Efficiency of phenol-containing water purification by immobilized destructive bacteria
(Одеський національний університет імені І. І. Мечникова, 2020) Horshkova, Olena H.; Горшкова, Олена Георгіївна; Горшкова, Елена Георгиевна; Poshelyuk, A.; Radysh, N.; Gudzenko, Tetiana V.; Гудзенко, Тетяна Василівна; Гудзенко, Татьяна Васильевна
As a result of screening evaluation of phenolic oxidative activity of 4 strains of bacteria isolated from pharmaceutical wastewater, the most biochemically active strain of Bacillus subtilis 13 was selected, which after 6–13 days utilized 78–97 % of phenol (phenol concentration in water decreased from 200 mg / l to 6 ± 2 mg / l). Among the 7 studied carriers of different origins, activated carbon, peat and a synthetic carrier of the «VIIA» type had sorption activity against phenol. Immobilization of Вasillus subtilis 13 bacteria on sorbent carriers led to increased efficiency and acceleration of the process of water purification from phenol, while desorption of the pollutant did not occur.
