Abstract

Yeasts and molds isolated from spoiled dried prunes were identified. Sixty-two strains of yeasts included 21 of Saccharomyces rouxii, 11 of S. mellis, eight of Torulopsis magnoliae, five of T. stellata, four of Candida krusei, three of Trichosporon behrendii, two of Pichia fermentans, two of P. membranaefaciens, two of C. chalmersi, and one each of S. rosei, S. cerevisiae, Sporobolomyces roseus, and C. parapsilosis.

One hundred and twenty-four strains of molds which were identified included 56 strains of Aspergillus glaucus, 18 of A. niger, 41 of Penicillium spp., four other Aspergillus spp., two Alternaria, and one each of Monilia sp., Chaetomella sp., and Mucor sp.
