In this study, the ecotechnology artificial floating islands (AFIs), colonized by Eichhornia crassipes, have been tested as a tool for water quality improvement of fishponds. The experiment was carried out in semi-intensive production during grow-out period Nile tilapia, comprising one cycle. It completely randomized with two treatments (with and without AFIs) three replications. Temperature, d...
The Amazon River drains a diverse tropical landscape greater than 6 million km2, culminating in the world's largest export of freshwater and dissolved constituents to ocean. Here, we present organic carbon (DOC), inorganic nitrogen (DON, DIN), orthophosphate (PO43?), major trace ion concentrations fluxes from using 26 samples collected over three annual hydrographs. Concentrations were predomin...
The treatment of nutrients and organic contaminants in wastewater using microalgae has drawn significant interest thanks to its advantages environmental friendliness, low cost, CO2 emission reduction, recycling valuable biomass. Among other algae species, Chlorella sp. showed good vitality, simplicity cultivation, high nutrient accumulation harsh conditions wastewater. In this study, vulgaris w...
The concentrations of dissolved inorganic nitrogen (DIN; NO2−–N, NH3–N, and NO3−–N), PO43−–P, dissolved oxygen (DO), chemical oxygen demand (COD), five-day biological oxygen demand (BOD5), oil, Si, and seven heavy metals (Hg, Cr, Cu, As, Zn, Pb, and Cd) in seawater from the Dongzhaigang National Mangrove Nature Reserve of China in 2013 were determined. Except for the concentrations of the COD, ...
Matrix vesicle-mediated mineralization is an orchestrated sequence of ultrastructural and biochemical events that lead to crystal nucleation and growth. The influx of phosphate ions into the matrix vesicle is mediated by several proteins such as TNAP, ENPP1, Pit1, annexin and so forth. The catalytic activity of ENPP1 generates pyrophosphate (PPi) using extracellular ATPs as a substrate, and the...
