Egg albumin PVA hybrid membranes for antibacterial application

Antibacterial membranes of crosslinked PVA embedded Azadirachta indica and Curcuma longa were fabricated with egg albumin as crosslinking agent. The antibacterial property of the developed membrane was evaluated using agar plate method against Gram-positive and Gram-negative bacteria. A. indica-PVA membrane yielded 3-4 cm zone of inhibition against both the bacteria. A clear parametric dependence of the large zone of inhibition in membrane on uniform distribution of the additives was observed. This cost effective method eliminates the use of elaborated and sophisticated equipment′s used to fabricate membranes for biomedical application like wound healing, antibacterial, anti-fungal etc. © 2013 Elsevier B.V.
