abstract = {The prevention of bacteria colonization by immobilizing
proteins with antimicrobial activity onto cotton fabrics was
investigated. Such coatings have potential applications in
medical dressing materials used in wound care and healing.
Two antimicrobial proteins lysozyme and hydramacin-1 (HM-1)
were surface immobilized through two linkers (3-aminopropyl)
triethoxysilane (APTES) and citric acid in the presence of
the water soluble carbodiimide coupling reagent
1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide
metho-p-toluenesulfonate. Surface composition analysis by
attenuated total reflection-Fourier transform infrared and
X-ray photoelectron spectroscopies confirmed formation of
the protein-cellulose conjugates. Antimicrobial activities
of the different functionalized surfaces were found to vary
between APTES and citric acid directed coatings. Citric acid
immobilized lysozyme treated samples demonstrated superior
activity against Gram-positive Bacillus subtilis, whereas
APTES immobilized HM-1 treated samples demonstrated an
advantage in inhibiting the growth of Gram-negative
Escherichia coli. The antibacterial activity and stability
of citric acid immobilized protein fabrics following
sonication, boiling and chemical treatment were noticeably
higher than that of the corresponding APTES immobilized
protein fabrics. The dual coating of fibers with both
antimicrobial proteins afforded efficient antimicrobial
activities against both bacterial species. The results
suggest that coating cotton fibers with antimicrobial
proteins and peptides represents a feasible approach for
developing active surfaces that prohibit growth and
colonization of bacterial strains and can be potentially
used in medical cotton-based fabrics.},
