Abstract

Due to the low bioavailability and insolubility of high molecular weight polycyclic aromatic hydrocarbons (HMW-PAHs) in aqueous solutions, their degradation efficiency is significantly limited in wastewater treatment and environmental remediation. To address this challenge, we designed oil-in-water (O/W) macroemulsion (ME) bioreactors with mixed surfactants (Tween-80 and Triton X-100), n-butanol, corn oil, and Burkholderia vietnamiensis (BVs) to enhance the degradation efficiency of pyrene. Owing to the higher solubility of pyrene in MEs, it could be easily adsorbed onto hydrophobic groups on the cell surface. Furthermore, the fluorescence images showed that the BVs were adsorbed on the surface of the MEs, increasing the contact frequency and interactions between pyrene and BVs. Meanwhile, the degradation efficiency of the prepared ME bioreactor was improved by up to 198% compared to that of the conventional surfactant. Therefore, the constructed ME bioreactors can provide green guidance for HMW-PAH biodegradation in industrial wastewater and environmental remediation.

液-液界面大乳液（ME）生物反应器中不溶性高分子量多环芳烃的生物降解

由于高分子量多环芳烃（HMW-PAHs）在水溶液中的生物利用度低、不溶性好，严重限制了其在废水处理和环境修复中的降解效率。为了解决这一问题，我们设计了油包水（O/W）大乳状液（ME）生物反应器，混合表面活性剂（Tween-80和Triton X-100）、正丁醇、玉米油和越南伯克霍氏菌（BVs），以提高芘的降解效率。由于芘在MEs中的溶解度较高，它可以很容易地吸附在细胞表面的疏水性基团上。此外，荧光图像显示，BVs被吸附在MEs表面，增加了芘与BVs的接触频率和相互作用。与常规表面活性剂相比，制备的生物反应器的降解效率提高了198%。因此，所构建的ME生物反应器可为工业废水中高分子量多环芳烃的生物降解和环境修复提供绿色指导。
