Phenol and its derivatives are one of the major pollutants present in industrial effluents. In this work, Pseudomonas aeruginosa (ATCC 9027) has been effectively used to carry out biodegradation of phenol, 3-aminophenol, and catechol. In order to develop an industrially viable technology, P. aeruginosa has been immobilized on granular activated carbon (GAC). The biofilm thickness was found in the range 14 to 34 μm. The adsorbed P. aeruginosa on the GAC is found to be efficient for bio-degradation of the phenolic compounds and in addition they also helped in regeneration of the activated carbon systems which in turn reduce the operability cost. The extent of bio-regeneration varied between 33-66%. Haldane’s growth kinetic equation is found to be suitable to fit the specific growth rate data of P. aeruginosa.

使用固定化铜绿假单胞菌在颗粒活性炭上生物降解酚类化合物：固定化、动力学研究和微生物再生的影响

苯酚及其衍生物是工业废水中存在的主要污染物之一。在这项工作中，铜绿假单胞菌 (ATCC 9027) 已被有效地用于进行苯酚、3-氨基苯酚和儿茶酚的生物降解。为了开发一种工业上可行的技术，铜绿假单胞菌已被固定在颗粒活性炭 (GAC) 上。发现生物膜厚度在 14 到 34 微米之间。发现 GAC 上吸附的铜绿假单胞菌对酚类化合物的生物降解是有效的，此外，它们还有助于活性炭系统的再生，从而降低了操作成本。生物再生的程度在 33-66% 之间变化。发现 Haldane 的生长动力学方程适合拟合铜绿假单胞菌的特定生长速率数据。
