This shows the antibacterial activity of chitin and chitosan. This was consistent with the previous study by
Gerasimenko, Avdienko, Bannikova, Zueva, and Varlamov (2004) who reported the antimicrobial activity of chitosan on S. aureus. They further reported that chitosan with Mv of 12 kDa was more effective in inhibiting cell growth than the chitosan with Mv of 27 kDa.
