CANDIDA-AMAPAE, A NEW AMINO ACID-REQUIRING YEAST FROM THE AMAZONIAN FRUIT PARAHANCORNIA-AMAPA

A new species of oligotrophic, methionine- or cysteine-requiring yeast was isolated from ripening fruits of the Amazonian Parahancornia amap a tree. This species resembles Candida sorboxylosa and species of Issa tchenkia but is nonfermentative and forms abundant pseudomycelia. The new species was isolated only from P. amapa fruits, and not from other fruits or the drosophilid vectors of the yeast community of the deter iorating fruit. The taxon is regarded as indigenous to the amapa fruit or inoculated by vectors other than Drosophila before ripening. A des cription of the new species Candida amapae is given.
