трегалозоліпіди

Solutions of biologically active substances insoluble in water (thiosulfoesters, anthraquinone derivatives, pyrazoline) were obtained using a combined solvent and biogenic surfactants. For this purpose were used rhamnolipids, their biocomplex with polysaccharides synthesized by the Pseudomonas SP strain. PS-17, trehalosolipids of the Rhodococcus erythropolis AU-1 strain, and the commercial biosurfactant surfactant. Aqueous dispersed systems of the studied substances were also obtained. The research results have prospects for use in pharmacy.

It was established that strain R. erythropolis Au-1 synthesizes cell-associated trehalose lipids (0.4-2.9 g/l) and exopolysaccharides (1.6-8.3 g/l) during the growth on nutrient medium with different carbon sources. After pre-sowing treatment of seed by products of this strain morphometric parameters of wheat, rape and coleseed seedlings, including during the growth on oil-polluted environment were increased on 8.0-110.9 %.
