Purification and Chemical Characterization of a Potent Acaricide and a Closely Related Inactive Metabolite Produced by C47.

Mites are arthropods and some of them infest dry meat cured products and produce allergic reactions. Some mites, such as , or feed on filamentous fungi that grow during the meat curing process. Removal of mite infestation of meat products is extremely difficult and there are no adequate miticidal compounds.

Biological control of mites by xerophile Eurotium species isolated from the surface of dry cured ham and dry beef cecina.

Unlabelled: Some meat dry products, including dry cured ham and dry beef cecina, are cured in cellars at moderately cold temperature allowing the growth of a lawn of fungi on their surface. During the curing process, frequently these products became contaminated with fungivore mites of the Acaridae family that feed on fungal mycelium and spores.

Aims: The aim of this article is to study the possible biological control of mites by fungi that form part of the normal microbiota of these meat products.
