| Abstract | Fungi contribute significantly to the recycling of organic waste and the production of green energy, such as bioethanol which can be used as a component in gasoline blends for vehicles and as a standalone fuel in flexible-fuel vehicles. In this study, the capacity of soil fungi which isolated from agricultural soil in Basrah governorate to recycle corn and barley waste into bioethanol was made. Two enzymes (cellulase and ligninase) were used to assess the enzymatic activity of seventeen isolated fungal species. The isolated fungi in this investigation showed adequate activity; nine of them were able to produce the cellulase enzyme, and seven of them were able to produce the ligninase enzyme. The capacity of the fungi to generate bioethanol in liquid media containing glucose was tested. The results demonstrated that two species, Aspergillus flavus and Penicillium sp.1, produced the maximum quantity of bioethanol 4.8 g/L and 3.62 g/L respectively. The ability of Penicillium sp.1 to generate bioethanol from corn and barley wastes was then examined. The highest concentration of bioethanol produced was 1.86 g/L with barley waste after 144 hours of incubation, and 4.26 g/L with corn waste after 96 hours of incubation. Then the effect of the optimum pH and nitrogen conditions on the growth of Pencillium sp.1 and bioethanol production were test. The results showed that the application of optimum conditions improved the production of bioethanol, with the highest bioethanol production being 9.38 g/L after 144 hours with barley, and 6.14 g/L with corn wastes after 48 hours of incubation. |
