Vanadium (III) gives a greenish- yellow complex with anthranilic acid in presence of pyridine. The complex is extractable with chloroform and is used for photometric determination of vanadium by measuring the absorbance at 390 nm against a reagent blank. Beer's Law holds good in the range of 1-20 pg V/ml. Moderate amounts of Pb (II) , Ca (II) , Sr (II) , Ba (II) , Cd (II) , Mg (II) , Mn (II...

Conversion of 2-oxoadipic acid to lysine with Saccharomyces cerevisiae was accomplished in aerated and agitated fermentors under fermentation conditions resembling those used in baker's yeast process. With this process, a yeast product containing about 16 per cent hot water-extractable lysine (calculated as hydrochloride) was obtained. The conversion efficiency of 2-oxoadipic acid to lysine was...

Four soil profiles located near a copper smelter in Poland were investigated for the distribution and chemical fractions of Cu, Pb, and Zn and their mobility in relation to soil properties. Contamination with heavy metals was primarily restricted to surface horizons and the extent of contamination was 7- to 115-fold for Cu, 30-fold for Pb, and 6-fold for Zn as compared with subsurface horizons....

Extractable functions are functions where any adversary that outputs a point in the range of the function is guaranteed to “know” a corresponding preimage. Here, knowledge is captured by the existence of an efficient extractor that recovers the preimage from the internal state of the adversary. Extractability of functions was defined by the authors (ICALP’08) in the context of perfectly one-way...

The objective of this study was to evaluate effects of elemental sulfur (S) addition on soil pH and availability of macroand micronutrients during the sugarcane growing season. Sulfur application did not significantly reduce soil pH when applied at 0 to 448 kg S ha−1 due to the high soil buffering capacity. Water extractable phosphorus (P) and potassium (K) for soils receiving the highest S rat...

Rates of transamination and decarboxylation of [1-14C]leucine at a physiological concentration (0.1 mM) were measured in the perfused rat heart. In hearts from fasted rats, metabolic flux through the branched-chain 2-oxo acid dehydrogenase reaction was low initially, but increased gradually during the perfusion period. The increase in 14CO2 production was accompanied by an increase in the amoun...

Davis, Department of Civil and Environmental Engineering. Research Scientist, Rufus L. Chaney, ARS, US Department of Agriculture. Heavy metals and nutrients released from diffuse sources by u...

the antimicrobial activity of some novel ascorbic acid-metal complexes [bisascorbate complexes of copper (ii), zinc(ii), manganese (11), iron (111), cobalt(ii), lead(ii) and cadmium(ii)] was investigated. four standard strains of bacterial species - staphylococcus aureus, escherichia coli, bacillus subtilis and klebsiella pneumonia and four fungal species - trichophyton sp. penicillium sp., asp...

adsorption and water treatment of ca (ii) and mg (ii) hardness were investigated via adsorption of metal ions onto commercial polyacrylic acid hydrogel beads as a novel sorbent for metal ions (ca2+, mg2+) removal and water treatment. batch equilibrium technique was carried out under the influence of solution ph, contact time, sorbent dosage, initial metal concentration and competitive study. th...

The influence of limited proteolysis of soy protein concentrate on protein extractability, the composition of the extractable proteins, their emulsifying properties and some nutritional properties were investigated. Traditional concentrate (alcohol leached concentrate) was hydrolyzed using trypsin and pepsin as hydrolytic agents. Significant differences in extractable protein composition betwee...
