結(jié)論

在本研究中，從被石油烴污染的海洋環(huán)境中獲得了 18 株耐寒且能夠產(chǎn)生生物 SAC 的分離株。 分離物是假單胞菌屬、假交替單胞菌屬、紅球菌屬、鏈球菌屬、Cobetia、Glaciecola、Marinomonas、Serratia 和 Psychromonas 的成員。 其中，紅球菌屬。 LF-13 和紅球菌屬。 在油性底物（如煤油、正十六烷或菜籽油）存在的情況下，LF-22 能夠顯著降低培養(yǎng)基的表面張力。 兩種菌株中的生物表面活性劑合成不一定與生長相關(guān)，這表明靜息細(xì)胞可用于從兩種紅球菌菌株中生產(chǎn)生物表面活性劑。 從紅球菌屬中提取的生物表面活性劑。 菌株 LF-22 能夠提高正十六烷在 13°C 的生物降解率。 應(yīng)純化這些分離物中的生物表面活性劑，以進(jìn)一步闡明其化學(xué)結(jié)構(gòu)和特性，并研究其在溢油生物修復(fù)和其他行業(yè)中的應(yīng)用。
