Abstract
Abstract A selective enrichment nutrient medium for the isolation, identification and propagation of yeasts and fungi containing a fruit pulp, or quinone derivative/s, source of nitrogen, minerals and sugar, where the resulting nutrient medium is useful for the preferential cultivation of molds, yeasts and fungi in the presence of bacteria which will not propagate in the medium.
