Dietary copper sulfate (CuSO4) and tribasic copper chloride (TBCC) were examined for their effects on intestinal physiology and growth of broiler chickens. In 2 experiments (Experiments 1 and 2), day-old broiler chicks were fed 1 of 4 diets: a basal diet with no supplemental copper (Cu; negative control), a basal diet + 188 mg of Cu/kg of diet from TBCC or CuSO4, or a basal diet + subtherapeuti...

Th is article examines the status of submersible reference electrodes and presents a new design concept for submersible copper/copper sulfate (Cu/CuSO4) electrodes (CSE). In the new concept, the half-cell potential is independent of the salinity (chlorinity) of the electrolyte, the electrode is not subject to contamination, and structure-to-electrolyte voltages do not require correction to the ...

Traditional treatments of parasitic and bacterial diseases are based on chemotherapeutic compounds such as chloramine-T and CuSO4. Although many compounds are used in fish treatments, their undesirable effects are not known. In this study, glucose 6-phosphate dehydrogenase (G6PD) was purified from rainbow trout (Oncorhynchus mykiss) erythrocytes by hemolysate preparation, ammonium sulfate preci...

Among the chemical pretreatments available for pretreating biomass, the inorganic salt is considered to be a relatively new but simple reagent that offers comparable pentose (C5) sugar recoveries as the conventional dilute acid hydrolysis. This study investigated the effects of different concentrations (1.5-6.0% (v/v)) of H2O2 or Na2S2O8 in facilitating CuSO4·5H2O pretreatment for improving pen...

The analysis of (bio)available copper in complex environmental settings, including biological test media, is a challenging task. In this study, we demonstrated the potential of a recombinant Pseudomonas fluorescens-based biosensor for bioavailability analysis of CuSO4 and CuO nanoparticles (nano-CuO) in seventeen different ecotoxicological and microbiologial test media. In parallel, free Cu in ...

Cells of Ralstonia solanacearum were exposed to Cu in distilled water, and the resulting Cu-stressed non-culturable cells were inoculated to natural (non-pasteurized) and pasteurized soils in order to examine their culturability and recovery. Exposing the cells to 20 μM CuSO4 produced transitory non-culturable cells, which exhibited a remarkable recovery in culturability after incubation in the...

Performance and Cu status were measured in growing and finishing steers supplemented with different copper (Cu) concentrations and sources. Sixty Angus (n = 36) and Angus x Hereford (n = 24) steers were stratified by weight and initial liver Cu concentration within a breed and randomly assigned to treatments. Treatments consisted of 1) control (no supplemental Cu); 2) 20 mg Cu/kg DM from Cu sul...

This experiment was carried out to explore the efficiency of an individual or combined doses vitamin C (Vit. C) and E E) in alleviating biochemical, genotoxicity, pathological changes liver induced by copper sulfate (CuSO4) toxicity broiler chickens. Two hundred fifty-one-day-old chicks were haphazardly allotted into five groups (five replicates/group, ten chicks/replicate). The birds fed exper...

Artykuł przedstawia oryginalne badania związane z odzyskiwaniem miedzi ze ścieków przemysłowych. Celem badań eksperymentalnych jest odzyskiwanie sproszkowanej metalicznej o niskiej zawartości jonów metodą cementacji za pomocą złomowej elektrody żelaznej oraz do obliczenie wydajności miedzi, na którą wpływają następujące parametry: początkowe stężenia wartości pH i czas kontaktu. Eksperymenty ob...
