A study on the ability of some fungi isolated from oil soil contaminated to biodegradation plastic and paper waste in Kirkuk city
Summary
Researchers evaluated the capacity of fungi isolated from oil-contaminated soil in Kirkuk City, Iraq to biodegrade plastic and paper waste under laboratory conditions, testing fungal isolates on different substrate types over defined incubation periods. The study identified several fungal species with measurable plastic-degrading activity, contributing to knowledge of soil microbial biodegradation potential in petroleum-contaminated environments.
This study was carried out in department of life science at the University of Kirkuk, College of Education for Pure Science laboratories to determine the capability of some types of fungi isolated from oil soil contaminated samples taken from different areas of Kirkuk city and to evaluate the biodegradation effect of plastics and papers wastes. The results showed that after taking 50 oil soil samples, the following fungi were isolated: The molds found were Aspergillus spp, Penicillum spp and Alternaria spp. Their impact on seven categories of waste was assessed as the weight was determined for each piece. The overall effect from the project was the reduction on the weight, Among the fungi, Alternaria spp outperformed Aspergillus spp, Penicillum spp and the wastes that lost the most weight after the fungi grew on them were cardboard, coffee cup, and drawing paper.
