A new primer set was designed to specifically amplify ca. 1,100 bp of aoxB genes encoding the As(III) oxidase catalytic subunit from taxonomically diverse aerobic As(III)-oxidizing bacteria. Comparative analysis of AoxB protein sequences showed variable conservation levels and highlighted the conservation of essential amino acids and structural motifs. AoxB phylogeny of pure strains showed well...
Potassium Permanganate (KMnO 4 ), which is a kind of strong oxidizer, used in water production. As KMnO containing Manganese, the Manganese concentration may get higher by overdosing additives, however, there isn’t any conclusion dosing interval present study. This paper sand as catalyst and trying to determine optimal amount oxidizers, ratio limit. The results showed that could remove manganes...
The distribution of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in cattle, swine, and chicken manure compost was analyzed. PCR-denaturing gradient gel electrophoresis (DGGE) showed that a Candidatus Nitrososphaera gargensis-like sequence dominated in cattle manure compost, while few AOA were detected in other composts. In the case of AOB, Nitrosomonas-like sequences were detected with hi...
Sulfobacillus acidophilus Norris et al. 1996 is a member of the genus Sulfobacillus which comprises five species of the order Clostridiales. Sulfobacillus species are of interest for comparison to other sulfur and iron oxidizers and also have biomining applications. This is the first completed genome sequence of a type strain of the genus Sulfobacillus, and the second published genome of a memb...
Manganese oxides occur in a wide range of environmental settings either as coatings on rocks, sediment, and soil particles, or discrete grains. Although the production biologically mediated Mn is well established, relatively little known about microbial-specific strategies for utilizing environment how these affect morphology, structure, chemistry associated mineralizations. Defining such chara...
a simple, rapid and efficient dispersive liquid–liquid microextraction by use of ionic liquid (il-dllme)method, followed by flame atomic absorption spectrometry (faas) was developed for the preconcentrationand determination of palladium in water samples. in this method, an appropriate mixture of acetone and octylmethyl imidazolium hexafluorophosphate was injected rapidly into the aqueous sample...
بیماری های ناشی از مسمومیت غذایی هنوز یک نگرانی عمومی برای مصرف کنندگان مواد غذایی و صنایع فعال در این زمینه هستند.(1) با توجه به درخواست روز افزون مشتریان، تمایل به استفاده از ترکیبات طبیعی دارای خاصیت آنتی باکتریال به عنوان نگهدارنده در مواد غذایی بیشتر شده است.(2) گلنار با نام علمی punica granatumدر طب سنتی به عنوان درمان اسهال بکار میرود و گفته می شود که غنی از ترکیبات تانن می باشد.(1)در ا...
The present paper investigated a preparation of Nano sized Mg0.2Fe0.8O by eco-friendly chemical combustion synthesis using magnesium and iron nitrates as oxidizers and the glycine as a fuel to drive the reaction. Powder characterization was carried out by X-ray diffraction (XRD) to estimate crystallite size, Particle Size Analyzer (PSA), Thermal gravimetric analyzer (TGA) for determining sample...
51) Int. Cl. (57) A mechanochemical oxidation process that allows relatively benign oxidizers to be used for the production of at least partially oxidized graphite, and a method of preparing a carbon fiber using oxidized graphite and a fiber component. Partially oxidized graphite is fully dispersible in water and can be used to prepare thin films with conductivities rivaling pure graphite. This...
