    Notes: Abstract Twenty-six different species of keratinophilic fungi were examined to determine their ability to utilize free cystine. Of the fungi tested, the majority metabolized free L-cystine in a glucose-peptone culture medium. Cystine was used as source of sulfur, and carbon and nitrogen as well. Excess sulfur was excreted into the culture fluid, as thiosulfate and sulfate, following oxidation. The rate of cystine oxidation varied with the different fungal strains, but was maximal for Graphium penicilloideus (88.5%). Low quantities of thiols were found in the medium. Cystine oxidation and inorganic thiosulfate excretion were found to correlate significantly (r = 0.94).

    Keratin degradation by fungi isolated from the grounds of a gelatin factory in Jabalpur, India (1991)
    Springer
    Mycopathologia 114 (1991), S. 83-87 
    Details
    ISSN: 1573-0832
    Keywords: Fungi ; keratin degradation ; sulfhydryl compounds ; sulfate ; thiosulfate ; keratinase

    Topics: Biology , Medicine
    Notes: Abstract The ability of five keratinophilic fungi, i.e., Chrysosporium indicum, Geotrichum candidum, Gymnoascoideus petalosporus, Scopulariopsis brevicaulis, and Talaromyces trachyspermus, to digest human hair keratin in stationary culture has been studied. Degradation of human scalp hair was studied by determination of cysteine, cystine, inorganic sulfate, thiosulfate, total protein, keratinase and change in alkalinity of culture filtrate. Gymnoascoideus petalosporus showed maximum degradation as compared to remaining isolates when grown on human scalp hair as the sole source of nutrients ‘in vitro’.
