Evaluating the antimicrobial efficacy of spun lace viscose fabric treated with chitosan extracted from metapenaeus dobsoni

The shells of metapenaeus dobsoni accumulated as waste were deproteinized and demineralized to obtain chitin. Chitin was deacetylated to chitosan, and its viscosity and degree of deacetylation were analyzed as per AOAC methods. Spun-lace viscose fabric was treated with 2 % chitosan and evaluated for antimicrobial property in dry and damp conditions. The zone of inhibition against S. aureus, E. coli, A. niger and C. albicans were (0,1), (0, 1), (3,3) and (3,3) mm respectively for dry and damp samples. The efficiency of the chitosan treated spun lace viscose fabric to inhibit the tested bacterial strains were more effective in damp condition than in dry condition.
