Chapter 1 - authors engineered Escherichia coli strains overproducing recombinant enzymes. Chapter 2 - the sp-2 protein possessing anti-tumor activity from soybean cake was examined. Chapter 3 - analyses of lipid peroxidation demonstrate the absence of authentic pathological changes and their manifestations upon introduction of phytohormone epibrassinolide. Chapter 4 - the practice of lavage and perfusion of wounds and cavities by oxygenated solutions in surgical patients during the early post-operation period for the prevention and treatment of complications. Chapter 5 - the authors discuss a peculiar method for immobilisation of the whole non-growing micro-organisms by entrapment of microbial biomass into silica xerogel. Chapter 6 - the development of ß-galactosidase immobilisation on the basis of organosilicone templates with a method of a porous structure formation to product stable preparations with high percent of activity preservation. Chapter 7 - glycolysis was investigated as a source of energy for microbiological synthesis of nucleosidephosphates (ATP,GTP). Chapter 8 - employment of two independent approaches revealed that O-palmitoyl-L-malate does not penetrate through plasma membrane of Saccharomyces cerevisiae cells. Chapter 9 - the condition required to receive stable and highly active heterogeneous biocatalysts for the industrial manufacture of functional nutrition products and pharmaceutical preparations. In Chapter 10 - the authors studied thermodynamic aspects of influence of one of the homologues on the conformational stability of lysozyme while in storage of their combined solutions. Chapter 11 - the ultrasonic low-frequency extraction and basic physicochemical properties of flax seed polysaccharides are presented. Chapter 12 - the antioxidant activity of a number of medicinal, synthesised preparations, BAAs and medicinal herbs intended for prophylactic and treatment of illnesses of the cardiac-vascular system, motor organs and digestion tract are evaluated. Chapter 13 - it was shown that the influence of EHF-radiation on spores of microscopic fungi can cause their destruction, while at the same time, vegetative fungi mycelium is not sensible to the influence of this kind of radiation. Chapter 14 - callus induction in the medicinal plants are discussed. Chapter 15 - developed biotechnologies of gonads and germ cell cryoconservation of commercially valuable fish species of the Volga-Caspian basin for the purpose of their genetic preservation are evaluated. Chapter 16 - a combined EOR method is explored, which integrates total effect resulting from oil-washing capacity of surfactant- based systems and activated hydrocarbon-oxidising reservoir microflora. Chapter 17 - Stimulating effect of polyethylene photoluminescence films on the growth of autochthonous microflora population are examined in oil-polluted soils.
