Rhizospheric Bacteria, Destructors of Toxic Aromatic Compounds

Abstract

Bacteria capable of degradation of a number of toxic organic compounds (aromatic hydrocarbons, n-alkanes, phenol and its chlorinated derivatives) were isolated from the rhizosphere of plants growing on “clean” and oil-contaminated soil. The most active strain, Lysinibacillus sp. Fg1 was able to utilize more than 15 individual substrates. Six bacterial strains of the genus Pseudomonas decomposed polycyclic aromatic hydrocarbons, suppressed the growth of phytopathogenic fungi and bacteria, and synthesized phytohormones auxins. Keywords—bacteria-destructors, rhizospheric microorganisms, polycyclic aromatic hydrocarbons, phenol,
