Acclimation of nitrifying bacteria using inorganic carbon source (bicarbonate) and organic carbon source (bicarbonate + glucose) was performed in this study. Sequential batch reactors were inoculated by activated sludge (mixed culture of heterotrophic and nitrifying bacteria), and fed by synthetic wastewater contain high concentration of ammonium (1000 mg·L). Adapted nitrifying bacteria, only u...

The vacuoles of lower epidermal strips from Vicia faba exhibit an intrinsic green fluorescence when incubated in alkaline buffers. Using an alkaline-induced absorbance change as a spectrophotometric assay, the major pigment responsible for this fluorescence was isolated and identified as the flavonoid: kaempferol 3-O-galactoside, 7-O-rhamnoside. The aqueous absorption maxima were 394 and 341 na...

MNicrobiol. 11:501-505. 1963.-The effect of sea water on protein synthesis and growth of some species of Fungi Imperfecti was investigated. The dry weight of mycelia was greater from sea water medium than from distilled water medium in most instances; however...

of low correlations with the production of mineral N and crop N uptake. Recent work indicates that accumulation of amino sugar N in soil Soil testing for NO3 is currently considered the best reduces the yield response of corn (Zea mays L.) to N fertilization, and that nonresponsive sites are detectable by determination of amino option for identifying sites where N fertilization will be sugar N ...

Electrochemical processing is a cost effective and low-temperature approach suitable for the fabrication of certain unique nanostructures that are difficult to obtain by other methods. Here we report on the synthesis of nanowires and nanoporous structures with the intention to control the magnetic properties of conventional materials. Nanowires with variable sizes (diameter 15 nm microns, and l...

content (Keren et al., 1985). The range of tolerance for both sensitive and tolerant plants to soil solution This work considered the aqueous speciation of B between a soil B concentration is 0.028 to 1.39 mmol L 1. Plants are solution containing B and the tetrahedral surface B species (SH3 BOH 4 during drying of the soil. The aqueous B species were boric not sensitive to adsorbed B. Adsorption...

The constant capacitance model, a chemical surface complexation model, was applied to B adsorption on 17 soils selected for variation in soil properties. A general regression model was developed for predicting soil B surface complexation constants from easily measured soil chemical characteristics. These chemical properties were cationexchange capacity (CEC), surface area, organic carbon conten...

These data sugthe greatest negative discrepancy between average and record yields. gest that plants have high productivity potential but are To alleviate environmental stress–related yiel...

Precipitation of large crystals/agglomerates of spinel and their accumulation in the pour spout riser of a Joule-heated ceramic melter during idling can plug the melter and prevent pouring of molten glass into canisters. Thus, there is a need to understand the effects of spinel-forming components, temperature, and time on the growth of crystals in connection with an accumulation rate. In our st...
