Eucalyptus Leaves as Potential Indicators of Gold Mine in Indonesia

Natural gold particles in Eucalyptus leaves and their relevance to exploration for buried gold deposits

Eucalyptus trees may translocate Au from mineral deposits and support the use of vegetation (biogeochemical) sampling in mineral exploration, particularly where thick sediments dominate. However, biogeochemistry has not been routinely adopted partly because biotic mechanisms of Au migration are poorly understood. For example, although Au has been previously measured in plant samples, there has ...

Heavy Metals Tolerance Potential of Fungi Species Isolated from Gold Mine Tailings in Ghana

Introduction: Heavy metal contamination has necessitated a less expensive and non-destructive clean-up technique such as mycoremediation. This study aimed to isolate, identify, and evaluate the tolerance of fungi species in different concentrations of heavy metals for their potential use in bioremediation. Materials and Methods: Fungi were isolated by serial dilution and spread plate technique...

Natural products as a gold mine for arthritis treatment.

Arthritis, an inflammation of the joints, is usually a chronic disease that results from dysregulation of pro-inflammatory cytokines (e.g. tumour necrosis factor and interleukin-1beta) and pro-inflammatory enzymes that mediate the production of prostaglandins (e.g. cyclooxygenase-2) and leukotrienes (e.g. lipooxygenase), together with the expression of adhesion molecules and matrix metalloprote...

Bioherbicidal potential of essential oil from leaves of Eucalyptus tereticornis against Echinochloa crus - galli L

The present study was undertaken to explore the bioherbicidal potential of essential oil(EO)(25 to 250μg/ml) from Eucalyptus tereticornis against one of the major weed of rice (Oryza sativa L.), i.e. Echinochloa crus – galli L. considering percent germination, root length and shoot length development chlorophyll, protein and carbohydrate content and percent cellular respiration). Studies reveal...
