The fatty acid composition of phospholipids was studied in different actinomycetes growing in two media in order to detect their biological activity. The total phospholipids of the actinomycetes did not differ qualitatively and their composition was represented by the same series of fatty acids (C13--C19). The qualitative composition and the quantitative content of fatty acids in phospholipids depended on the composition of the growth medium. When the actinomycetes were cultivated in a complex medium, the proportion between fatty acids (C14:0, C14:1, C16:0, C17:0, C17:1, C18:1, C18:2) changed. The qualitative composition of fatty acids in phospholipids varied among the cultures. However, the content of palmitoleic, palmitic and oleic acids was elevated in all of the cultures. Under the given experimental conditions, the actinomycetes were found to synthesize phospholipids containing fatty acids with a high degree of unsaturation (mainly at the account of C16:1 and C18:1 acids).

UI MeSH Term Description Entries
D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system. Phosphatides,Phospholipid
D002621 Chemistry A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D005227 Fatty Acids Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED).

D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D013302 Streptomyces A genus of bacteria that form a nonfragmented aerial mycelium. Many species have been identified with some being pathogenic. This genus is responsible for producing a majority of the ANTI-BACTERIAL AGENTS of practical value.
D013305 Streptomyces griseus An actinomycete from which the antibiotics STREPTOMYCIN, grisein, and CANDICIDIN are obtained.
