Muaj nuj nqi:
6-APA (6-Aminopenicillanic acid) yog lub hauv paus ntawm penicillins. Nws yog tau los ntawm fermentation brew ntawm Penicillium pwm thiab siv los ua lub ntsiab pib thaiv rau kev npaj ntawm ntau semisynthetic penicillins.
Ntim:
25kg / nruas los yog raws li koj xav tau.
Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias thiab airiness, tsis txhob muaj kev cuam tshuam thiab noo noo, kom nws deb ntawm oxides.
