    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).

    Description / Table of Contents: Zusammenfassung Die Wirkung von verschiedenen Kohlenhydratquellen an Zuckerkonzentration und Zusammensetzung des Myzels ofAspergillus niger war untersucht an verschiedenen Tagen der Inkubation. Keine positive Korrelation konnte festgestellt werden unter Trockengewicht, Wachstumsrate, Zuckerkonzentration, Nährboden und Zuckerbildung des Myzels. Glukose war der vorherrschende Zucker in allen Fällen.
    Notes: Abstract The effect of different carbon sources on the sugar concentration and composition of theAspergillus niger mycelium has been studied at different days of incubation. No positive correlation could be drawn among dry weight, growth rate, and concentration of sugar and with substrate and sugar composition of mycelium. Glucose was the predominant sugar in all the cases.

    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’.

    Notes: Abstract Chrysosporium queenslandicum, Graphium penicilloideus andScopulariopsis brevicaulis were grown on various supplemented basal salts media to compare keratinase induction, activity and repression. All three fungi can utilize keratin as a sole source of carbon, nitrogen and sulfur. Total keratinase activity inC. queenslandicum andS. brevicaulis, was not repressed by supplementation of keratin-containing medium with glucose, ammonium or sulfate. The production of keratinase activity was not derepressible in keratin-free media. Keratin utilization commenced before the detection of significant extracellular keratinase activity which was always associated with mycelial growth.

    Notes: Abstract Absidia cylindrospora and Rhizomucor pusillus, causal agents of phycomycoses, were cultured on sterile natural keratins in a mineral solution and the keratin degradation products analyzed. The excess of sulphur was removed by oxidation to inorganic sulphate and thiosulphate, which were the main products of sulphitolysis of keratin. The proteolytic activity of the two fungi depended on the nature of the keratin substrate. Human scalp hair was the most favoured keratin substrate by both the fungi.

    Notes: Abstract Sulphur requirements ofCurvularia pallescens, Alternaria citri, andA. tenuis have been studied. The fungi exhibited selectivity towards different sulphur compounds. Magnesium sulphate gave best growth and sporulation of the three fungi and it could not be replaced by any other sulphur compound.
