Studies of application possibilities of the products of microcrystalline chitosan

biodegradation (in English)
Polimery 2007, No 3, 217


Summary

Some of the chitosan properties depend largely upon its molecular structure and in several applications of this polymer its lowered molecular weight is an asset. By degrading of microcrystalline chitosan in the presence of cellulolytic enzymes, the products having a reduced molecular weight were prepared, together with awater soluble blend of oligomers. The outcome of an initial assessment, made to evaluate the chance of a practical use of the obtained products of chitosan degradation, indicates that oligomers and partly degraded microcrystalline chitosan accelerate the germination of seeds, inhibit the growth of plant viruses, bacteria and milder.


Key words: chitosan, enzymatic degradation, oligomers, plant pathogens
