Документ Efficiency of purification of water from cyclic aromatic xenobiotics with strains P. fluorescens ONU328 and P. maltophilia ONU329(Одеський національний університет імені І. І. Мечникова, 2018) Horshkova, Olena H.; Voliuvach, Olha V.; Tkachenko, A.; Pihteeva, A.; Smazchuk, O.; Haidarzhi, A.; Волювач, Ольга Вячеславовна; Волювач, Ольга В'ячеславівна; Горшкова, Олена Георгіївна; Горшкова, Елена ГеоргиевнаAbstract. It has been experimentally established that non-pathogenic strains of bacteria of the genus Pseudomonas, identified by the fatty acid composition of their cellular lipids as P. fluorescens ONU328, P. maltophilia ONU329 (isolated from the marine environment), have oxidizing ability for cyclic aromatic xenobiotics (phenol, N-cetylpyridinium bromide). The high phenol-oxidizing ability of the investigated strains of microorganisms is proved. When water of bacterial cells in the amount of 7.5 x 105 CFU/ ml is introduced into phenol contaminated (at a concentration of 300 mg / l), the degree of water purification from phenol is 100% on day 18 when using as a biodestructor strain P. maltophilia ONU329 and 22 days - when using strain P. fluorescens ONU328. It has been experimentally confirmed that when the free cells of bacteria of P. fluorescens ONU328 or P. maltophilia ONU329 strains in the amount of 5.5x104 CFU/ ml are introduced once into the contaminated water, the purification rate of water from N-cetylpyridinium bromide at a concentration of 20 mg / l reaches 50.7% for the 4th day and 55.7% for the 6th day, respectively. With the repeated introduction of fresh portions of microorganism-destructors or use of higher starting doses (5.5x10 CFU/ ml), the water purification rate from N-CPB is 98.0-98.5%.Документ Screening of marine microorganisms resistant toaction of deca (ethylene glycol ) monooctylphenol ether(2017) Horshkova, Olena H.; Gudzenko, Tetiana V.; Smazchuk, O.; Pihteeva, A.; Haidarzhi, A.; Voliuvach, Olha V.; Волювач, Ольга В'ячеславівна; Волювач, Ольга Вячеславовна; Горшкова, Елена Георгиевна; Горшкова, Олена Георгіївна; Гудзенко, Татьяна Васильевна; Гудзенко, Тетяна ВасилівнаSynthetic surfactants are a part of all domestic and most industrial wastewater. 95-98% of the total amount of detergents used in Ukraine are synthetic detergents based on surfactant mixtures, which, as a rule, are characterized by low biological decomposition and because of their chemical nature have a negative impact on water bodiesДокумент The use of wine yeast in the production of red wines in biotechnology(Одеський національний університет імені І. І. Мечникова, 2018) Haidarzhi, A.; Tkachenko, A.; Smazchuk, O.; Pihteeva, A.The experiments conducted indicate that yeast Saccharomyces vini the studied race siha aktivhefe 4 refer to glucosophilic yeasts of the genus Saccharomces, fermenting the most significant fraction of sugar in grape juice. These yeasts end up fermentation, and many of them are involved in the formation of the aroma of young red wines. Yeast assimilate and ferment glucose, galactose, sucrose, maltose and raffinose (by 1/3), do not absorb and do not ferment dextrins, lactose, inulin, xylose, arabinose. Assimilate ethyl alcohol and glycerin, do not assimilate mannitol, dulcite, sorbitol. From organic acids, they absorb acetic and lactic acid, they do not absorb amber, apple, wine and lemon. In winemaking, yeast can play a negative role, causing turbidity of the finished wines.
