The Synergistic antibacterial effects of Chitosan combined with rocephin against Escherichia coli

Zhihui Luo, Qingsheng Wu*, Meng Zhang

 

Abstract: In this study, the synergistic antibacterial efficiency of Chitosan and rocephin against Escherichia coli (E. coli) is investigated. Diameter of inhibition zone (DIZ) measurement show the antibiotic action of Chitosan-rocephin complex was better than the superposition of pure Chitosan and rocephin. The infrared ray (IR) spectrum and ultraviolet-visible (UV-vis) absorbance spectrum indicate that Chitosan is bond with rocephin and form a stable antibacterial group to restrain the growth of E. coli.
