Etude synergique du couplage du Système Lactoperoxydase avec d’autres molécules naturelles actives ayant des propriétés antifongiques pour l’amélioration de la conservation en frais des bananes

Abstract : Postharvest diseases are a major concern for several plant products, leading to considerable postharvest losses. Colletotrichum musae is responsible for anthracnose and is also involved in crown rot, the two main postharvest diseases of bananas. The use of natural anti-microbial agents such as the lactoperoxidase system (LPS) represents an interesting alternative to the use of fungicides for the control of postharvest diseases of bananas. This study consisted on optimization of the LPS by adding iodide or substituting the thiocyanate by iodide. Moreover, other substances like lactoferrin, Bioxeda® and Neem oil were analyzed for their antifungal effect. The last two compounds gave an inhibition higher than 90% and 40% respectively. No effect of lactoferrin was observed
