In this study, soil samples from different areas of Mosul, Iraq, were examined by morphological and molecular methods. Fungi were isolated and grown in diagnostic culture media, including Czapek Yeast Extract Agar, Malt Extract Agar, and 25% Glycerol nitrate agar at different temperatures of 15, 20, 25, and 30°C. The growth rate of the fungus was also evaluated in the culture containing K2HPO4. In the molecular method, the obtained fragment was sequenced using the Internal Transcribed Spacer region primers after replication. Morphological evaluation of both macroscopic and microscopic features revealed that strains were Penicillium rubens, and molecular methods used have confirmed the isolated strain. The results of this study showed a decrease in the diameters of the colonies at different growth temperatures when doubling the amount of K2HPO4. In addition, the findings revealed that compared to growth inhibition in the control groups, the maximum growth inhibition was 16 and 29 mm on Czapek Dox Agar (modified) medium at incubation temperatures of 20°C and 25°C, respectively. As a result, K2HPO4 has an important role in inhibiting growth; therefore, it can be used as Fungicide.}, keywords = {ITS regions,K2HPO4,Penicillium rubens,Morphological characters}, url = {https://archrazi.areeo.ac.ir/article_125418.html}, eprint = {https://archrazi.areeo.ac.ir/article_125418_ceb13cd76f213eff094c97868d47f279.pdf} }
