Abstract
The study was undertaken to calculated the biodegradation kinetic parameters of phenol in water and sediment estuary. Biodegradation of phenol compound in brackish water have special characteristic due to the effect of high salinity and the activities of special groups of microorganisms. The biodegradation of this compound is provided from laboratory experiments in batch reactor system. The culture for the biodegradation assay is taken from the sediment in the estuary of Mahakam River. The growth medium is made of seawater, with phenol as the substrate. The biodegradation is observed for 40 days. The initial phenol concentration in Reactor was 450.65 to 469.57 mg/l. The kinetic study showed that specific growth rate microorganism (µ) in sea water was 0.092 to 0.1356 day-1, the decay specific rate was 0.473 to 0.494 day-1, with the degradation rate was 11.19 to 11.73 mg/l.day-1.The dominant bacteria in the culture are Pseudomonas putida, Pseudomonas diminuta, Bacillus sphaericus, Enterobacter sp and pseudomonas sp. Key words: phenol, biodegradation, seawater, sediment, estuary, microorganism
