Quinone Profile

In the present study, the microbial community structure in an intermittently aerated submerged membrane bioreactor treating domestic wastewater was observed using the respiratory quinone profiles. The effects of different time interval for the aerobic and anoxic period on microbial community structure were examined with 60/90 min (Step 1) and 90/60 min (Step 2) as anoxic/aerobic periods. There was an observable slight difference in microbial community structure between Step 1 and Step 2 in the submerged membrane bioreactor. The dominant quinone types for Step 1 at both anoxic and aerobic conditions were UQ-8 followed by UQ-10 and MK-6, but those for Step 2 were UQ-8, MK-6 and MK-10(H4). The microbial diversity of Step 1 and Step 2 based on the composition of all quinones was 10.6Ð11.7 and 13.3Ð13.0 for anoxic and aerobic conditions, respectively. The present results suggest that the introduction of intermittent aeration into the submerged membrane bioreactor has little influence on the bacterial community structure.

Organic Wastewater

The BOD removal rate and microbial community structure in a solid phase aerobic bioreactor using polyvinyl alcohol gel particles as packing material for the treatment of high strength organic wastewater were investigated at various temperatures. The BOD removal rate in the bioreactor increased when the temperature increased from 20°C to 30°C, 40°C, and 50°C, but it decreased when the temperature increased from 50°C to 60°C. Higher temperature enhanced the endogenous respiration of microbes in the bioreactor. The microbial community structure in the bioreactor was analyzed with quinone profile. The experimental results showed that the microbial community structure in the bioreactor was significantly affected by temperature. The dominant quinone of the microbes inhabiting the bioreactor was ubiquinone-8 at 30°C, but that at 50°C and 60°C was menaquinone-7. It was estimated that the thermophilic Bacillus having menaquinone-7 dominated in the bioreactor at higher temperature. The microbial diversity in the bioreactor varied with temperature.
