Forward osmosis (FO) requires a specific membrane structure for applications like juice concentration. The phase inversion method was used to make cellulose acetate (CA) FO membranes. solvents were acetone and 1,4-dioxane. Additives included polyvinylpyrrolidone (PVP), methanol, maleic acid in the preparation of CA membrane, which it easier improve membrane's permeability. performance fabricate...

In the present study, Synechococcus elongatus and Anabaena, two cyanobacterial species were cultured using different media conditions such as ASN III, modified BG-11, BBM for enrichment of biomass lipid productivity. The experimental result clearly shows that BG 11 was efficient cost-effective medium both isolated Anabaena. influence organic carbon sources on productivity selected studied when ...

Four multiparous lactating Holstein cows fitted with rumen cannulae were fed diets varying in the amount and source of rumen-degradable carbohydrates (starch vs. sucrose) to examine their effects on rumen fermentation, nitrogen metabolism and lactation performance. A 4×4 Latin square with four diets and four periods of 28 days each was employed. Corn starch and sucrose were added to diets and c...

Sucrose and sucrose 6-phosphate synthetase were isolated from potato tubers, partially purified and their properties studied. The sucrose synthetase showed optimum activity at 45 degrees and was inhibited competitively by ADP and some phenolic glucosides. The Ki's for these inhibitors were determined. Mg(2+) was found to activate this enzyme. Activity toward UDP-glucose or ADP-glucose formation...

Extra-large pore zeolites are a small subset (21) among the whole list of 253 available. The discovery new low-glycemic sugars is very attractive as healthy additives in food field. This case 6-kestose. In present case, it appears mixture aqueous solution together with sucrose, separation being necessary. For this, we have focused on using certain adequate sizes that allow this mixture, conside...

An inducible acetylesterase (EC 3.1.1.6) that hydrolyzes ethyl acetate, an intermediate in the degradation of 2-butanone by Nocardia strain LSU-169, was purified. The polypeptide molecular weight as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was 39,500, and the enzyme molecular weight determined by sucrose density gradient centrifugation was 84,000. The purified enz...

Sucrose phosphate synthase was partially purified from spinach leaves and the effects and interactions among glucose-6-P, inorganic phosphate (Pi), and pH were investigated. Glucose-6-P activated sucrose phosphate synthase and the concentration required for 50% of maximal activation increased as the concentration of fructose-6-P was decreased. Inorganic phosphate inhibited sucrose phosphate syn...
