title: [Gum-like exudate from Laguncularia racemosa (white mangrove) as culture media for fungi].
abstract: Morphological studies of eight species of fungus: Aspergillus flavus Microsporum canis, Epidermophyton floccosum, Curvularia lunata, Cladosporium carrionii, Natrassia mangífera (Edo. Scytalidium), Sporotrix schenckii y Rhizophus oligosporus, which belong to families Mucedinaceae, Dematiaceae and Mucoraceae have been carried out in support medium based in gum exudate from Laguncularia racemosa (mangle blanco). This native polimer contains galactose, arabinose, rhamnose, uronic acid and proteins. Nitrogen calcium and magnesium are microconstituents of the gum. An economical substrate which contained gum exudate (4%) and agar (1.5%) was used in these studies. The results obtained showed that gum exudate-agar medium (EGA) permits an adequate identification of the studied species, therefore, it is a possible substitute for Sabouraud. It is important to know that the gum exudate is a natural product, economical and easy to obtain.
