| Abstract | ||
| Spots and dirt are considered one of the most important destructive factors for antique textiles, and the process of searching for new techniques for treatment and maintenance is also a necessity to get rid of such stains and dirt. The study used one of the oxidation enzymes "Laccase enzyme isolated from the genus Alternaria tenuissima KM651985 in cleaning fungal stains on archaeological linen textiles, as well as using basal protease enzymes isolated from bacterial strains Bacillus lichiniformis P12 and Bacillus pumilus p19 in cleaning protein stains "blood stains". On the surfaces of linen textiles, the study relied, in the process of evaluating the effectiveness of the cleaning process with enzymes, on measuring the chromatic change values of the samples ΔE before and after the treatment process, as well as measuring the optical density of the washing solutions resulting from the treatment process using a spectro photometer. Fungal stains as well as enzyme efficiency The study concluded that the efficiency of the protease enzyme isolated from the genus Bacillus lichiniformis P12 was higher than the efficiency of the protease enzyme isolated from the genus Bacillus pumilus p19 in removing protein stains from the surfaces of linen textiles | ||
