THE ROLE OF GLOMUS MOSSEAE IN THE BIOCHEMICAL RECOMMENDATION OF CONTAMINATED HYDROCARBON (BLACK OIL) SOILS

Abstract

The aim of this study is to determine the ability of the Glomus mosseae in collaboration with the carrot Daucas carota L.in biochemical biodegradation and reduce the proportion of hydrocarbons from contaminated soil, A factorial experiment was carried out in pots with two factors: first use of the inoculum Glomus mosseae gets from the German company Bio-Vita (M1 or M0), second factor using 3 concentration of black oil (0, 1 and 2%) (H0, H1 and H2) and the cultivation of carrot Daucas carota L to recommendation soil contaminated with black oil. The results showed a significant difference in the number of mycorrhiza spores in the soil and the percentage of infected carrot roots with G. mosseae. Significant increase was also found in wet and dry weight of vegetative and root parts at G. mosseae treatment and the addition of black oil at treatment H1. There was also a significant increase in the amount of hydrocarbons absorbed in the root and vegetative of the carrot plant in the inoculum and black oil treatment at the concentration of 2% and the interaction of the treatments was greater than the treatment H2M1 (concentration of 2% with G. mosseae) on other treatments. An acceptable decrease was observed in the amount of residual hydrocarbons in the soil. In the M1 treatment 78.60% and 74.60% for the concentrations of 1% and 2% compared to the treatment M0 (71.40 and 69.70%) respectively, We conclude that the use of carrot and G. mosseae in the removal of black oil compounds from the soil was effective with a concentration of 2%.
