The influence of temperature on the processing characteristics of the Atmosphere-Exposed Biofilm (AEB) system and the microbial community was investigated by employing PCR-DGGE with cloning and sequencing. Our results indicated that the chemical oxygen demand (COD) and total phosphorus (TP) removal rate increased with an increase in temperature from 10°C to 35°C, while the total nitrogen (TN) removal rate declined after first increasing with a maximum removal rate at 30°C. The temperature coefficients of COD, TN, and TP were 1.0062, 1.0727, 1.0336, respectively, indicating that the influence of temperature on the TN removal was greatest. During the entire process, significant changes were observed in the microbial community shifts. The dominant strains were Flavobacterium oncorhynchi and Parachlamydia acanthamoebae UV-7 at low-temperatures, while Uncultured bacterium TB127-12, Undibacterium parvum, and Uncultured bacterium bf1-54 were significant dominant strains at medium to high temperatures. The results have the potential to form a basis for the optimization, application, and popularization of the AEB system. [ABSTRACT FROM AUTHOR] |
