    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: Summary Nitrogen and sulphur requirements ofColletotrichum inamdarii Lal isolated from the leaves ofCarissa carandas L. have been studied. DL-serine, L-asparagine and L-phenylalanine have been found to be of good nitrogen source followed by potassium nitrate, calcium nitrate, magnesium nitrate, DL-alanine, ammonium nitrate, glutamic acid, ammonium sulphate, DL-valine, aspartic acid, ammonium chloride, ammonium hydrogencarbonate, L-histidine and potassium nitrite. There was no growth in the absence of nitrogen. Sporulation was excellent on calcium nitrate and sodium nitrate, Very good on DL-serine, potassium nitrate, and magnesium nitrate. Good on L-asparagine, L-phenylalanine and ammonium oxalate. Fair on DL-alanine, DL-leucine, ammonium sulphate, DL-valine, ammonium chloride and L-histidine whereas poor on glutamic acid, aspartic acid, ammonium tartarate and ammonium nitrate. Few spores were observed on ammonium hydrogencarbonate but potassium nitrite did not show any sporulation. Amongst the sulphur compounds sodium bisulphate gave the best growth and good sporulation, followed by sodium thiosulphate, magnesium sulphate, ammonium sulphate and potassium sulphate. Thiourea gave negligible growth whereas it failed to grow on zinc sulphate and potassium persulphate.

    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.

    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 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.

    Purification and partial characterization of two extracellular keratinases of Scopulariopsis brevicaulis (1992)

    Notes: Abstract Two extracellular keratinases of Scopulariopsis brevicaulis were purified and partially characterized. The enzymes were isolated by the techniques of gel filtration chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). These keratinases (K I & K II) were purified approximately 33 and 29 fold, respectively. SDS-PAGE of the products of gel filtration chromatography (K I & II) produced only one band each, suggesting homogeneity. The optimum pH for both keratinases was 7.8, while the optimum temperatures were 40°C (K I) and 35°C (K II). Estimated molecular weights were 40–45 KDa and 24–29 KDa for K I & K II respectively. Both keratinases were inhibited by phenylmethylsulfonyl fluoride which suggests a serine residue at or near an active site.

    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.
