Bioremediation of HCB-contaminated soil using Comamonas testosteroni and Zea mays L.

Abstract

Bioremediation measures to restore soil ecosystems are environmentally safe, promising and relevant. Soil ecosystems contaminated with hexachlorobenzene require remediation measures. Studying the effectiveness of applying the microbial remediator Comamonas testosteroni UCM B-400, phytoremediator Zea mays L. cultivar Olena and microbial and phytoremediation complex to remove hexachlorobenzene contamination was carried out. The HCB content was determined by chromatographic method, the microbial groups reactions to application of various remediators in the soil were studied by classical microbiological methods. The results showed that the most effective is the complex using remediators Comamonas testosteroni UCM B-400 and Zea mays L. cultivar Olena, where HCB content was reduced to 82%.
