Chitosan and Other Polyamines: Antifungal Activity and Interaction with Biological Membranes
The antifungal effect of chitin has been demonstrated in field experiments. A marked reduction of root-rot in beans and of vascular wilt in radishes, both caused by Fusarium spp., were observed subsequent to addition of chitin to soil (1). Chitin amendment suppressed total fungal population and stimulated lytic and antibiotic-producing microorganisms such as actinomycetes (2–4). The antifungal effect of chitin thus was indirect, via antagonistic soil microorganisms.
