Constructed-wetlands, biofilms, and sedimentation are among biological filters used in mariculture wastewater treatments, however, their impacts on the distribution of benthic microbial community inorganic-nutrient fluxes have not been fully explored. This study applied 16 S rRNA high-throughput sequencing technology to investigate nutrient biofilters system. Results showed that bacterial compositions were significantly different constructed-wetland biofilm treatments (p < 0.05) relative sedimentation. The composition genes enriched with Proteobacteria (73%), Bacteroidetes (69%), Firmicutes (62%), Flavobacteria (61%) Biofilm compared (53%), (39%), (32%), (21%) constructed wetlands.

Abstract This study investigated the influence of Venus clam Cyclina sinensis bioturbation activities on total benthic microbial and phosphatase selected sediment properties: phosphorus (TP), organic nitrogen (TON), carbon (TOC) in aquaculture ponds. Sediments samples from clam-shrimp integrated pond non-clam were sampled for study, which activity (MBA) alkaline (APA), contents (TP, TON, TOC, TOM) water quality parameter (dissolved oxygen, temperature, pH, moisture content) analyzed. The p-nitrophenyl phosphate disodium (p-NPP) fluorescein diacetate (FDA) adopted to measure APA MBA, respectively. Results indicated that MBA (APA) sediments significantly increased cultured with clam/shrimp compared a pond. Phosphorus concentration varied among months (P &lt; 0.05), implying an mineralization sediments. concentrations TON TOC did not differ treatments &gt; mineralization. Correlation analyses showed there was positive correlation APA, concentration, matter content within bioturbated by clam. results suggest that, reworking mechanisms influenced sediment-microbial mineralization, thereby affecting enzyme-related activities.

Abstract Integrated Aquaculture Wastewater Bioremediation Systems (IAWBSs) are crucial for the treatment of nutrient-rich mariculture water. However, there is a lack detailed information about functional mechanisms between nitrogen (N) and phosphorus (P) genes bacterioplankton community in presence photosynthetic bacteria (PSB). This study evaluated connections N P IAWBS under influence PSB. The results showed significant improvements effluent quality, with removal efficiencies 79, 74, 83, 90, 71% NO2−-N, NO3−-N, PO43−−P, NH4+-N, CODMn, respectively. addition PSB enhanced altered microbial diversity within system, promoting expression related to cycling. Notably, associated denitrification (nirK nirS); ammonification (ureC); fixation (nifH) amoB, involved nitrification, were significantly increased after Furthermore, such as phnK, phoD, phoX, which transformation, also levels.
