The water-insoluble fraction, obtained after successive treatment of an insoluble fraction of a buffer-homogenate of Zea mays L. hybrid B73 x Mo 17 shoots with 3 molar LiCl and hot water, was treated with alpha-amylase to remove starch. This fraction has been subjected to sugar composition analysis and the major glycosidic linkages were determined. The results suggest that the water-insoluble f...

The relationship between the solubility, crystallinity, and length of the unit chains of plant storage α-glucan was investigated by manipulating the chain length of α-glucans accumulated in a rice mutant. Transgenic lines were produced by introducing a cDNA for starch synthase IIa (SSIIa) from an indica cultivar (SSIIa (I), coding for active SSIIa) into an isoamylase1 (ISA1)-deficient mutant (i...

The use of recombinant proteins may represent an alternative model to inactivated vaccines against hepatitis A virus (HAV). The present study aimed to express the VP1 protein of HAV in baculovirus expression vector system (BEVS). The VP1 was expressed intracellularly with molecular mass of 35 kDa. The VP1 was detected both in the soluble fraction and in the insoluble fraction of the lysate. The...

the possibility of fractional replacement of gelatin in pastille with either soluble, fractions or whole persian gum and the effects of olibanum gum addition on some sensory and physical properties of pastille were evaluated. findings revealed that persian gum either alone or along with high levels of sucrose could not result in gelation, whereas its insoluble part addition led to some gelation...

theaim of the current study was to assess effects of different levels of origanum vulgare (0, 250, 500, 750 and 1000 mg/l) on kinetics of gas production, some ruminal digestion and fermentation parameters, methane production and also to determine its potential in controlling rumen acidosis using in vitro method in four separate phases. in the first phase, the asymptote of gas production (a) and...

The killer toxin from Pichia membranifaciens CYC 1106, a yeast isolated from fermenting olive brines, binds primarily to the (136)-b-D-glucan of the cell wall of a sensitive yeast (Candida boidinii IGC 3430). The (136)-b-D-glucan was purified from cell walls of C. boidinii by alkali and hot-acetic acid extraction, a procedure which solubilizes glucans. The major fraction of receptor activity re...

introduction: pragmates australis (pa) (common reed) is a riverside perennial grass found in wetlands throughout temperate and tropical regions of the world. pa grows in many wetlands around rivers in iran. animal feed restriction is the main problem of iranian animal production systems and this feed resource can be fed to native livestock especially in rural areas. ensiling pa could improve it...

The synaptic portion of a muscle fiber's basal lamina sheath has molecules tightly bound to it that cause aggregation of acetylcholine receptors (AChRs) on regenerating myofibers. Since basal lamina and other extracellular matrix constituents are insoluble in isotonic saline and detergent solutions, insoluble detergent-extracted fractions of tissues receiving cholinergic input may provide an en...
