The fuel acclimation process offers flexibility in microbial fuel cell (MFC) power generation behavior. Different concentrations (50–200 mg/L) of phenol were used for adapting the activated sludge (AS), obtained from a local petroleum wastewater treatment plant and Ralstonia eutropha pure culture. Anodic biomass capable of oxidizing phenol substrate, using either AS inoculum microbial consortium or R. eutropha in the MFC system, has been a reflection of growth supportive functionality of phenol and 150 mg/L as initial concentration was used in the experiments. For both types of inocula. The results of phenol and COD removals obtained for closed system configuration were compared with those under open circuit condition. The current production by AS and R. eutropha was improved through phenol acclimation process. The highest power density (PD) using either AS or R. eutropha was 11 and 5.8 mW/m2, respectively. In terms of using olive oil mill wastewater as the anodic substrate, the behavior of phenol-acclimated R. eutropha was better than that of the synthetic type of wastewater, and the PD value was 7.8 mW/m2.

微生物燃料电池中的苯酚驯化活性污泥和真养产碱菌用于去​​除工厂废水中的橄榄油

燃料适应过程为微生物燃料电池 (MFC) 发电行为提供了灵活性。不同浓度（50-200 毫克/升）的苯酚用于适应从当地石油废水处理厂和真养产碱菌纯培养物获得的活性污泥（AS）。在 MFC 系统中使用 AS 接种微生物聚生体或 R. eutropha 能够氧化苯酚底物的阳极生物质反映了苯酚的生长支持功能，实验中使用的初始浓度为 150 mg/L。对于两种类型的接种物。将封闭系统配置获得的苯酚和 COD 去除结果与开路条件下的结果进行比较。目前AS和R. eutropha的产量通过苯酚驯化过程得到改善。使用 AS 或 R. eutropha 的最高功率密度 (PD) 分别为 11 和 5.8 mW/m2。在以橄榄油厂废水为阳极底物方面，苯酚驯化型富养R. eutropha 的行为优于合成型废水，PD 值为7.8 mW/m2。
