Evaluation of fungal chitosan as a biocontrol and antibacterial agent using fluorescence-labeling

Electron micrographs of treated E. coli with fungal chitosan revealed that chitosan principally interact with bacterial cell wall, causing cell wall lyses with exposure time prolongation. Fungal chitosan could be proposed for bacterial growth control as a powerful, natural and safe alternative to synthetic and chemical bactericides. Fluorescence labeling proved to be an efficient tool for determining the antimicrobial activity of chitosan.
