Titre : Antifungal activities against mould and yeast strains Type de document : texte imprimé Auteurs : Meral Birbir, Auteur ; O. Özyaral, Auteur ; C. Johansson, Auteur ; A. Ilgaz, Auteur Année de publication : 1996 Article en page(s) : p. 114-117 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The efficacy of three commercially available fungicides was determined on 20 fungal species and nine yeast species isolated from Turkish vegetable tanned sole leathers, chrome tanned hides (blue stock), 1-2 years and older chrome tanned leather, new and used shoes, and human feet. Each of the isolated organisms, whether fungi or yeast were treated with a series of dilutions of the fungicides to determine their relative effectiveness.
The active ingredients of the commercially available fungicides were : isotiazoline and a quaternary ammonium compound (Fungicide 1A), benzthiazole (Fungicide B), and p-chloro-m-cresol with o-phenylphenol (Fungicide C). Fungal attack was controlled with fungicide A at a 1:16 dilution, fungicide C were more effective than fungicide B in controlling fungal growth on leather. Fungicide A at 1:128 dilution, fungicide B at 1:64 dilution and fungicide C at 1:128 dilution exerted complete protection against yeast growth.En ligne : https://drive.google.com/file/d/1suUFroIcVc9jJ25z22d1vlsbATbsDtOp/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8122

Titre : Halophilic bacteria isolated from brine cured cattle hides Type de document : texte imprimé Auteurs : Meral Birbir, Auteur ; Waldo E. Kallenberger, Auteur ; A. Ilgaz ; David G. Bailey Année de publication : 1996 Article en page(s) : p. 87-90 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Halophilic and halotolerant organisms found on brine cured were isolated and at least partially characterized. All of the halophilic bacteria isolated from the brine cured cattle hide samples used in these experiments were motile. Gram negative, aerobic and extremely pleomorphic organisms. The colonies formed by these bacteria were either bright pink, red, or purple colonies on media containing 27 %, and 30 % salt. The halotolerant colonies on 20 % salt media were all white. Seventy percent of the isolates showed a positive gelatin test. The effect of the different salt solutions on the pH of brine cured hide sample was examinde. When hide samples were placed into a variety of different salt solutions a pH reduction was observed as the organisms grew. The growth rate of halophilic bacteria was examined at room conditions, 37°C and 41°C. Growth was very slow at low temperatures. Halotolerant bacteria and halophilic bacteria grew best at 37°C. The original hide samples used as the source of these halophilic bacteria had a fishy odor and a large area of reddish discoloration on the flesh side typical of "red heat".

Titre : Isolation and identification of bacteria adversely affecting hide and leather quality Type de document : texte imprimé Auteurs : Meral Birbir, Auteur ; A. Ilgaz, Auteur Année de publication : 1996 Article en page(s) : p. 147-153 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Two hundred and twenty five hide and chrome tanned leather samples were examined at different stages of processing to characterize the populations of organisms inhabiting them. Bacillus subtilis, bacillus cereus, bacillus pumilus, bacillus licheniformis, bacillus megaterium, bacillus sphaericus, micrococcus luteus, staphylococcus aureus, micrococcus rubens, kurthia variabilis, pseudomonas aeruginosa, staphylococcus epidermidis, bacillus brevis, micrococcus luteus, pseudomonas aeruginosa, staphilococcus aureus and staphylococcus epidermidis were positive for gelatin hydrolysis.
Fresh and salted hide samples were also evaluated chemically and histologically. Some of the salted hide samples showed histological changes resulting from poor curing techniques and high moisture content. It has been noted that generally bacillus species caused deterioration ofhides. It is concluded that the hide damage is caused by inadequate curing, bacterial action and autolysis.En ligne : https://drive.google.com/file/d/1wBdvyUn7rY8MUlQ9QsFKNBEyIBclyeL7/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8093
