Eleven cadmium-tolerant bacterial strains were isolated from the root zone of Indian mustard (Brassica juncea L. Czern.) seedlings grown in Cd-supplemented soils as well as sewage sludge and mining waste highly contaminated with Cd. The bacteria also showed increased tolerance to other metals including Zn, Cu, Ni and Co. The isolated strains included(More)
Silybum marianum (L.) Gaertn. (milk thistle), grown as a medicinal plant in several countries, is considered as a weed in pastures and cereal crops but also as an interesting plant for biomass production. As an additional contribution to the full exploitation of a such promising species, two Sardinian populations of S. marianum were investigated for(More)
Accessions of wild and domesticated hemp (Cannabis sativa L.) originating from Colombia, Mexico, California, Bolivia, Thailand, Afghanistan, Serbia, Hungary, south Africa and different regions of China, were studied by means of DNA polymorphisms in order to discriminate between drug and fiber types. Analysis of molecular variance (AMOVA) was used to(More)
Local populations of the pasture legumes Astragalus hamosus, Lotus edulis, Lotus ornithopodioides, Medicago ciliaris and Scorpiurus muricatus from heavy metal polluted and unpolluted sites in Sardinia were compared for tolerance to Zn, Cd and Pb in hydroponics. Tolerance of plants to heavy metals varied significantly depending on the species, origin of the(More)
The aim of this study was to compare three tests for the evaluation of the antioxidant potential of eleven plant species traditionally used to cure or to enhance animal and/or human wellbeing. In addition to the ability to modulate the production of intracellular reactive oxygen species the effect of the treatment on cell viability was also considered. In(More)
