%X Phospholipid fatty acids (PLFAs) were applied to determine changes in microbial community structures af-fected by the bioturbation of Bellamya aeruginosa. The results showed that the total biomass of PLFAs had a distinguished increase in treatments contained snails comparing with the control group. Furthermore, it was highly related to the content of TOC, r = 0.541 ( P <0.05). The ratio of bacteria/fungus changed remarkably during the experiment, the ratio of bacte-ria/fungus in mid-density treatment is significantly higher than the other treatments ( P <0.05), indicating that bacteria grew more quickly than fungus and the bacteria biomass increased significantly in Mid-density condition. Principle components analysis (PCA) of PLFAs profiles demonstrated that the microbial community structures were similar in low and high den-sity treatments and the control, and no obvious changes were observed; while in Mid-density treatments (196ind/m2), mi-crobial community structures had varied apparently.
