【 摘 要 】

Importance of lipids in nature can not be underestimated. It is not only a group of substances which participate in process of metabolism; these substances can be wide using in fields of science and industry. Due to increase cost of animal and vegetal lipids, an alternative can serve microbial lipids. Actinobacteria is the group of microorganisms which is an excellent source of lipids, especially strains of genus Streptomyces. In next research changes of fractional composition of lipids of Streptomyces spp. cultivated on complex media with different nutrients were studied. Streptomyces spp. were isolated from soil samples of Republic of Moldova, cultivation was realized on complex media M-I and R. Maximal quantity of lipids in biomass were obtained after cultivation of strains on medium M-I (12.1-14.3%) and on medium R (12.27-18.69%). The most important fraction as sterols achieved following results: after cultivation on medium M-I it varied between 8.3-14.6% and on medium R – 8.7-10.98%. For fraction of phospholipids were fixed next data: after cultivation on medium M-I, the quantity was 9.1-14.3% and on medium R – 8.7-17.16%. Obtained results show perspective of application of bioproducts based on streptomycetes lipids in agriculture and husbandry due to sufficient quantity of total lipids and some fractions apart.
