Variation of hydrochemical conditions, with special reference to adequacy of waters as fish habitats, was traced based on selected hydrochemical parameters obtained during the studies conducted from February 2013 till February 2014 year. The results were compared with earlier studies. The sources of organic pollution were identified, and the effect of biogenic substances on the biomass, as well...

Previous studies have demonstrated the influence of calcium phosphate (CaP) mineral coating characteristics on cell attachment, proliferation, and differentiation. However, the wide range of mineral properties that can potentially influence cell behavior calls for an efficient platform to screen for the effects of specific mineral properties. To address this need, we have developed an efficient...

In classical aquaponics (coupled aquaponic systems, 1-loop systems) the production of fish in recirculating aquaculture systems (RAS) and plants in hydroponics are combined in a single loop, entailing systemic compromises on the optimal production parameters (e.g. pH). Recently presented decoupled aquaponics (2-loop systems) have been awarded for eliminating major bottlenecks. In a pilot study,...

We have isolated a mixed bacterial culture (BC-1) which is capable of degrading the gasoline oxygenate methyl t-butyl ether (MTBE). BC-1 was developed from seed microorganisms present in a chemical plant biotreater sludge. This enrichment culture has been maintained in continuous culture treating high concentrations of MTBE (120 to 200 mg/liter) as the sole carbon source in a simple feed contai...

N-Acetylglucosamine-6-sulfate sulfatase, which liberates sulfate from the N-acetylglucosamine 6-sulfate residue at the nonreducing terminus of a 3H-labeled trisaccharide prepared from heparan sulfate, was purified 136-fold from human urine. The final N-acetylglucosamine-6-sulfate sulfatase preparation was free of all lysosomal sulfatases known to act on sulfated polysaccharides and gave a singl...

Abstract Saline effluents from marine land-based aquaculture production can neither be disposed in common municipal wastewater treatment plants, nor as landfill. Furthermore, stricter environmental regulations require the reduction of phosphorous and organic matter levels environment discharges to minimize eutrophication. Chemical coagulation with FeCl3 AlSO4 is commonly used for removing suspe...
