Abstract
- Effect of polycyclic aromatic hydrocarbons (PAHs) on the community struc-ture of indigenous microorganisms in Gwangyang Bay sediments was investigated inMar. & Aug., 2000. Microbial community structure was analyzed using 5 ’-terminal-RFLP) method. Microbial communitystructure based on T -RFLP method revealed that community differentiated by sampl-ing period except station 1 located near the stream discharge site from Yeosu Indu-strial Complex. Even, microbial diversity was higher at stations showed relatively highconcentrations of PAHs. The microbial community structure was severely changedduring the enrichment culture with 1,000 ppm of PAHs mixture. It was also differentbetween cultivated at 8 C and 30 C. The results implied that temperature, porosity,organic content and etc were more responsible than PAHs on the microbial communitystructure.
