Developing technical alternatives to increase the volume of remediated waters is a promising way alleviate pressure on natural water basins. However, extra energy consumed in Wastewater Treatment Plants (WWTPs), mainly powered by fossil fuels, hampers this strategy. This work focuses promoting efficient upgrading treated recovering within treatment process. The approach consists recovery and in...

Advances in biotechnology are permitting significant changes in traditional plasma fractionation schemes. Increases in product purity, safety, and recovery are possible, and new products are being developed. Applications of technology to the purification of factor IX, factor X, protein C, antithrombin III, thrombin, and fibrin glue are described.

Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric iron and sulfuric acid, and these chemicals convert the insoluble sulfides of metals such as copper, nickel and zinc to soluble metal sulfates that can be readily recovered from solution. Although gold is inert...

Experimental evidence has been obtained that cryoprecipitation concentrates anti-A in mixtures of group O and group A plasma by a mechanism that does not operate in group O plasma alone. It has been concluded that the anti-A/A polysaccharide complex is less soluble during cryoprecipitation than anti-A immunoglobulin, and this complex dissociates to give free anti-A when the cryoprecipitate is r...

Pharmacists use various sources for obtaining the active pharmaceutical ingredient for compounding medications. In many cases, it is the pure drug (United States Pharmacopeia, National Formulary, or similar grade); in some cases, it can be a commercial dosage form; and, in some cases, it may be a dilution or concentrate. If the drug is not present at full strength, then adjustments may be neces...

Clotting factor concentrates (CFCs) underwent tremendous modifications during the last forty years. Plasma-derived concentrates made the replacement therapy feasible not only in the hospital but also at patients' home by on-demand or prophylactic regimen. Virucidal methods, implemented soon after hepatitis and AIDS outbreak, and purification by Mabs made the plasma-derived concentrates safer an...
