Polyhydroxyalkanoates los yog PHAs yog polyesters tsim los ntawm ntau yam kab mob, suav nrog los ntawm cov kab mob fermentation ntawm suab thaj lossis lipid. Thaum tsim los ntawm cov kab mob lawv ua haujlwm ua ob qho tib si lub zog thiab ua cov khw muag khoom carbon.

Tom qab ntawd, ib tus tseem tuaj yeem nug, PHA tsim tawm li cas?

PHA ntau lawm tshwm sim nyob rau hauv cov kab mob intracellular thaum cov cell tau ntsib nrog cov kev txwv tsis pub muaj txiaj ntsig zoo (piv txwv li nitrogen lossis phosphorous) thaum muaj cov pa roj carbon ntau dhau. Lawv lub luag haujlwm ntawm lub cev rau cov cell yog lub zog thiab cov khoom khaws cia carbon.

Ib qho ntxiv, puas yog PHA biodegradable? PHAs yog biodegradable , nkag yooj yim dua thermoplastics, ua los ntawm microbial fermentation ntawm carbon-based feedstocks. Cov khoom ntawm PHA polymers tuaj yeem hloov kho rau daim ntawv thov, nyob ntawm qhov tshwj xeeb ua ke ntawm cov sib txawv monomers suav nrog hauv cov saw polymer.

Hauv qhov no, PHA siv rau dab tsi?

PHA yog dav siv rau ntau yam kev siv tshuaj kho mob, suav nrog kev xa tshuaj thiab cov ntaub so ntswg engineering scaffolds, vim tias lawv zoo heev biocompatibility thiab biodegradability. Thawj thiab tshaj plaws PHA yog poly (β-hydroxybutyrate) (PHB).

PHA yuav siv sij hawm ntev npaum li cas kom decompose?

Biodegradable PHA fwj tawg hauv av tsis pub dhau 2 lub hlis (tab sis tseem nyob zoo li ntev raws li lawv tsis tau muab pov tseg).
