Title: Evaluation of methods for screening of extracellular cellulase In filamentous fungi
Author: Khiyami, M. A. [محمد احمد خيمي]
Abstract: Twenty-eight fungal species belonging to fifteen genera were isolated from Saudi Arabian soil and were screened for the production of extracellular cellulase enzymes. Cleared-zone technique, cellulose azure method and agar diffusion test for rapid screening were used. The cleared-zone technique was found to be much less reliable as compared to other methods. Trichoderma viride, T. pseudokoningii and Aspergillus fumigatus were the best producers of cellulase enzyme. The data obtained also suggest that caution is needed using these methods. The disadvantages of using one method for screening, which has been a common practise up to now, are discussed.من الواضح أن العديد من الكائنات الحية الدقيقة قالمحرة على إنتاج الأنلإيخمات اللسليلوزية خارج الخلوية. ومن أهمها الفطريات الخيطية المحللة للمخلفات السليلون ية بفعالية أكبر وذلك من خحل معدلاتها الأيضية النشطة. وتعتبر الأنواع التابعة لجنس .
