The impact of zinc on the reductive dissolution of hematite by the dissimilatory metal-reducing bacterium Shewanella putrefaciens CN32 was studied in batch culture mode. Experiments were conducted with hematite (2.0 g L 1) in 10 mM PIPES (pH 6.8) and H2 as the electron donor under nongrowth conditions (108 cell mL 1), spiked with zinc (0 to 0.23 mM), and incubated for 5 days. Experiments were a...


 This research was aimed to determine the effect of starter and sugar concentration on characteristics ginger wine optimal obtain best wine. study used a Completely Randomized Design with two factors. The first factor namely: 10, 15, 20% (v/v), second concentration, 20, 25, 30% (w/v). parameter tested were alcohol (ethanol) level, reducing sugar, total acid, acidity (pH), soluble solid, a...

1. A method is described for measuring the swelling pressure of solid gelatin. 2. It was found that this pressure increases rapidly between 15 degrees and 37 degrees C., and that the percentage change is nearly independent of the concentration of gelatin. 3. It is suggested that this pressure is due to the osmotic pressure of a soluble constituent of the gelatin held in the network of insoluble...

DcR3/TR6 is a secreted protein belonging to the TNFR family. It binds to Fas ligand, LIGHT, and TL1A, all of which are TNF family members. LIGHT is expressed on activated T cells. Its known receptors are TR2 and LTbetaR on the cell surface, and TR6 in solution. In the present study, we report soluble TR6-Fc or solid-phase TR6-Fc costimulated proliferation, lymphokine production, and cytotoxicit...

Abstract The study focuses on corrosion challenges for naphtha hydrotreating equipment (installed upstream of a reforming unit) caused by ammonium chloride deposits and the development adequate chemical engineering protection measures. Using an experimental setup, we investigated sublimation/desublimation at varying pressures temperatures in medium typical hydrogen-bearing gas streams flowing f...

The aim of this study was to develop celecoxib-polyvinylpyrrolidone (PVP) solid dispersion nanoparticles with and without surfactant using the supercritical antisolvent (SAS) process. The effect of different surfactants such as gelucire 44/14, poloxamer 188, poloxamer 407, Ryoto sugar ester L1695, and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) on nanoparticle formation and dissolu...

Fruit lycopene content and total soluble solid content are important factors determining fruit quality of tomatoes; however, the dynamic quantitative trait loci (QTL) controlling lycopene and soluble solid content have not been well studied. We mapped the chromosomal regions controlling these traits in different periods in F(2:3) families derived from a cross between the domestic and wild tomat...

abstract effect of different concentrations of salicylic acid on postharvest life of kiwifruit (actinidia deliciosa) cultivar hayward at 0 ±.5 °c and 90-95% rh was studied. fruits were treated with salicylic acid (0, 1 and 2 mmol/l-1) and stored at 0±.5°c for 16 weeks. fruit quality attributes assessment including firmness, total acidity, soluble solid content, ascorbic acid, antioxidant activi...
