Aerobic granulation of pure bacterial strain

ADAV Sunil S., LEE Duu-Jong

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 4, Pages 461-467 doi: 10.1007/s11783-008-0066-0

Abstract: The objective of this study is to cultivate aerobic granules by pure bacterial strain, , in a sequencing batch reactor. Stable granules sized 2.0–2.2 mm were formed in the reactor after a five-week cultivation. These granules exhibited excellent settling attributes, and degraded phenol at rates of 1.49 and 1.19 g phenol/(g VSS·d) at 250 and 1500 mg/L of phenol concentration, respectively. Confocal laser scanning microscopic test results show that was distributed over the initial small aggregates, and the outer edge of the granule was away from the core regime in the following stage.
