Is al biodegradable?
•Polylactic acid, anozivikanwawo sePla, anga ave nemakore mazhinji. Nekudaro, vagadziri vepla vakangopinda nguva pfupi yapfuura vakapinda mumusika mushure mekuchengetedza mari kubva kumakambani makuru anochiva mapuranga echiSynthetic. Saka, isa biodegradable?
•Ipo mhinduro isiri nyore, takasarudza kupa tsananguro uye kurudzira kumwe kuverenga kune avo vanofarira. Plah haisiri biozozandable, asi zvinosvibisa. Enzymes iyo inogona kuputsa isina kumbowanzoshandiswa mune zvakatipoteredza. Proteinase k is enzyme iyo inodzidzisa kusvibiswa kwePla kuburikidza hydrolysis. Vanotsvagurudza vakadai saWilliams muna 1981 uye Tsuji naMiyauchi muna 2001 vakaongorora nyaya yekuti Play iri bioDogradable. Mhedzisiro yavo inokurukurwa mubhuku Biomatsials Sayenzi: Nhanganyaya yezvokukurapa uye inoburitswa pamusangano weEuropean Biomaterials Sangano. Zvinoenderana nezvinhu izvi, pla inodzorwa zvakanyanya ne hydrolysis, yakazvimiririra chero chero vamiriri vebiologic. Nepo vanhu vazhinji vanogona kufunga kuti Pla iri bioDogradable, zvakakosha kuti uzive izvi.
•Muchokwadi, hydrolysis ye plpredinase k inoshamisa kuti haina kukosha zvakakwana kuti ienderane nekuenderera mberi muBiomeraal sainzi. Isu tinovimba izvi zvinojekesa nyaya dzakapoteredzwa pachena
In mhedziso:
Pla ndeye biocalable epurasitiki zvakanyanya anoshandiswa mune zvezuva nezuva zvinhu zvakaita sehombodo dzekurasa uye makapu. Nekudaro, inogona kungosvibisa muindasitiri kuumbwa kana anaerobic yekugayera nzvimbo, kuita kusvibiswa mumamiriro ezvinhu epanyama anonetsa. Zvidzidzo zvakasimbisa iyo pla degrades zvishoma munzvimbo yemarine.
