Abstract
Oil spillage is a serious problem all over the world. Usage of agricultural byproducts for raw materials in biosorbents applications is a promising way to solve this problem. In this paper, a green biotechnological procedure has been developed using Phanerochaete chrysosporium to produce an oil-sorbent from corn stalk and corn cob. Without fungal modification, the maximum sorption of oil by raw corn stalk and corn cob was 6.95 g/g and 4.14 g/g, whereas the treatment with Phanerochaete chrysosporium increased up to 9.03 g/g and 7.69 g/g, respectively. SEM and XRD were applied to characterization of treated and untreated materials, which showed the changes in the surface morphology and crystallinity of all biosorbents. The agricultural by-products can be utilized as biosorbent for efficient oil removal, and fungal treatment can serve as a mild and green method to increase the sorption capacity.
