    Application of &#945;-Amylase in Combination with Ultrasound to Remove Starch Based Adhesives from Paper

  • Original language description

    &amp;#945;-Amylases are enzymes employed in paper conservation to remove starch-based adhesives. However, the success of their application can be limited by the transport rate of the enzyme molecules through the paper pores to the substrate. This investigation was focused to monitoring the penetration rate of the enzyme into paper and various means of accelerating it. Special attention was paid to using power ultrasound of 20 kHz and a 3 mm diameter sonotrode. The measurement was performed using a vertical static diffusion cell. It was found that the process can be accelerated up to thirty times by using ultrasound. The portability of the results to practical applications was verified on model samples of pasted joints. The work also included testing the effect of ultrasound on the catalytic activity of the enzyme and on selected properties of the paper. No negative effect was observed under the given experimental conditions.
