Foreword Livestock production is the predominant industry in Tibet Autonomous Region of China with significant numbers of yaks, cattle, horses, sheep and goats raised under various production systems. Little is known about the mineral and trace element status of these animals although it is suspected that they may be at risk from iodine and selenium deficiency. This report is the outcome of a c...

The hybrid Pseudomonas cepacia strain JHR22 was tested for its ability to degrade Aroclor 1221 in soil. The influence of supplements--mineral salts and trace elements--on the degradation was investigated. Disappearance of Aroclor 1221 congeners, occurrence of metabolites, and release of chloride were measured under different conditions. After 45 days the hybrid organism, strain JHR22, was still...

Nutritional minerals have been sourced from the Great Salt Lake (GSL) and provided to domestic and international markets since 1969. Endorheic properties of the lake leading to high mineral concentrations, in conjunction with the vastness of the lake, set the GSL apart as the most logical location for nutritional mineral extraction in the world. In spite of the vast abundance of mineral-based r...

Mineral nutrition research in recent years has focused on reducing mineral excretion; however, very little work has focused on accurate determination of mineral requirements. To more accurately define and understand mineral requirements, it is essential that a better understanding of mineral absorption mechanisms and their regulation be achieved. This is particularly important because the cost ...

The role of trace elements in biological systems has been described in several animals. However, the knowledge in fish is mainly limited to iron, copper, manganese, zinc and selenium as components of body fluids, cofactors in enzymatic reactions, structural units of non-enzymatic macromolecules, etc. Investigations in fish are comparatively complicated as both dietary intake and waterborne mine...
