Abstract
Sediment microbial community plays a crucial role in aquaculture ecosystem. In aquaculture practice, rather than monoculture intensive shrimp (IS) or intensive fish (IF) patterns, polyculture of shrimp and fish (PolySF) pattern leads to a more reliable production. However, knowledge is still limited about the characteristics of sediment microbiota and its potential functions in the PolySF ponds compared to monoculture patterns (IS and IF). Herein, we collected sediment samples from these three patterns in seven cities to evaluate microbial variations among patterns. The highest oxidation reduction potential (ORP), total phosphate (TP) and total organic carbon (TOC) were detected in the PolySF pattern, representing a relatively less anoxic environment, while the highest iron (Fe) was detected in IS pattern. Proteobacteria was the most abundant phylum among three patterns, followed by Bacteroidetes and Chloroflexi. The microbial alpha diversity in the PolySF was higher than those in the IF, but lower than those in the IS. Microbial communities of these three patterns were significantly distinct from each other, and 23 distinguished taxa for each pattern were further characterized. In additional, the relative abundances of genes involved in nitrogen metabolism, fatty acid biosynthesis and carbon fixation pathways were markedly shifted. Moreover, ORP, TOC and Fe were the shaping factors for sediment microbiota, which significantly varied among three patterns. Collectively, these findings demonstrated that sediment microbial communities in the PolySF were distinctive from those in the IS and IF, which enlarged our understanding for the underlying mechanism of advances in the PolySF pattern from ecological perspective.

Combined effects of electrical current and nonsteroidal antiinflammatory drugs (NSAIDs) on microbial community in a three-dimensional electrode biological aerated filter (3DE-BAF).

Abstract
Three-dimensional electrode biological aerated filter (3DE-BAF) with particulate bioelectrode from lithium slag was used to simultaneously remove diclofenac and clofibric acid from the synthetic domestic sewage, and the combined effects of electrical current and nonsteroidal antiinflammatory drugs (NSAIDs) on microbial community was analyzed. The results indicated that (1) the average diclofenac and clofibric acid removal efficiency in the 3DE-BAF firstly increased, attained the peak of 79.40 ± 6.74% and 69.50 ± 6.26% at 0.35 A, and then decreased to 71.82 ± 4.90% and 55.92 ± 5.17% at 0.40 A, respectively; (2) the concentration of the diclofenac and clofibric acid in 3DE-BAF gradually decreased with the increase of reactor height; (3) the current intensity and space position affected the microbial structure at the different level; (4) at the optimum current intensity, Thiothrix, Flavobacteriaceae, Halothiobacillaceae, Hydrogenophaga, and Comamonadaceae accounted for the main bacterial community for removal diclofenac and clofibric acid in the 3DE-BAF.
