Vim li cas PLA polylactic acid raug nqi?

Lub ntsiab yog vim li cas rau cov nqi ntau lawm ntawm PLA polylactic acid yog cov txheej txheem ntawm kev tsim cov lactic acid nrog siab kho qhov muag purity (98 ~ 99%), thiab tus yuam sij rau kev tswj cov qib siab ntawm fermentation efficiency nyob rau hauv cov tsoos lactic acid fermentation txheej txheem yog kev tswj cov concentration, kub, PH nqi, thiab lwm yam, nrog rau kev cog qoob loo ntawm cov kab mob fermentation heev. Txog rau qhov kawg no, txhawm rau txhawm rau txhim kho kev ua haujlwm ntawm fermentation, kev tshawb fawb tam sim no tab tom txhim kho cov enzymes thiab hom kab mob, suav nrog biotechnology xws li cov kab mob hloov pauv.
