生物表面活性剂是分子结构中既有亲水基、又有憎水基的两性分子物质。它们可生物降解,对环境友好,并具有润湿、分散、乳化、增溶、起泡、保湿、润滑、洗涤、渗透等性能,因而能够应用于生产、生活的多个领域,尤其在食品、化妆品行业、医药行业和微生物采油(MEOR)方面生物表面活性剂具有合成表面活性剂不可比拟的优点。 本文选取一株柴油食烷菌AlcanivoraxdieseloleiT6-6为研究对象,它是一株分离自西南印度洋深海沉积物的海洋细菌,该菌株不仅具有优良的烃降解能力而且在以正十六烷为唯一碳源的液体培养基中可以将发酵液的表面张力降至27mNm-1左右。 将菌体发酵液冷冻离心后发现表面活性物质主要存...Biosurfactant is one kind of amphipathic molecule that not only has the hydrophilic groups but also has the hydrophobic ones. It is noticed in many fundamental and applied research fields because of its numerous merits, such as excellent emulsification, aidant dissolvability, degradable, nontoxic. In this thesis, one strain which identified as Alcanivorax dieselolei T6-6 that could not only degrad...学位:理学硕士院系专业:生命科学学院_细胞生物学专业学号:2172009115217
