Polysaccharide-Based Film of Cassia fistula and it's Antibacterial Activity

Abstract:

The film-forming potential of isolate of seed polysaccharide from Cassia fistula was investigated. Increasing the glycerol concentration in the film increased elongation at break, film solubility and water vapor permeability but decreased tensile strength (TS). The film impregnated with the acetone extract of Atractylodes lancea was assessed for inhibition of Escherichia coli and Staphylococcus aureus. The obtained results showed that the films exhibited antibacterial activity against both bacterial strains. Disc-diffusion assay revealed that the film resulted in a larger inhibition zone around the film on Staphylococcus aureus than it did on Escherichia coli at the same extract concentrations (0.1 to 0.9 wt %). It can be seen that the film has satisfactory physical and antibacterial properties.
