abstract   in this study, three groups of honey [natural honey; honey produced by the supplementary feeding of bees with saccharose syrup (ssh) and heat and acid (88 _ċ 2 h; 0.1% hcl) treated saccharose syrup honey (issh)] were produced and physicochemical (water content, ph, free acidity, ash, hmf, diastase activity, sucrose, protein and viscosity), microbiological and sensory properties of th...

The oil contents of rye grain seeds ranged from 0.70% (type 25) to 3.92 % (type 1). Palmitic acid contents of oils changed between 10.82% (type 26) and 22.43% (type 10). In addition, while oleic acid contents of oil samples vary between 20.61% (type 17) and 37.86% (type 3), linoleic acid contents of oils changed between 18.91% (type 3) to 54.0% (type 13). Also, linolenic acid contents of oi...

We evaluated the effect of polyacrylate polymers as immobilizing agents to aid phytostabilization of two mine soils. One soil had a very low pH (3.7) and a large Pb content, while the other was less acidic but had a greater content of Cu and Zn. Growth of perennial ryegrass (Lolium perenne L. cv. Victorian) was stimulated in polymer-amended soils. After ryegrass had been growing for 35 days, th...

Gale (2, 3) initially described the existence in bacteria of a metabolism-dependent process achieving the accumulation of freely extractable amino acids. During the studies described here a number of additional reports have appeared citing examples of amino acid (4, 5), carbohydrate (6), and phosphate (7) accumulations in bacteria. The mechanism of these accumulations is unknown. Christensen et...

Investigations were carried out on the mineral nutrients and organic food contents of seeds of three fodder Lablab purpureus, Leucaena leucocephala and Mucuna utilis for domestic consumption and industrial utilization. Leucaena leucocephala seeds contained the highest amount of lipids crude protein carbohydrates and ash contents. Lablab purpureus contained the lowest amount of lipid crude prote...

The production and application of compost potentially contaminate the environment with heavy metals. The heavy metal contents of composts must be exactly determined. Therefore, this study aims to understand the heavy metal contents in composts, using different digestion methods and to recommend the most appropriate digestion method making this measurement. Nine composts from different sources, ...
