It is shown that nanoparticles have an antimicrobial effect against test microorganisms at a concentration of 5 mg/l. Based on rhamnolipids, glycans and methylthiosulfanilate, liposomal preparations with activity against the tobacco mosaic virus have been created. It was established that liposomes at concentrations of 10 and 100 μg/ml are capable of inducing plant resistance to viral infection and eliminating viral diseases. The possibility of using trehalolipid biosurfactants (1-3 mg/l) for wastewater treatment during the increase of Daphnia magna biomass is shown. A method of obtaining a cellular polymer of polyhydroxybutyrate using a solution of trehalolipid biosurfactants in combination with ultrasonic treatment, heating and washing is proposed. The highest yield of polyhydroxybutyrate (97%) was recorded at a concentration of trehalolipids of 0.15%, a temperature of 40°C, 15 min and ultrasound treatment. The possibility of using sulfur-containing limestone substrates of Rozdilskyi DHHP "SIRKA" for agricultural use with proper correction is shown.
