Petroleum wastewater samples from oil refinery and oil exploration site were treated by hyper phenol-tolerant Bacillus cereus (AKG1 and AKG2) in laboratory-scale batch process to assess their bioremediation efficacy. Quality of the treated wastewater samples were analyzed in terms of removal of chemical oxygen demand (COD), total organic carbon (TOC) and ammonium nitrogen content, and improvement of biological oxygen demand (BOD). Adaptation of these bacteria to the toxic environment through structural changes in their cell membranes was also highlighted. Among different combinations, the co-culture of AKG1 and AKG2 showed the best performance in degrading the wastewater samples.
在实验室规模的间歇过程中,采用超耐苯酚蜡样芽孢杆菌(AKG1和AKG2)处理来自炼油厂和石油勘探场地的石油废水样本,以评估其生物修复效果。从化学需氧量(COD)、总有机碳(TOC)和铵氮含量的去除以及生物需氧量(BOD)的改善方面,对处理后的废水样本质量进行了分析。还强调了这些细菌通过细胞膜结构变化对有毒环境的适应性。在不同组合中,AKG1和AKG2的共培养在降解废水样本方面表现最佳。
