ABSTRACT

Background:  Crude oil contains heavy metals together with other chemical components, which may adversely affect plant growth as well as pose serious risks to human health when the products from such plants are consumed. Objectives: This study was designed to evaluate the growth performance of Abelmoschus esculentus and iron, lead, zinc, copper and manganese contents of crude oil pollution and bioremediation treatments using Pleurotus ostreatus. Methods:
Ten grams (10g) grams of fungal inocula of P. ostreatus were aseptically weighed and transferred into the already sterilized bottles containing the crude oil contaminated soil and sawdust substrate for the mushroom. The cultures were incubated at 250C for three months. The following treatments were used for this study: Control-0ml (soil only), Pollution treatment (Soil + each concentration of crude oil - 5, 10, 15, 20, and 30mls, respectively), and Bioremediation treatment (Soil + each concentration of crude oil-5, 10, 15, 20, and 30mls + spawns of P. ostreatus, respectively). The physico-chemical parameters of crude oil polluted spawn were determined before and after harvest using standard methods. The experimental set up was maintained for germination and growth studies of Abelmoschus esculentus. Results: There were marked variations (P < 0.05) in iron, lead, zinc, copper and manganese contents of crude oil pollution and bioremediation treatments before and after harvest.  During harvest, the plant height, root length, fresh weight, dry weight, leaf area and fruit number of the plants in bioremediation treatment with P. ostreatus recorded higher values than those of the pollution treatment. Conclusions: This study clearly indicates that P. ostreatus can grow optimally as well as detoxify contaminants in crude oil polluted soil, hence improving the soil conditions for the growth of A. esculentus.
