Sugars and sugar-alcohols are demonstrated to be important constituents of the ambient aerosol water-soluble organic carbon fraction, and to be tracers for primary biological aerosol particles (PBAP). In the present study, levels of four sugars (fructose, glucose, sucrose, trehalose) and three sugar-alcohols (arabitol, inositol, mannitol) in ambient aerosols have been quantified using a novel H...

The effects of kinetin on starch and sugar levels and on (14)CO(2) and (32)P-orthophosphate labeling patterns of floated Chinese cabbage (Brassica pekinensis) leaf discs were investigated. Kinetin caused gross starch degradation. Neutral sugars were depressed by 30 to 40% in leaf tissue treated with kinetin for 24 hours. (14)CO(2) labeling of leaf discs pretreated with kinetin for 24 hours show...

abstract a large number of studies have shown that direct application of rock phosphate dose do not have enough efficiency to release phosphorus compared to chemical fertilizers. the main purpose of this study was to increase the efficiency of direct application of rock phosphate. incorporation of rock phosphate with sulfur, organic matter and inoculation with sulfur-oxidizing bacteria and phos...

Research on the influence of sex steroids: β-estradiol, testosterone and corticosteroids: cortisone, cortisole (glucocorticoids), 11-deoxycorticosterone (mineralocorticoid) and prednisolone (chemical derivative of hydrocortisone) on changes of soluble proteins, nucleic acids and reducing sugars as a content of Wolffia arrhiza (Lemnaceae) has been conducted. Wolffia has been cultivated in Bialys...

Three pineapple cultivars smooth cayenne, Tainung 17, and 19 were processed into flesh, peel, stem. Nine samples analyzed for their proximate compositions bromelain activity existed in water extracts. Pineapple fleshes rich reducing sugars soluble fiber whereas peel stem crude fiber. Stem showed higher (102–247.3 U/mg). All 18 including ethanol extracts quite effective the scavenging ABTS+- DPP...

Water soluble sugars play an important role in the flavors and irritations of cigarette sensory quality low content water discarded tobacco leaves was a huge obstacle for their application. To make better use leaves, novel roasting method with sugar supplement developed to enhance contents total flavor compounds (TFCs) tobaccos. Three main factors process namely reaction time, temperature, gluc...

Agricultural food waste is rich in cellulosic and non-cellulosic fermentable substance. In this study, we investigated the bioconversion of pineapple cell wall sugars into bioethanol by simultaneous saccharification fermentation using Saccharomyces cerevisiae ATCC 4126. Soluble insoluble were during process. Moreover, medium was for protein, moisture, ash, lignin glycerol determinations with a ...

It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels (hypoxia) and inhibitors of respiration promote bud-break in grapevines. In this study, we showed that, hypoxia increased starch hydrolysis soluble sugar consumption and up-regulat...

ABSTRACT. Teff [Eragrostis tef (Zuccagni) Trotter] is cereal grain native to Ethiopia as staple food millions of people. However, no research work has been reported for characterization with respect water-soluble total sugars and free amino acids in white brown teff grains. The main objective this study was determine (TFAA) the varieties. determined sugar contents sample extract ranged between ...

A simple procedure for determining the galacturonic acid and methanol contents of soluble and insoluble pectins, relying on enzymatic pectin hydrolysis and colorimetric quantification, is described. Pectin samples are incubated with a commercial pectinase preparation, Viscozyme, then the galacturonic acid content of the hydrolyzed pectin is quantified colorimetrically using a modification of th...
