Figure 1. Response surface 3D-plot of optimization of degree of
deacetylation (% DD) of chitosan extraction.
Figure 2. Desirability ramp for optimization of (% DD) of chitosan
extraction.
Figure 3. Fourier Transform Infrared Spectroscopy (FTIR) of extracted
Chitosan from shrimp.
Figure 4. The impact of sub-Minimum inhibitory concentration (MIC)
concentrations of shrimp-derived chitosan (CS) on the factors involved
in quorum sensing of Pseudomonas aeruginosa. (a): pyocyanin production,
(b): rhamnolipid production, (c): swimming motility, (d): protease
activity, (e and f): expression of rthIR and lasR genes. Significant
differences among the groups are denoted by distinct letters
(P<0.05) (n=6).
Figure 5. The impact of sub-MIC concentrations of CS on biofilm
formation of Pseudomonas aeruginosa.
