Chitosan Oligosaccharide
Aha sayensị nke chitosan oligosaccharides bụ B-1,4-oligosaccharide glucosamine, Ọ bụ ngwaahịa oligosaccharide nwetara site na chitosan na-emebi emebi, site na teknụzụ teknụzụ pụrụ iche. molecular arọ s3000Da, ezigbo mmiri solubility, nnukwu ọrụ na obere molekụla arọ ngwaahịa nwere nnukwu ọrụ ndu.
Ọ nwere solubility dị elu nke chitosan enweghị, yana soluble kpamkpam na mmiri. O nwere ọtụtụ ọrụ pụrụ iche dị ka ihe dị ndụ na-etinye ya ngwa ngwa ma jiri ya mee ihe, mmetụta ya bụ ugboro 14 karịa nke chitosan. cationic isi amino oligosaccharides na ọdịdị na bụ anụmanụ cellulose.
1.lprove ala gburugburu
Enwere ike iji Chitosan oligosaccharides mee ihe dị ka ihe na-akpali akpali iji gbanwee ahịhịa ala ma kwalite uto nke microorganisms bara uru. Chitosan oligosaccharides nwekwara ike ịkpata nguzogide ọrịa osisi, ma nwee mmetụta mgbochi na igbu egbu n'ụdị fungi, badteria na nje. The uka mmeputakwa nke microorganisms nwere ike ịkwalite fomation nke ala mkpokọta Ọdịdị, melite anụ ahụ na chemical Njirimara nke ala, enhanoe na pemeability na ike idowe mmiri na fatịlaịza; si otú a na-enye ezigbo ala micro-ecological gburugburu ebe obibi maka mgbọrọgwụ usoro, nke mere na dị iche iche nri na ala na-arụ ọrụ nke ọma-ise ise.
2.Induce osisi na-eguzogide ọrịa na nrụgide nrụgide
Chitosan oligosaccharides, dị ka onye na-eguzogide ihe ọkụkụ, nwere ike ịkpata nguzogide ọrịa nke osisi, mee ka ihe nchebe nke osisi ghara ịlụso ọrịa ọgụ, na-eguzogide oyi, oke okpomọkụ, ụkọ mmiri ozuzo na mmiri mmiri, salinity, mmebi fatịlaịza, mmebi ikuku, iguzogide nguzozi nri. Nhazi lignin kpatara Lignin bụ isi ihe dị na mgbidi cell nke abụọ nke anụ ahụ vaskụla osisi, nke n'onwe ya na-eguzogide mmebi microbial. Chitosan oligosaccharides nwere ike ịkpalite lignification gburugburu ebe nje butere osisi, na-akpụ ihe mgbochi anụ ahụ, si otú a na-egbochi ma ọ bụ na-egbu oge uto na difusion nke pathogens na gburugburu nomal anụ ahụ, na ịkwalite ọrịa resistanoe nke osisi.
3. Enwere ike iji ya mee ihe dị ka onye na-ekpuchi mkpụrụ osisi, ihe na-edozi mkpụrụ
Ndị na-ahụ maka uto osisi na ndị na-ahụ maka nje bacteria nwere ike ime ka osisi na-emepụta protein PR (ụdị protein nke osisi na-emepụta ma na-emesi ike site na pathogens ma ọ bụ ihe ndị ọzọ) na phytochemicals, na-eji amino oligosaccharides dị ka ihe ndị bụ isi iji kesaa fatịlaịza kemịkalụ, Mmepe nke mkpuchi mkpụrụ ọhụrụ. ndị ọrụ nwere ihe ndị na-achọpụta ihe.
4.Plant ọtọ fatịlaịza
Chitosan oligosaccharides na-ejikọta ya na ndị na-anabata akpụkpọ ahụ cell, na-ebufe akara eletrik, na-eme ka ụzọ dị iche iche na-alụso ọrịa ọgụ ọgụ, na-eme ka mgbidi cell dịkwuo elu, na-abawanye substano dị iche iche na-eguzogide ọgwụ na ihe ndị na-arụ ọrụ n'ime sel, na-akpali ihe ọkụkụ iji meziwanye nguzogide na ịkwalite uto. mmetụta Chitosan oligo-saccharides na-ejikọta ya na nri enwetara iji nweta nsonaazụ kacha mma.
