The development of fungi in stored grains present a health risk to customers due to their ability to produce and accumulate mycotoxins. Then, chemical antifungal agents are applied to grains to reduce their contamination by molds. The aim of the present study was to evaluate the antifungal potency of oregano essential oil and thymol on some species of fungi involved in corn spoilage. Molds were isolated, and then identified by their macroscopic and microscopic characteristics after cultivation on standard media. The antifungal activity of oregano essential oil and tymol was conducted by broth dilution method. The mold species isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Fusarium sp., and Mucor sp. Oregano essential oil and thymol demonstrate an antifungal effect against all these isolates. These compounds may be useful as alternative in limiting or preventing the development of harmful fungi and mycotoxins in food.
The main objective of this study is to qualitatively evaluate the degree of implementation of actions and educational activities for health facilities in the F
Discharges from dairies are very rich in organic matter. 900 m3/d of liquid waste is discharged daily by the milk processing unit of the City Rabat / Sal
The lactose in cheese whey is an interesting substrate for the production of bulk commodities such as bio-ethanol, due to the large amounts of whey surplus generated globally. In the present context of increasing demand for energy and biofuel, the microbial synthesis of ethanol using industry waste materials has gained recent importance. The present study deals with the ethanol production from whey-a dairy waste by using potential thermotolerant immobilized yeasts isolates in free and immobilized state. Two species of thermotolerant yeasts strains, Candida inconspicua, Candida xylopsoci and standard culture of K. marxianus were used for bioethanol production. Of the selected thermotolerant yeast species, Candida inconspicua W16 exhibited the maximum production of ethanol (3,9
