“…When the fengycin concentration in the two lipopeptide preparations with and without commercial surfactin added was set at 600 g/ml, the inhibition of hypha growth was found to be 75.6% and 86.4%, respectively. According to previous reports, when the chitosan concentration was set at 3.0 mg/ml, the inhibition of hypha growth in R. stolonifer was about 70% (Guerra-Sánchez et al, 2008). It is noteworthy that fengycin used in this study has significantly greater antifungal activities against R. stolonifer relative to other compounds.…”

The antifungal activity and mechanism of fengycin in the presence and absence of commercial surfactin against Rhizopus stolonifer were investigated. The MIC (minimal inhibitory concentration) of fengycin without commercial surfactin added was 0.4 mg/ml while the MIC of fengycin with commercial surfactin added was 2.0 mg/ml. Fengycin acted on cell membrane and cellular organs and inhibited DNA synthesis. The antifungal effect of fengycin was reduced after commercial surfactin was added. All these results suggest that the fungal cell membrane may be the primary target of fengycin action and commercial surfactin may reduce the antifungal activity of fengycin.

“…Spore germination and germ-tube elongation of A. kikuchiana and P. piricola were significantly inhibited by chitosan and oligochitosan, although when compared to chitosan, oligochitosan was more effective for the inhibition of spore germination (Meng et al, 2010a). However, other investigations have shown fungal growth inhibition by chitosan, regardless of the type of chitosan (Chien and Chou, 2006), without any fungicidal or fungistatic patterns among low, medium, and high molecular weight chitosans tested with different isolates of C. gloeosporioides (Bautista-Baños et al, 2005) and R. stolonifer (Guerra-Sánchez et al, 2009). …”

Among alternatives that are currently under investigation to replace the use of synthetic fungicides to control postharvest diseases in fresh produce and to extend their shelf life, chitosan application has shown promising disease control, at both preharvest and postharvest stages. Chitosan shows a dual mode of action, on the pathogen and on the plant, as it reduces the growth of decay-causing fungi and foodborne pathogens and induces resistance responses in the host tissues. Chitosan coating forms a semipermeable film on the surface of fruit and vegetables, thereby delaying the rate of respiration, decreasing weight loss, maintaining the overall quality, and prolonging the shelf life. Moreover, the coating can provide a substrate for incorporation of other functional food additives, such as minerals, vitamins, or other drugs or nutraceutical compounds that can be used to enhance the beneficial properties of fresh commodities, or in some cases the antimicrobial activity of chitosan. Chitosan coating has been approved as GRAS substance by USFDA, and its application is safe for the consumer and the environment. This review summarizes the most relevant and recent knowledge in the application of chitosan in postharvest disease control and maintenance of overall fruit and vegetable quality during postharvest storage.

“…Chitosan C1 and C2 exhibited 100 % reduction in colony size against P. decumbens CBS 121928 at the concentrations of 0.5-0.125 %w/v while chitosan C3 showed 100 % inhibition at 0.5 %w/v. Inhibition of fungal growth with increasing chitosan concentrations in agar plates has been reported in several studies (Guerra-Sánchez et al 2009;Li et al 2009;AlHetar et al 2011;Cota-Arriola et al 2011;Rahman et al 2014). Although increasing the concentrations of chitosan may increase the antimicrobial efficacy of chitosan on many fungi and bacteria, this trend depends on several factors such as Mw, F A , targeted pathogen and pH (Younes et al 2014).…”

Resistance of rubberwood (Hevea brasiliensis) treated with chitosan or silane against surface molds

et al. 2016

The aim of this study was to determine the efficacy of chitosan and methoxysilane in the prevention of surface mold growth on rubberwood. Three different chitosan samples were tested; C1 (Mw 37 kDa), C2 (Mw 5.4 kDa) and C3 (Mw 3.5 kDa). Radial growth inhibition assay of the chitosan samples was investigated at concentrations ranging from 0.063 to 0.5 %w/v against Aspergillus niger BAM 4 and Penicillium decumbens CBS 121928. Chitosan samples C1 and C3 exhibited strong antifungal activity against both molds. Rubberwood samples were either vacuum or dip treated with varying concentrations of chitosan or silane solution. The content of chitosan in wood showed that after the leaching test, chitosan was well retained in both vacuum and dip treated wood. The concentration of silicon in wood showed similar results. The vacuum treated wood samples with chitosan C1 and C3 at 1 %w/v concentration had strong resistance against A. niger BAM 4. However, dip treated rubberwood samples with 2 %w/v chitosan solutions showed lower resistance against A. niger BAM 4. On the other hand, both vacuum and dip treated rubberwood samples with chitosan had no resistance against P. decumbens CBS 121928. The silane treated wood samples showed no resistance to fungal growth.
