Polypropylene glycol (PPG)-assimilating Sphingobium sp. strain PW-1 was grown on 0.5% PPG 700. PPG and its metabolites were analyzed by MALDI-TOF mass spectrometry. An oxidized form of a terminal alcohol group appeared with each molecular species as a metabolite. Cell-free extract showed PPG dehydrogenase activity. In this way, the oxidative metabolic pathway for PPG was confirmed.
能够同化聚丙二醇（PPG）的鞘氨醇单胞菌属（Sphingobium sp.）菌株PW-1在0.5%的PPG 700上生长。通过基质辅助激光解吸电离飞行时间质谱（MALDI-TOF质谱）对PPG及其代谢产物进行了分析。每种分子种类的代谢产物中都出现了末端醇基的氧化形式。无细胞提取物显示出PPG脱氢酶活性。通过这种方式，证实了PPG的氧化代谢途径。
