The research was conducted to isolate soil fungi and screen them for cellulase production using the zone of hydrolysis technique. Several fungi were isolated and characterised from soil environments of different locations using conventional microbiological methods. A total of six isolates were confirmed to be Penicillium chrysogenum, Emericella rogulosus, Aspergillus terreus, Aspergillus flavus, Aspergillus niger, Aspergillus fumigatus, all coded as BG1, BG2, BG3, BG4, BG5 and BG6, respectively. Fungal isolate BG5 has the highest percentage of occurrence (34.30 %), followed by SBG3 (22.86 %). The isolates were screened for cellulase production using the carboxymethyl cellulose (CMC) agar plate method. All the fungal isolates demonstrated cellulase production ability, with fungal isolates BG5 (18 mm) and BG3 (15 mm) having the highest diameter of zone of cellulose hydrolysis. The research reveals the potentiality of using locally isolated soil fungi for cellulase production.
