ʻO ka pauka polylysine meaʻai ʻano meaʻai kūlohelohe
Hōʻike huahana
ʻO ka polylysine he polymer i haku ʻia me nā monomers lysine, ʻike pinepine ʻia ma nā ʻano kūlohelohe a i ʻole nā mea hana. Loaʻa iā ia nā ʻano hana like ʻole, me ka ʻoihana meaʻai, ka lāʻau lapaʻau a me ka biotechnology.
ʻO ka Polylysine (ε-poly-L-lysine, EPL) kahi homopolymer kūlohelohe liʻiliʻi o ka amino acid L-lysine pono i hana ʻia e
fermentation bacteria. Hoʻohana ʻia ka ε-Poly-L-lysine ma ke ʻano he mālama kūlohelohe i nā huahana meaʻai. ʻO ka ε-Polylysine no ka hui o nā polymers cationic. I loko o ka wai, loaʻa i ka ε-polysine kahi hui amino hydrophilic i hoʻopiʻi maikaʻi ʻia. Wahi a ka noiʻi, hoʻopili ʻia ka ε-polysine i ka electrostatically i ka ʻili o ka cell cell o ka bacteria, a ukali ʻia e ka wehe ʻana i ka membrane o waho.
ʻIke ʻia ʻo ε-Polylysine ma ke ʻano he mea palekana loa i ke kaiāulu ʻepekema. ʻIke ʻia ka ε-Polylysine ma ke ʻano he mālama mālama meaʻai i ʻOkakopa, 2003. Ua ʻae ʻia no ka hoʻohana ʻana ma ke ʻano he antimicrobial agent i ka laiki i kuke ʻia a i ʻole sushi raiki ma nā pae a hiki i 50 milligrams no ka kilo (mg/kg) o ka laiki. ʻO nā hopena o kahi noiʻi ʻawaʻawa nui a me nā hoʻāʻo bacterial no ka mutagenicity e hōʻike ana ʻaʻole ʻawaʻawa ʻo ε-Polylysine a ʻaʻohe mea hōʻike no ka hana mutagenic o ε-Polylysine. No laila palekana loa ʻo ε-Polylysine e hoʻohana ʻia ma ke ʻano he mālama meaʻai.

Hana
- Mea mālama meaʻai:Hoʻohana nui ʻia ʻo Polylysine ma ke ʻano he mea mālama meaʻai, hiki iā ia ke pale i ka ulu ʻana o ka bacteria, mold a me ka hū a hoʻonui i ke ola o ka meaʻai. Hiki iā ia ke pani i nā mea hoʻomalu kemika kuʻuna a ʻoi aku ka maikaʻi o ka palekana o ka meaʻai.
- Kahua lāʻau lapaʻau:Loaʻa i ka Polylysine nā mea antibacterial a me nā antiviral a no laila ua hoʻohana ʻia i ka lāʻau lapaʻau, e like me ka mea hoʻomalu a i ʻole antibacterial agent i loko o nā mea hana lāʻau. Eia kekahi, hoʻohana ʻia ia i nā ʻaʻahu lapaʻau a me nā ʻōnaehana hoʻokuʻu lāʻau.
- Biotechnology:Ma ke kahua o ka biotechnology, hoʻohana ʻia ka polylysine i mea hoʻohui i ka media moʻomeheu cell e kōkua i ka ulu ʻana a me ka hoʻonui. Hiki ke hoʻohana ʻia e ʻōwili a pale i nā molekala nucleic acid e like me DNA a me RNA no ka hoʻololi ʻana o ka gene a me nā hoʻokolohua hoʻololi.
ʻO ka holoʻokoʻa, ʻo ka polylysine he hui multifunctional me kahi ākea o nā noi, me ka mālama ʻana i ka meaʻai, antibacterial a me nā hopena antiviral i ka lāʻau lapaʻau, a me ka moʻomeheu cell a me ka pale nucleic acid i ke kahua biotechnology.
