Abstract

Aerobic granules are cultivated by a single bacterial strain, Acinetobacter calcoaceticus, in a sequencing batch reactor (SBR). This strain presents as a good phenol reducer and an efficient auto coagulator in the presence of phenol, mediated by heat-sensitive adhesins proteins. Stable 2.3-mm granules were formed in the SBR following a 7-week cultivation. These granules exhibit excellent settling attributes and degrade phenol efficiently at concentrations of 250-2,000 mg l(-1). The corresponding phenol degradation rate reached 993.6 mg phenol g(-1) volatile suspended solids (VSS) day(-1) at 250 mg l(-1) phenol and 519.3 mg phenol g(-1) VSS day(-1) at 2,000 mg l(-1) phenol concentration. Meanwhile, free A. calcoaceticus cells were fully inhibited at phenol>1,500 mg l(-1). Denaturing gradient gel electrophoresis fingerprint profile demonstrated no genetic modification in the strain during aerobic granulation. The present single-strain granules showed long-term structural stability and performed high phenol degrading capacity and high phenol tolerance. The confocal laser scanning microscopic test revealed that live A. calcoaceticus cells principally distributed at 200-250 microm beneath the outer surface, with an extracellular pol...Continue Reading
