Addition of nanoparticles into swine manure was investigated as a possible measure to mitigate the emissions of hydrogen sulfide and ammonia from swine production facilities. Bench-scale experiments were conducted, followed by room-scale tests in controlled environment chambers closely representing actual swine production rooms. Among the 12 types of commercial nanoparticles tested, zinc oxide nanoparticles achieved significant reduction in gaseous hydrogen sulfide and ammonia concentrations when mixed into the manure at a rate of 3 g zinc oxide nanoparticles per liter of manure slurry. Room-scale experiments showed that mean initial hydrogen sulfide concentrations of 596, 57 and 39 ppm measured at the pit, animal and human levels within each chamber, respectively, were reduced significantly to 5, 1 and 1 ppm, respectively, after the addition of zinc oxide nanoparticles into the manure. Effectiveness of the treatment was persistent in maintaining low hydrogen sulfide level up to 15 days after treatment application. Pig performance and manure nutrient properties were not adversely affected by the application of zinc oxide nanoparticles.

Background: Zincite (ZnO) nanoparticles are usually prepared by decomposition of zinc acetate, hot injection and heating-up method. Microbial nanoparticle production has been developed recently, since they are clean, nontoxic and cheap. Bacteria are known as environmentally friendly nanoparticle factories using cheap, renewable carbon sources. Nanometer-sized nanoparticles are talented for different applications. For example, semiconductor nanoparticles such as Sphalerite (ZnS) are used as fluorescence probes for labeling of biological tissues. These days, magnetic nanoparticles are applied routinely in magnetic resonance imaging (MRI) as contrastenhancement agents. Also, nano ZnO is useful in petrochemical industries. Objectives: The aim of this study was to produce nanoparticles such as ZnO, ZnS, and Zn by using biofilm of a resistant bacterium (i.e. Pseudomonas stutzeri) on a piece of pure zinc. Materials and Methods: P. stutzeri strain CS-2 was isolated from enriched soil containing methyl tertiary butyl ether (MTBE). Since the bacterium has many metal resistance genes, it was a good candidate for producing nanoparticles. A piece of pure zinc metal, sized 3.1cm was put on a solid medium (nutrient agar). The biofilm was isolated and analyzed by X-Ray diffractometer (XRD). The optimum environmental condition for producing nanoparticles was investigated. Moreover, antibacterial activity as well as magnetic property of the produced nanoparticles was studied. Finally, PCR reaction for specific PST gene was done. Results: Analysis by XRD showed 78.1% ZnO (sized 24 nm), 2.5% Zn (sized 44.88 nm) and 4.8% ZnS (sized 12 nm) produced by P. stutzeri. The nanoparticles showed anti-bacterial activity against some of the Gram positive and negative bacteria. In addition, the nanoparticles showed magnetic properties. The best condition for nano zinc production was at pH 7, in the light and at 37 °C. CzcC gene with 399Kb was detected from the isolated P. stutzeri. Conclusions: Although previous studies have shown that P. stutzeri is able to produce silver nanoparticles in silver salt solution, but in this study, for the first time ZnO, ZnS, and Zn nanoparticles were detected on a biofilm of zinc metal. Isolation of these nanoparticles by this method is very cost effective, non-toxic, clean and compatible to Eco (green chemistry).

AbstractFossil fuels are still a necessary and important part of modern living, keeping cars running and houses heated for example. As demands have risen and reservoirs of oil and natural gas have depleted, it has become increasingly more important to tap in to fields that were once classified as undesirable. Sour fields, fields high in acidic gases such as hydrogen sulfide and carbon dioxide, are one such option. There are many difficulties and dangers associated with working sour fields, such as toxicity of the sour gases, hydrate formation and corrosion of equipment that have prevented these resources being used in the past. Many varied methods of overcoming these problems have been developed, from removing the sour components to inhibiting their effects. This review highlights the major issues raised by sour fields as well as a wide range of solutions in use today.
