“…Biological treatment of phenols has been an increasingly important process in pollution control [2], [19], [20]. Moreover, compared with physico-chemical methods, the biodegradation method of phenols removal is a more environmental friendly and cost effective alternative, universally preferred, because of the possibility of complete mineralization of phenol [2], [11], which results in complete conversion of a compound to its inorganic mineral constituents [1].…”

Abstract-Batch experiments were carried out to examine the biomass acclimatization during the aerobic biodegradation of 2, 4 dichlorophenol (2, 4 DCP) by Pseudomonas putida immobilized in polyvinyl alcohol (PVA) gel pellets in a bubble column bioreactor. The bacteria was acclimatized to 2, 4 DCP with concentrations of up to 200 mg/l, with and without the addition of glucose. After the acclimatization, experiments were carried out with initial 2, 4 DCP concentrations ranging from 25 to 100 mg/l. In the course of the study, a phenomenon was noticed that can be related to the effect of carbon starvation on the biodegradation ability of the bacterial cells. This paper presents the results on this phenomenon. Starved cells showed higher growth and degradation rates.

“…They have been widely applied to wastewater treatment, such as phenol degradation [14], nitrogen removal [15] and sulfate reduction [16]. The application of immobilized microorganism not only helps maintain high bacterial cell concentrations, but also increases the biological activity of the microorganisms, makes control separation easy, and protects cells against toxic substances and changes in environment factors.…”

Abstract. Phenol is the major organic compound of coking wastewater. It is of biochemical toxicity, difficult processing, difficulty to be degraded and high cost in the treatments. Microbial fuel cell (MFC) is a new type of fuel cell. It can produce electron in the process of metabolism of electricigens and export it to the external circuit. In this study, a phenol-degradable bacterium was separated and purified ( Pseudomonas sp.) at first. Then, a dual chamber type of MFC was established and phenol was selected as fuel. Afterward, we optimized the operation condition. Then, based on the character of coking wastewater, different types and concentrations of metal ions which were existed were added to research the influences of metal ion on the characteristics of electricity generation of MFC. This study showed that the strain can utilize phenol as sole carbon source, and can degrade over 98 % of phenol (1000 mg·L -1 ) within 72 h. Meanwhile, it has higher phenol tolerance up to 1750 mg·L -1 . The optimal condition is pH value of 8.0. Furthermore, Fe 3+ accelerated the electron generation and phenol decomposition, while Cu 2+ and Mn 2+ inhibited them. Additionally, as a type of surface active agent, Tween -80 influenced the best concentration is 100 mg/(L·d). Finally, sodium alginate was used as immobilized reagent and it can accelerate electricity production capacity.
