ABSTRACT
The present study is to isolate fungi from rhizosphere of Moringa oleifera and screen them for the production of some very important enzymes such as amylase and protease. Twenty fungi were isolated from the soil sample from five different farms using pour plate method. The isolates were then identified based on their colonial morphology and microscopic features in wet mount and Lactophenol Cotton Blue staining. All the isolates were screened for amylase and protease production by starch agar plate method and casein agar plate method respectively. A total of seven isolates were identified up to the species level, while thirteen isolates were identified up to the genus level. The isolate MCS 16 having the highest amylase and protease ability was identified as Aspergillus spp 3. Aspergillus nidulans, Aspergillus niger, Aspergillus terreus Penicillium spp 1, Aspergillus fumigatus, Alternaria spp 1, Rhizopus spp 1, Rhizopus stolonifer, and Aspergillus spp 5, were found in all the five farms where the soil sample were collected with a frequency rate of 25%. The study revealed that rhizosphere of Moringa oleifera can be a very good source of fungi capable of producing enzymes
