Sulphate assimilation provides reduced sulphur for the synthesis of cysteine, methionine, and numerous other essential metabolites and secondary compounds. The key step in the pathway is the reduction of activated sulphate, adenosine 5'-phosphosulphate (APS), to sulphite catalysed by APS reductase (APR). In the present study, [(35)S]sulphur flux from external sulphate into glutathione (GSH) and...

Bra j IE, a major allergen from oriental-mustard (Brassica juncea) seeds, has been isolated and characterized. Its primary structure has been elucidated. This protein is composed of two chains (37 and 92 amino acids) linked by disulphide bridges. The amino acid sequence obtained is closely related to that previously determined for Sin a I, an allergen isolated from yellow mustard (Sinapis alba)...

The current study is focused on controlling sulphur emissions by pre-treating coal to remove sulphur prior to combustion using the oxydesulphurisation technique. Three British coals were chosen for the study. Working with these coals gave a better insight to the oxydesulphurisation reactions for pyritic and organic sulphur. Effect of air and oxygen pressure in a fixed time interval on sulphur r...

Sulphur is an attractive cathode material with a high specific capacity of 1,673 mAh g(-1), but its rapid capacity decay owing to polysulphide dissolution presents a significant technical challenge. Despite much efforts in encapsulating sulphur particles with conducting materials to limit polysulphide dissolution, relatively little emphasis has been placed on dealing with the volumetric expansi...

Octahedral core–shell AgBr emulsions sensitized by sulphur-plus-gold with gold added at 40uC either before or after sulphur sensitization were prepared and studied. The core emulsion was sensitized with a low level of dimethylamineborane (DMAB), and it enhanced the intrinsic sensitivity and long-wavelength sensitivity of the emulsion with an unsensitized shell. Oversensitization was observed fo...

A critical review on ultrasonic studies of mustard oil gives an insight into the Physico –Chemical and Dynamic properties of mustard oils. Heart-friendly oil should be cholesteroland trans-fat free, low in saturated fats and high in monounsaturated fat (MUFA) and polyunsaturated fat (PUFA), a high smoking point and also it should have an ideal N6 to N3 acids ratio very essential for healthy hea...

In the present paper potato plants were cultivated in the presence of ammonium sulphate or elemental sulphur supplementation into the soil to reveal the effects of different sulphur forms on content of nitrogen, phosphorus, potassium, calcium, magnesium and sulphur, and yield of tubers. During the investigation of the influence of different sulphur forms on yield of potato tubers we did not obs...

The impacts of integrated soil fertility management (ISFM) in conservation agriculture need short-term evaluation before continuation its long-term practice. A split-split plot experiment with tillage (minimum tillage, MT vs. conventional CT) as the main plot, residue (20% residue, R no a control, NR) sub-plot, and compost (Trichocompost, LC; bio-slurry, BS; recommended fertilization, RD) sub-s...

Onion (Allium cepa L.) was able to use atmospheric H(2)S as sole sulphur source for growth. The foliarly absorbed H(2)S was rapidly metabolized into water-soluble, non-protein thiol compounds, including cysteine, and subsequently into other sulphur compounds in the shoots. In H(2)S-exposed plants, the accumulation of sulphur compounds in the shoots was nearly linear with the concentration (0.15...
