Salicyloyl Chitosan/Starch blend (SCSB) was prepared in two steps. In the first step, chitosan was modified as Salicyloyl chitosan (SCS) by treating with Salicyloylic acid and in the next step the prepared Salicyloyl chitosan (SCS) was blended with starch. Thus, synthesised blend was characterized by FTIR, XRD and TGA. The antibacterial activities were assessed against Escherichia coli (E.coli), Staphylococcus aureus (S.aureus) and Proteus Mirablis by Inhibition Zone method. The antifungal activities against Candida albicans, Aspergillus niger and Aspergillus flaus were also assessed by the same method. The structure activity relationship of SCS and SCSB for the anti-microbial activities was also discussed.
