Abstract:
In this work, the composite film based on Carboxy methyl cellulose (CMC) and
Gum Arabic (GA) were prepared by solution casting method. Calcium chloride was
used as a crosslinking agent with different ratios. The physical properties of the
composite film were investigated in terms of swelling percent (%) and the structure
of the composite film was characterized by Fourier transform infrared spectroscopy.
Antimicrobial activity in leaf extract of neem (Azadirachtolides) against human
pathogenic bacteria. E. coli, extract showed a broad spectrum of very significant
antibacterial activity by producing a clear zone of inhibition against, E. coli.
