application the combined irradiation for obtaining the new Streptomycetes strains, producing the biologically active substances (phospholipids, steroids, unsaturated fatty acids) was shown.
