Corn stalks are not easily degradable and thus have a low utilization rate. In this paper, highly efficient corn stalk-degrading microbial consortium, designated as SDP, was established using the strains Z22 (Bacillus subtilis), Z15 megaterium), Z08 (Aspergillus tubingensis). Moreover, fermentation conditions for enzyme production by SDP were optimized through orthogonal experiments. The Van So...

In this study, a series of zeolite-X-supported different crystal phases MnO2 (α-MnO2, β-MnO2, γ-MnO2, and σ-MnO2) catalysts were prepared via solid-state diffusion method high-heat treatment to explore their low-temperature NH3-SCR performance. All the featured typical octahedral zeolite X structures manganese dioxides species various types dispersed across support surface. Throughout entire te...

A laboratory incubation study was conducted on a temperate grassland soil to quantify the main mineral nitrogen (N) transformation rates and pathways via a15N tracing approach. Soil samples were taken from long-term phosphorus (P) trial investigate effects gross N-transformations under high low amendment. The soils incubated over 2-week period treated with ammonium-nitrate (NH4NO3) which applie...

Moss-associated nitrogen (N2) fixation is one of the main inputs new N in pristine ecosystems that are characterized by low availability. Previous studies have shown N2 inhibited inorganic (IN) inputs, but if mosses similarly affected organic (ON) remains unknown. Here, we assessed two dominant boreal forests (Pleurozium schreberi and Sphagnum capillifolium) response to different levels N, simu...

a hydrophilic macromolecular network is prepared by performing graft copolymerization of poly (sodium acrylate) chains onto salep and silica gel. the reaction parameters affecting the water absorbency of the superabsorbent composite were optimized using taguchi method. ft-ir spectroscopy and thermo gravimetric analysis (tga) were used for confirming the structure of the final product and morpho...

The increase in the cost of fertilizers and their low efficiency has led, through nanotechnology, to generation new innovative products that are sustainable improve productivity crops. Therefore, objective present study was evaluate efficacy a molybdenum nanofertilizer compared two conventional (chelate sodium molybdate) applied via foliar combined with soil fertilization NH4NO3 relation Nitrog...

Salinity and low nitrogen availability are two major abiotic stresses that often coexist disturb plant productivity. This study aimed at investigating the combined effects of salinity (0 100 mM NaCl) (0.5 5.0 NH4NO3) levels on morphological parameters, mineral status, use efficiency, photosynthesis, nitrate reductase (NR, E.C. 1.6.6.1) glutamine synthetase (GS, EC 6.3.1.2) activities Sulla carn...

El objetivo de esta investigación fue analizar la germinación esporas B. thuringiensis diverso origen aislamiento en un suelo agrícola estéril enriquecido con diferentes concentraciones glucosa como fuente carbono (C), NH4NO3 (nitrato amonio) N (nitrógeno) y extracto levadura factor crecimiento. Para lo cual las Bt, se determinó por pasteurización el método cuenta viable agar nutritivo....

Cement paste leaching and concomitant decalcification is a common cause of concrete structure deterioration. Such alterations entail microstructural changes that condition durability. This study analysed those in cement pastes exposed to accelerated decalcification, layer-by-layer, from the surface contact with agent, 6 M NH4NO3, unaltered area. The were BSEM, MIP BET whilst mineralogical nanos...
