description.abstract This study investigated the ability of soil yeasts, Geotrichum candidum, Geotrichum capitatum and Williopsis californica to produce extracellular enzymes (amylase, cellulase and protease) in vitro compared with that of a laboratory strain of Saccharomyces cerevisiae. It appears that the soil yeasts studied here were less amylolytic yeasts except the yeast G. candidum, which was highly effective at extracellular amylase production. The soil yeast W. californica was an average producer of cellulase enzyme. G. capitatum was an excellent proteolytic producer and it was the most active yeast in gelatin hydrolysis. The production of extracellular enzymes by soil yeasts was confirmed by the cleared-zone technique using Czapek-Dox agar medium. en_US
description.abstract معلوم ان الفطريات لها دور مهم في حياة الأنسان من خلال ما تنتجه هذه الكائنات الحية الدقيقة من انزيمات تعمل على تحلل المواد العضوية وأكسدة المعادن في التربة لتصبح متوفرة للنبات . كما تدخل هذه الانزيمات في كثير من الصناعات والتخلص من النفايات ، ويستفاد منها ايضا في النواحي الطبية لخلي مة الإنسان . ar
