초록

There are several factors in the degradation of textiles. The crucial factors in textile weakening are humidity, dust, smoke, sunlight, microorganisms and so on. Especially silk fabrics are more susceptible to microorganisms than other fabrics, because they are mainly consisted of proteins. In this study, we investigated the activities for degrading casein and silk fibers with 2 strains, Bacillus cereus TX1 and Pseudomonas fluorescens TX 2, isolated from domestic museums. They were compared to those of standard control strains, Klebsiella pneumoniae and Staphylococcus aureus, usually used for the antibiotic test of fabrics. The caseinolytic activities of K. pneumoniae and S. aureus were higher than those of isolated strains. But in the cases of silk fiber degrading, B. cereus TX 1 showed the highest activity on both silk 1 and silk 2. Therefore, caseinolytic activities were not coincident with the activity to degrade silk fibers. All strains degraded silk 1(strength retention 100%) better than silk 2(strength retention 50%). It means that bacteria mainly participate in the early stage of degrading silk fabrics, but as time goes by, the importance of bacteria for degrading silk fabrics would decreased. Even though the importance of bacteria may decrease, controlling bacterial activity is necessary to preserve historic silk fabrics.
