We developed a new cell surface engineering system based on the PgsA anchor protein from Bacillus subtilis. In this system, the N terminus of the target protein was fused to the PgsA protein and the resulting fusion protein was expressed on the cell surface. Using this new system, we constructed a novel starch-degrading strain of Lactobacillus casei by genetically displaying alpha-amylase from ...

Growth and development of silk worm Bombyx mori L. and cocoon crop are greatly influenced by yield and nutritional quality of mulberry leaf used as feed. The nutritional status of different mulberry varieties is ascertained by its biochemical constituents. Mulberry is rich sources of protein, carbohydrate, carotenoids, lipids, ascorbic acid, anthocyanins etc Hence, five mulberry varieties viz.,...

The interactions of cell surface carbohydrates as well as of soluble glycoconjugates with their receptor proteins rule fundamental processes in cell biology. One of the supramolecular principles underlying and regulating carbohydrate recognition is multivalency. Many multivalent glycoconjugates have therefore been synthesized to study multivalency effects operative in glycobiology. This review ...

To provide scientific and technological support for the smooth development of flowers, regulation florescence, cultural management, among others, this study analyzes corresponding relationship between bioclimatology characteristics growth, development, reproductive biology A. sellowiana. Berg (Feijoa). Therefore, through optimized paraffin sections, examined floral bud differentiation in five-y...

The present investigation was designed to examine the influence of dietary fibers with differing soluble fiber compositions upon the metabolism of lipids in a hyperlipemic animal model, the Zucker fatty rat. The response to fiber was examined using a diet supplemented with cellulose, oat bran, or pectin which have a soluble/insoluble fiber ratio of 0:100, 33:66, and 100:0, respectively. These f...

Fructans, storage carbohydrates with beta-fructofuranosyl linkages, are found in approximately 15% of higher plants. The metabolic flexibility of those molecules allows them easily to polymerize and depolymerize to soluble carbohydrates according to plant development stage and environmental conditions. In this work, water-soluble carbohydrates, including fructan structure patterns, were compare...

Following fertilization of forest plantations, high accumulations of nutrients in the forest floor creates the need to assess rates of forest floor decomposition and nutrient release. The study site was a 25-year old experimental loblolly pine plantation in the North Carolina Sandhills Region. Soluble and insoluble N, P, carbohydrate and phenol-tannin fractions were determined in foliage and li...

An experiment was conducted to examine the effect that various isoenergetic diets, containing different quantities of soluble carbohydrate and fiber and different types of starch, have on nitrogen (N) balances. Six lactating dairy cows in early to midlactation consuming grass silage diets with not less than 600 g/kg total DMI as forage were used in the experiment. Four concentrates were prepare...

background: soluble microbial products (smps) have an effective role on fouling of membrane in bioreactors (mbrs). the aim of this study was to survey the role of smps on mbrs used in treating municipal wastewater. materials: lowry and phenol sulfuric acid methods were used to measure carbohydrates concentrations and protein content, respectively. biochemical oxygen demand (bod), chemical oxyge...
