Abstract

Glyphosate is an organophosphate compound used as herbicide in agricultural farms. It partly contributes to xenobiotic contamination of soil samples. Issues of toxicity and persistence have given rise to the need for its control in soils. The present study sought to bio remediate glyphosate soil contamination using fungal cultures. Fungal isolates were obtained from glyphosate polluted soil and were screened for glyphosate utilization capacity. Isolates were identified using microscopy and molecular typing of the sequenced ITS region. The best two degraders were made choice isolates used for the bioremediation study. They were used singly and in consortium for the bioremediation process monitored over a four week period. Isolates obtained from the polluted soil sample are Aspergillus niger, Aspergillus terreus, Aspergillus tamari, Fusarium oxysporium and Aspergillus flavus. Aspergillus terreus and Fusarium oxysporium were the best glyphosate degraders and gave residual glyphosate values of 21.17 ug ml and 17.22 ug ml respectively. Their bi culture degradation gave a residual glyphosate value of 8.87 ug ml with 91.41 degradation. This study thus shows that glyphosate soil pollution can be controlled with fungal cultures and can thus be said to be amenable to bioremediation process. Orji, M. U. | Agu, K. C. | Ikele, M.
