Abstract
Seven composted heaps in addition to the control heap (without microbiological inoculation) were inoculated with six highly ligno-cellulolytic microorganisms singly or in mixed forms as accelerators of the decomposition process for 60 days until compost maturity at room temperature. Throughout composting process at different interval periods (15, 30, 45 & 60 days), mycological survey was performed to select the most effective composts for research continuation. Nineteen fungal species belonging to 9 genera plus to one sterile mycelia were isolated from composted heaps on Czapek’s-dextrose and potato-dextrose agar media using dilution-plate method accounting collectively 1696 x 104 cfu/g.The total fungal count of all treatments ranged between 113 – 545 x 104 cfu/g and it increased with microbial inoculation. Aspergillus, Penicillium and Fusarium were the most prevalent genera in composting process. A. niger,A. fumigatus and P. chrysogenum were the most predominant species. Mucor racemosus, Fusarium solani, A. terreus,A. flavus,Emericella nidulans, A. foetidus,A. subsessils and F. incarnatum were isolated in moderate frequencies of occurrence. While, Trichoderma hamatum,P. brevicompactum, A. sydowii, A. ochraceous, and Saccharomyces cervisiae were isolated in low frequencies of occurrence.
