The plant Aloe vera (aloe barbadensis) leaves were collected from Vimtim area of Mubi North LGA. These plants will be botanically authenticated in the Department of Botany, Adamawa State University Mubi. The leaves were shade dried and used for the extraction. The leaf juice is obtained by grinding or macerating the entire Aloe vera (aloe barbadensis) leaf followed by purification to remove the phenolic compound found in the latex. A standard sample of Aloe vera (aloe barbadensis) gel was extracted by a simple drain procedure where leaves of Aloe were cut at about half an inch from the base so as to drain out all the yellow sap material. The sap flows freely with the presence of epidermal cells and all other cellular structures above it. The Nutrient Agar was prepared according to the manufacturer’s guide. The prepared media will be sterilized by autoclave at 121°C. All glasswares was sterilized by autoclaving at 121°C. SDA– Soubraud dextrose Agar for the culturing of fungi. Table 1 shows that the petroleum ether extract has shown a high zone of inhibition in Escherichia coli, S.aureus, the fungi Aspergillus niger and a moderate zone for Staphylococcus aureus, and A. niger.
