Immobilization of Lysozyme on Food Contact Polymers as Potential Antimicrobial Films

Effective Pretreatment Routes of Polyethylene Terephthalate Fabric for Digital Inkjet Printing of Enzyme

“…Even after five print‐passes fabrics were not saturated by enzymes as activity plateau was not reached, though printed ink started to flow through the back side of fabrics. Therefore, highest possible protein concentration compatible with ink formulations could be used, [ 28 ] even after linear range, to achieve higher activity from inkjet printed fabrics, instead of printing for several passes.…”

Evaluation of the Antimicrobial Potential of Alginate and Alginate/Chitosan Films Containing Potassium Sorbate and Natamycin

“…The pH of the film forming solution of pure AF was close to 7, whereas the pH for composite films was approximately 5.5, which could suggest that the lower inhibition effect is due to NA chemical degradation. Several studies in the literature point out that the antimicrobial effect of active films and coatings is related to antimicrobial substance action mode and spectra but also to the interaction between the film matrix and the active substance . Chen et al ., investigated the effect of adding 2% KS and sodium benzoate to methyl cellulose and to chitosan films against Rhodotorula rubra and Penicillium notatum .…”

Immobilization of Bacillus licheniformis α-amylase onto reactive polymer films

“…Enzyme immobilization has the additional advantage of minimizing health concerns, as for example when used in food packaging applications (Appendini and Hotchkiss, 1997), and of improved efficacy, as for example by locating the enzyme at the surface-fouler interface in antifouling technology (Hangler et al, 2009;Tasso et al, 2009b). Immobilization usually leads to an increase of enzyme activity, selectivity, and stability (Cao, 2006;Mateo et al, 2007;Sheldon, 2007).…”
