Adsorption of Toxic Metal Ions from Solution by Inactivated Cells of Larrea Tridentata
Larrea tridentata (creosote bush) is a plant that grows abundantly in the desert environment. This desert plant has been found naturally growing in heavy-metal contaminated soils. Previous experiments showed that the inactivated biomass of creosote bush was able to adsorb Cu(II) ions from aqueous solutions. The copper-binding capacity of the bush biomass that grows in heavy-metal uncontaminated...
متن کاملENHANCED METAL-BINDING CAPACITY OF NaOH TREATED LARREA TRIDENTATA LEAF TISSUE
Larrea tridentata, or creosote bush, is a common desert plant that inhabits the Chihuahuan Desert. Due to its great abundance and high growth tolerance of heavy metal-contaminated soils, it was chosen as the primary candidate for this study. Previous experiments conducted on inactivated and untreated sodium hydroxide (NaOH) Larrea tridentata leaf tissues showed that it effectively bound metal i...
متن کاملAbsorption of copper(II) by creosote bush (Larrea tridentata): use of atomic and x-ray absorption spectroscopy.
Larrea tridentata (creosote bush), a common North American native desert shrub, exhibits the ability to take up copper(II) ions rapidly from solution. Following hydroponic studies, U.S. Environmental Protection Agency method 200.3 was used to digest the plant samples, and flame atomic absorption spectroscopy (FAAS) was used to determine the amount of copper taken up in different parts of the pl...
متن کاملCreosote Bush (Larrea tridentata) Improves Insulin Sensitivity and Reduces Plasma and Hepatic Lipids in Hamsters Fed a High Fat and Cholesterol Diet
Creosote bush, Larrea tridentata (Sesse y Moc. Ex DC, Zygophyllaceae) is a shrub found in the deserts of Northern Mexico and Southwestern United States. In traditional medicine, it is used to treat a variety of illnesses including type 2 diabetes. The present study aims to investigate the effects of creosote bush ethanolic extract on plasma and liver parameters associated with the metabolic syn...
متن کاملThe association of native and non-native annual plants with Larrea tridentata (creosote bush) in the Mojave and Sonoran Deserts
Creosote bushes (Larrea tridentata) form islands of fertility that influence annual plant abundances in desert ecosystems, and the distribution of native and non-native annuals with respect to creosote may differ. We established plots on the north and south facing sides of L. tridentata in the Mojave and Sonoran Deserts within four different microhabitats spanning from under the shrub canopy in...
