| Résumé : |
The quality of leather manufactured from brine-cured cattle hides is known to deteriorate on prolonged storage of the untanned hides, particularly at elevated temperatures.This deteriotation is probably due to the presence of proteolytic enzymes produced by microorganisms growing on the hide.Extensive research has been done on the identification of halophilic organisms in hides cured with solid salt, but much less information is available on the extremely halophilic organisms found on commercially brine-cured hides.
Brine-cured cattle hide samples were obtained from several commercial brine-curing operations over a period of one year.One hundred and thirty one samples were analyzed for halotorant,slightly, moderately, and extremely halophilic organisms.Halophilic organisms of all three types as well as halotolerant organisms were found on almost every brine-cured cattle hide sample tested.More than half of the 332 extremely halophilic isolates tested positive for proteolytic activity based on a gelatin plate assay.The majority of the proteolytic positive isolates appeared to be archaeobacteria, based on antibiotic sensitivity and lipid analysis.Measurement of the growth of four randomly selected isolates over a wide range of temperatures indicates that these organisms grow rapidly at elevated temperatures(35-42°C) and warrants further investigation to assess these organisms as a source of hide damage. |
