Whole-plant carbohydrate partitioning involves the assimilation of carbon in leaves and its translocation to nonphotosynthetic tissues. This process is fundamental to plant growth and development, but its regulation is poorly understood. To identify genes controlling carbohydrate partitioning, we isolated mutants that are defective in exporting fixed carbon from leaves. Here we describe psyched...

The objectives of this study were to clarify whether the wild yeast isolated from fruits and humus is suitable forbread making. Using colony PCR, assimilation of carbohydrate and 18S rRNA sequencing, seven strains fromamong 70 samples were identified as Saccharomyces cerevisiae. The ethanol and CO2 production by the 10-2 wild yeast strain were highest among the strains. The pH and utilized gluc...

From studies employing the techniques of manometry, Clifton (1950) has further developed the concept first enunciated by Kluyver (1930, 1931) that the energy resident in a substrate molecule would not provide a propitious criterion for predicting the extent of its assimilability by the bacterial cell. He noted, for example, the same degree of assimilation with the monobasic organic compounds, l...

In the halophytic species Mesembryanthemum crystallinum, the induction of crassulacean acid metabolism (CAM) by salinity requires a substantial investment of resources in storage carbohydrates to provide substrate for nocturnal CO(2) uptake. Acclimation to salinity also requires the synthesis and accumulation of cyclitols as compatible solutes, maintenance of root respiration, and nitrate assim...

Cell wall proteins with sialidase activity are involved in carbohydrate assimilation, adhesion to mucosal surfaces, and biofilm formation. Gardnerella spp. inhabit the human vaginal microbiome encode up three enzymes, two of which suspected be cell associated. Here, we demonstrate that gene encoding extracellular NanH3 is found almost exclusively piotii closely related species genome sp. 3, its...

Increased efficiency of nutrient utilization can potentially be gained with increased starch digestion in the small intestine ruminants. However, ruminants have quantitative limits extent disappearance intestine. The objective is to explore nutritional and physiological constraints that contribute limitations carbohydrate assimilation ruminant Altered digesta composition passage rate intestine,...

The growth of trees and other plants occurs through the interactive combination of photosynthesis and carbon (and other nutrient) assimilation. Photosynthesis enables the production of carbohydrate that can then be used in growing foliage, whereby photosynthesis is enabled. We construct a mathematical model of carbon uptake and storage, which allows the prediction of the growth dynamics of tree...

The correct identification of Candida species is of great importance, as it presents prognostic and therapeutical significance, allowing an early and appropriate antifungical therapy. The purpose of this study was to identify isolates of Candida spp. from oral mucosa of 38 patients with oral candidosis evaluated in 2004 by phenotypic methods and PCR, discriminating C. albicans from the other Ca...

Nitrate reductase, the first enzyme in nitrate assimilation, is located at the crossroad of two energy-consuming pathways: nitrate assimilation and carbon fixation. Light, which regulates the expression of many higher-plant carbon fixation genes, also regulates nitrate reductase gene expression. Located in the cytosol, nitrate reductase obtains its reductant not from photosynthesis but from car...
