The in vitro antibacterial activity and mechanism of action of two kinds of acid-soluble
chitosan and one water-soluble chitosan against apricot fruit rot pathogen Burkholderia
seminalis was examined in this study. Results showed that water-soluble chitosan displayed
limited antibacterial activity at four tested concentrations. However, two kinds of acid-soluble
chitosan solution at 2.0 mg/mL had strong antibacterial activity against B. seminalis although
weak antibacterial activity was observed at a concentration lower than 1 mg/mL. The …
