Enzymes which possess the ability to cause the adherence of Streptococcus mutans cells to a smooth glass surface were purified 1,100 times by chromatography on agarose gel followed by hydroxylapatite gel. During the purification procedures, the enzymes from strain HS6 (group a) were examined for the synthesis of water-soluble and water-insoluble polysaccharide and the ability to produce adheren...

The increasing commercial production and the broad usage of engineered nanoparticles (ENPs) have led to concerns over the potential adverse impacts of these ENPs on biota in natural environments. Silver nanoparticles (AgNPs) are one of the most important and widely used ENPs which enter natural ecosystems. In this study we examined the effects of AgNPs on growth and some physiological parameter...

to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...

Soybean contains a high concentration of carbohydrates that consist mainly of non-starch polysaccharides (NSP) and oligosaccharides. The NSP can be divided into insoluble NSP (mainly cellulose) and soluble NSP (composed mainly of pectic polymers, which are partially soluble in water). Monogastric animals do not have the enzymes to hydrolyze these carbohydrates, and thus their digestion occurs b...

McGruer and Glen P. Miller* Awater soluble pentacene, potassium 3,30-(pentacene-6,13-diylbis(sulfanediyl))dipropanoate (4), has been synthesized and characterized. The synthesis of 4 is straightforward ...

Abstract Background Recent studies indicate that amylase-trypsin inhibitors (ATIs) and certain carbohydrates referred to as FODMAPs (fermentable oligo-, di-, monosaccharides polyols) play an important role in promoting wheat sensitivity. Hitherto, no study has investigated the accumulation of ATIs during development caryopsis. We collected caryopses common cv. ‘Arnold’ at eight different grain ...
