Production of metal-containing protein fibers and their antimicrobial activities

摘要：

　　Protein fibers made of Bombyx mori, Antheraea pernyi, and wool yarn were treated with tannic acid (TA) or chemically acylated with ethylenediaminetetraacetic (EDTA)-dianhydride.The uptake of different metal ions (Ag+, Cu2+, Co2+) by protein fibers, chemically modified, was studied as a function of weight gain and pH of the aqueous metal solution.Below pH 7, absorption of metal ions by untreated and TA-treated fibers was negligible.Acylation with EDTA-dianhydride to fibers enabled protein fibers to absorb and bind significant amounts of metal ions in the acidic as well as in neutral pH range.Untreated protein fibers usually displayed the lowest stability of the metal complex.Metal complexes with protein fibers exhibited prominent antimicrobial activity against the plant pathogen Cornebacterium.
