摘要:
Thin layers of silver particles (10-100 angstrom) were deposited by plasma technology on textiles mainly composed with cotton or polyester in order to obtain antimicrobial properties. The antimicrobial activity against a Listeria innocua strain (LRGIA 01) of these textiles was assessed following a protocol based on the ISO 20743-2005 standard. The number of cultivable bacteria on textiles was then monitored for 24 h. The microbial population after 24 h at 30 degrees C attained 10(7) CFU g(-1) on control textiles while it did not exceed 10(3) CFU g(-1) on plasma-treated textile. All plasma-treated with silver textiles were anti-Listeria (up to 7 log CFU g(-1) decimal reductions of L. innocua populations) and this observation was confirmed by scanning electron microscopy. These textiles could thus have potential applications in food-processing industry to control cross-contaminations by L. monocytogenes. (C) 2009 Elsevier Ltd. All rights reserved.
