The inhibitory effect of newly synthesized guar, chitosan and cellulose resins on the growth of pathogenic bacteria

Abstract

Guar, Chitosan and Cellulose based new chelating ionexchange
resins were synthesized. The inhibitory activity of Chitosan triazine phenyl alanine hydroxamate [CT-PAH],
Guar-triazine phenyl alanine hydroxamate [GT-PAH], Cellulose
epoxy leucine hydroxamate [CE-LH] and Cellulose epoxy histidine hydroxamate [CE-HH], against growth of
Escherichia coli, Staphylococcus aureus, Klebsiella pnemoniae
and Pseudomonas aeruginosa was evaluated.
These newly synthesized resins were characterized by
FT-IR, elemental analysis, NMR and Mass-spectra. Other
resin characteristics like bulk density, moisture content,
ion-exchange capacity, bulk volume and pH titrations were
also studied. The antibacterial activity was carried out using
agar disk diffusion method in which CT-PAH and CELH
showed bigger zones of inhibition than GT-PAH and
CE-HH. The results revealed that newly synthesized CTPAH
and CE-LH can be used as anti-microbial agents for
preservation and safety of edibles or eatables.
