Iyini i-Polyhydroxybutyrate PHB ene-CAS 26744-04-7?

I-PHB ikhiqizwa ama-microorganisms, ngokusobala ekuphenduleni izimo zokucindezeleka ngokomzimba. Ikakhulukazi isimo somsoco olinganiselwe. I-polymer ngokuyinhloko iwumkhiqizo we-carbon assimilation (kusuka ku-glucose noma isitashi) futhi isetshenziswa ama-microorganisms njengendlela yokugcina amandla e-molecule ye-metabolism lapho eminye imithombo yamandla evamile ingekho.

Isicelo

I-PHB inamathemba abanzi okusetshenziswa kwezinto zokwelapha, amapulasitiki awonakaliswayo, izinto zetafula ezilahlwayo, amafreyimu embukiso, ukupakishwa, ukulahlwa kwendle, amathoyizi neminye imikhakha.
Ezolimo: umthwali we-biodegradable wamafilimu ezolimo, izibulala-zinambuzane ezisebenza isikhathi eside nomanyolo
Umuthi: Izindwangu zokuhlinza, izinzipho zendololwane, ukubuyisela amathambo, ukushintshwa kwemithambo yegazi Imboni: izinto zokupakisha, imikhiqizo yenhlanzeko, amanabukeni, izinto ezisebenzayo ezibonakalayo
Emkhakheni wezinto zokwelapha, i-polyhydroxybutyrate ingasetshenziswa ukulungisa izinto ezithwala izidakamizwa ezikhishwa njalo, izinto zokwakha ubunjiniyela bezicubu, njll. Emkhakheni wokupakisha, imikhiqizo yokuwohloka kwe-polyhydroxybutyrate ikakhulukazi i-carbon dioxide namanzi, okuhambisana nokuhlaza kwamanje. kanye nomqondo wokuthuthukiswa kokuvikelwa kwemvelo.
