A method for pre-treatment of wastewater with the simultaneous production of biological surface-active substances (bio-surfactants) by deep cultivation of the microscopic fungus Hypomyces odoratus in the wastewater of a winery has been developed. In wastewater after cultivation of the fungus under aerobic conditions for 12 hours, a steady decrease in BOD was observed by 2.5 times, COD by 3 times, the content of suspended solids, sulfates, phosphates, ammonium ions, nitrates, nitrites, anionic surfactants decreased significantly substances (ACAS), cationic surfactants (CAS), wastewater in chemical composition began to approach the indicators of municipal sewage. The complexity of the composition obtained during the cultivation of the biomass fungus and the isolated exopolysaccharide contributed to a decrease in the surface tension of the oil and indicated that the fungus synthesizes the bio-surfactant complex. After contact with a 12-hour mass of fungus or exopolysaccharide obtained from biomass in highly viscous, water-flooded bituminized oil, an improvement in rheological indices was noted, and the water cut and content of paraffin deposits decreased.

Higher aquatic plants (HAP) provide more effective tertiary wastewater treatment in biological ponds. They also accelerate the clean-up process with simultaneous increase of hydraulic loading. There was observed not only high removal efficiency for domestic organics, but also for various universal pollutants such as oil, synthetic surface active substances and phenols. Our findings have demonstrated that HAP stabilization ponds may be used successfully for industrial waste water treatment. We have also shown it expedient to apply the method in biological, biochemical and vitamin production plants and sugar refineries. HAP of reed, cane and rush proved to be the most effective plants to use.

As a result of the influence of the corrosive environment, the construction materials have a decrease in performance. To increase the service life of the structures, continuous monitoring and, if necessary, restorative repairs are carried out. One of the ways to maintain the initial properties for materials is to give them a self-healing effect by introducing a specially developed additive containing a bioactive component in the manufacturing process. The article presents the results of research on the ability of building materials based on mineral binders to self-repair. Mixtures containing nutrient medium for the biomass of aerobic bacteria were used as bioadditives. Portland cement and gypsum binder were used as mineral binders. The obtained results allow to make a conclusion about a significant change in the rheological properties of cement-sand mortars due to the presence of biological surface-active substances that are part of the cells of microorganisms. The effect of changing the concentration of cells on the setting time and on the strength characteristics of cement-sand mortars was established.

1. The rate of penetration of some representative drugs into Ascaris lumbricoides var. suis has been measured.2. The series of 4-n-alkyl resorcinols shows a typical homologous series effect.3. l-Nicotine penetrates relatively slowly.4. Its rate of penetration is greatly influenced by the extent of dissociation of its methyl pyrrolidine basic group.5. The rate of penetration of nicotine is greatly accelerated in the presence of some surface active substances.6. Chloroform is the most rapidly penetrating substance studied, and its penetration is not significantly influenced by the presence of proteins, carbohydrates and fats and their products of digestion.7. An analysis of the experimental results shows that the outermost layer of the cuticle of Ascaris is probably the main barrier to penetration. It behaves as if it were a thin; homogeneous layer of lipoid.8. The significance of these results in the study of anthelmintics is assessed.
