Abstract
The present investigation aimed to evaluate chitosan, shrimp shell waste and chitin against the fungus activity. Shrimp shell methanolic extract showed stronger inhibitory effects than chitin. Thus, the inhibition zone reached (19.5 mm) for Asprigellus fumigates and reached (16.5 mm) against both Aflavus and A.niger, while the chitosan extract showed the lowest effectiveness. The natural treatments for Candida albicants were not effective. In contrast, Nesoral as chemical product recorded the maximum inhibitory activity for all tested fungi. The antioxidant properties were observed through total polyphenolic compound. The results indicated that chitin, chitosan and shrimp shell exhibited the highest antioxidant properties. The present finding revealed that the tested Chitin, Chitosan and Shrimp shell waste are promised materials from natural sources as antifungal agents.
