Investigation of black oil and diesel biodegradation in water

Abstract

The effectiveness of biopreparations in destruction of black oil and diesel contaminated water was analysed. The destructive ability of the preparation GVT was compared with that of another biopreparation, K-2000, and of the enzymatic preparation Roebic K-47, as well as of GVT and Roebic K-47 mixture. The prevalence of oil oxidising microorganisms in the case of black oil biodegradation in water was estimated. The biopreparation GVT was the fastest in oil destruction. When water was contaminated with diesel all biopreparations were equally effective.

Tirtas biopreparato GVT efektyvumas valant mazutu ir dyzelinu užterštą vandenį. Preparato galimybė skaidyti teršalus lyginta su biopreparatu K-2000, fermentiniu preparatu Roebic K-47 bei su biopreparato GVT ir fermento Roebic K-47 mišiniu. Nustatyta, kad mazuto biodegradacijos metu bandiniuose naftą oksiduojančių mikroorganizmų buvo daugiausia ir efektyviausias skaidymas – naudojant biopreparatą GVT. Dyzelinu užterštą vandenį visi naudoti preparatai valė iš esmės vienodai efektyviai.
