Synthesized OH-radical rich bacteria cellulosic pockets with photodynamic bacteria inactivation properties against S. ureus and E. coli.

Inulin as an external carbon source was used as the fructose substitute to Gluconacetobacter xylinus (ATCC 10245) bacterial strain in a successful synthesis of cellulosic pockets to be used in drug delivery and storage. It was observed that inulobiose trans conformation was in agreement with ϕ = Ψ = ω = 180° and angular rotation of ϴ (C1-C2-0-CI''), ϴ (C2-0-C 1'-C2') and ϴ (0-C1'-C2'-0') respectively. A bacterial susceptibility test revealed a successful inactivation of Staphylococcus aureus and Escherichia coli in the presence of photons. Fourier Transform Infrared Spectroscopy analysis confirmed an OH absorption was verified at 3423 cm. Pocket drug uptake test revealed a highly absorbent structure with the thermal stability directly proportional to the increase in drug uptake, while the increase in the degree of polymerization resulted in the increase in antioxidant activity and rate of bacterial inactivation. HYPOTHESIS: Inulin as an inert polysaccharide is neutral to cellular activity, therefore, could not be an agent for bacteria inactivation.
