Development of bacterial consortia and biodegradation ability under different PAH stresses

Gel Electrophoresis (DGGE) [4]. Monitoring the microbial community by DGGE provides an effective way of visualizing the microbial changes occurring during the biodegradation process. Information regarding the composition of microbial communities throughout the culture process is useful, which will contribute to understanding the changes of microorganisms [5]. However, there were few reports on how the microbial changed during the domestication and biodegradation process of consortia under PAH pressures.
