    Notes: Summary Nitrosourea induced tumors of the nervous system in rats have proven useful for biochemical studies combined with morphological approaches. The pattern of enzyme activities for acid hydrolases and cytochrome oxidase resemble those previously observed in spontaneous nervous system tumors of man. The activities of 4 acid hydrolases were generally high in the gliomas. This could not be attributed solely to zones of regression or necrosis but was a general characteristic of the neoplasms. The activities were predominantly particulate and most likely lysosomal in localization. In schwannomas a similar increase in hydrolases was found in comparison with normal neural tissues but aryl-sulfatase was not increased. Cytochrome oxidase activities were markedly reduced in all tumors studied. The proportionate reduction with respect to normal brain was comparable to that noted in man. No differences were found with respect to fairly well differentiated gliomas.

    Candida amapae, a new amino acid-requiring yeast from the Amazonian fruitParahancornia amapa (1995)
    Springer
    Journal of industrial microbiology and biotechnology 14 (1995), S. 531-535

    ISSN: 1476-5535
    Keywords: Methionine auxotrophy ; Amazonian fruit ; Candida amapae

    Notes: Summary A new species of oligotrophie, methionine-or cysteine-requiring yeast was isolated from ripening fruits of the AmazonianParahancornia amapa tree. This species resemblesCandida sorboxylosa and species ofIssatchenkia but is nonfermentative and forms abundant pseudomycelia. The new species was isolated only fromP. amapa fruits, and not from other fruits or the drosophilid vectors of the yeast community of the deteriorating fruit. The taxon is regarded as indigenous to the amapa fruit or inoculated by vectors other thanDrosophila before ripening. A description of the new speciesCandida amapae is given.
