To develop new approaches to the isolation of microbial metabolites (cellular and extracellular polymers and surfactants) for low-waste technologies for the production of environmentally friendly products with multifunctional properties, to assess their practical potential
popup.description2
New microbial surfactants were isolated from bacteria isolated from various natural conditions. The lipid composition of bacteria isolated from Antarctic soil includes glycolipids (trehalose mono- and -dimycolates, trehalose mono- and -diacylates) and non-polar lipids. Bacterial strains isolated from oil-contaminated soil synthesized glycolipids (rhamnolipids) and peptidolipids. New peptidolipid and glycolipid biosurfactants synthesized by bacteria isolated from plastic pollution biofilms were isolated and studied. The biodegradation of polyethylene films after wetting with rhamnolipids and TWEEN-80 in flasks and in a composter was studied. The biodegradation of biopolymer films of polylactide, polyhydroxybutyrate and their mixtures was studied. After 3 months, the weight loss of the biofilm based on polyhydroxybutyrate was 52% by strain K2 and 33% by strain K4. The film based on a mixture of polyhydroxybutyrate and polylactide was degraded by 27% (K2, U5) and 39% (U1). Films consisting of polylactide practically did not degrade for 3 months. Filaments from mixtures of polyhydroxybutyrate, polylactide, chitosan and hydroxyapatite were obtained and their physicochemical, mechanical and thermal properties were established. A two-stage technology for the purification of water contaminated with heavy metals using spirulina and trehalosolipids was developed. A solution for wetting and settling Latelux dental composite dust and dentin based on cocoglucoside, decylglucoside and rhamnolipids was proposed. It has been shown that the use of biosurfactants, microbial preparations and sorbents stimulate growth and improve the adaptive capacity of selected plants when grown on oil-contaminated soils. It has been found that the developed remediation complexes can be effectively used in biotechnological approaches to the restoration of territories with a high level of technogenic load, in particular after technogenic accidents, as well as those damaged as a result of hostilities.
