  8. 8. The method of obtaining bioactive substances from arboreal greeneryThe wood and arboreal greenery of such conifersas pine, fir, etc. are an indispensable source ofraw materials for obtaining bioactive substances.The purpose of this work is to study the processof isolating bioactive substances from conifers,as well as to develop a method of obtainingmedical preparations from the components ofarboreal greenery.Two groups of research problems need to besolved in order to accomplish the purpose:-the analytical research to identify individualcomponents of essential oils, polyprenols, resinacids and neutrals that are extracted fromarboreal greenery;- the technological research: selection andoptimization of the way of extracting bioactivesubstances from arboreal greenery,substantiation of the method for separating essential oils, development of theisolation techniques and calculation of the equipment needed.
  9. 9. ECOLOGICAL BIOTECHNOLOGYIsolation and selection of strains of the microorganismsdecomposing polychlorinated biphenylsProduction, in the laboratory amount, of the biomassnecessary for the bioremediation of soils
  10. 10. Isolation and selection of strains of the microorganisms decomposing polychlorinated biphenyls, as well as production, in the laboratory amount, of the biomass necessary for the bioremediation of soilsThe resistant organic pollutants include toxicpolychlorinated dibenzo-para-dioxins, dibenzofurans,pesticides – such as aldrin, heptachlorine, dieldrin,DDT, mirex, toxaphen, chlordane, endrin andhexachlorobenzene, as well as polychlorinatedbiphenyls (PCB). The properties common to all thesecompounds are hydrophobicity, liability toaccumulation in ecosystems, resistance to chemicaland biological transformation, and high toxicity. The work carried out in this area involves:- isolation and species identification of the isolatedstrains of the microorganisms that decompose PCB;- study of the mechanisms of PCB transformation bythe isolated strains;- verification of the possibility to use thesepreparations for decontamination of the soils pollutedwith PCB.
  11. 11. AGRICULTURAL BIOTECHNOLOGYCell selectionMicroclonal reproductionUse of associations between microbes andplants
  12. 12. Cell selectionMajor efforts of the biotech research areconcentrated on creating improved andfundamentally new genotypes of crops thatpossess either singular or combinedresistance to both biotic and abiotic stressfactors of the environment (fungous, viral,bacterial diseases; the acidity and salinity ofsoils, a drought, presence of heavy metals,etc.) while preserving and even increasingtheir productivity and quality.The method consists in introducing the plant into an in vitro culture andselecting the isolated tissues and cells on the growth media that containspecific types of selective agents in various combinations. The most frequentobjects of research are cereal and leguminous crops. The cell selectionreduces the time needed to create new breeds of crops by expanding thegenetic variety when isolated tissues are cultivated in vitro.
  13. 13. Microclonal reproductionThis is a challenging method of the vegetativereproduction of plants that makes it possible to obtaingenetically uniform and sanified planting stock, tohave high net reproduction, to reduce the duration ofthe selection process and to carry out the workthroughout the year, thus saving the areas for growingcrops. The objects of research are fruit, berry andflower crops.The method consists in removing the crown meristemfrom the stem, introducing it into an in vitro cultureand then micrografting the set on a hormonal medium.In order to increase the efficiency of microclonalreproduction, individual cultivation conditions(physical factors and the composition of the medium)should be arranged for each plant species.
  14. 14. Use of associations between microbes and plantsA technology for the combined application of thetraditional methods of tissue culture and the inoculationof plants in vitro is being developed. The positive effectis based on the capacity of some microorganisms thathave a stable association with plants – e.g.,methylobacteria – to synthesize vitamins and hormones(most often, auxins and cytokinins).This makes it possible to use biotechnologicallypromising strains as substitutes for some ingredients ofthe phytohormonal composition of the medium whencultivating isolated cells and tissues. The logicalcontinuation of the research is the creation of abiopreparation of the microbial origin (a growthregulator).
  15. 15. FOOD BIOTECHNOOGYCreation of bioactive food additives Processing both agricultural and recyclable materials to obtain bioactive substances to be used in the food industry Study of physical and chemical properties and structure of biological active substances Designing bioactive food additives obtained from plant materials. The work is under way to obtain bioactive food additives from bilberries (Vaccinium myrtillus L.).Research aimed at extending the range offunctional food products
  16. 16. BIOORGANIC CHEMISTRYStudy of the structural features of pectinpolysaccharides and their biological activityStudy of the biopolymers of themicroorganisms used for creatingpreparations with probiotic properties
  17. 17. Study of the structural features of pectin polysaccharides and their biological activityPectin polysaccharides are capable of a wide range of physiologicalactivities. The antimicrobial, antitumoral, anti-inflammatory, antiulcer andanticoagulant action of pectins is well known. Among the possible ways ofusing pectin substances in medicine is modifying them chemically to createpreparations with specified properties. It was proved, in particular, that anumber of medicines, when combined with pectins, enhance and prolongtheir therapeutic properties, as well as reduce unwanted side effects.The work in this area consists in studyingthe composition of pectin substances in thehips of a number of brier (Rosa) species,their structural features and physiologicalactivities. The pectins in the pap of theRosa rugosa hips were proved to bind low-density lipoproteids in human blood, tomodulate the adhesiveness of peritonealmacrophage in mice and to stimulateformation of serum antibodies (ОВА-IgG-log2) to the protein antigen (OBA) in mice.
  18. 18. Study of the biopolymers of the microorganisms used for creating preparations with probiotic properties - the effect of the medium composition (source of carbohydrates) on the composition, structure and physiological activity of exopolysaccharides of lactic-acid bacteria; - the effect of the medium composition (source of carbohydrates) on the composition, structure and physiological activity of the cytoderm polysaccharides (peptidoglycane) of lactic-acid bacteria;- application of the data on the fatty-acid composition of cytoplasmicmembranes for the species identification of lactic-acid bacteria.
