We evaluated the antiproliferative effect of infusions from Pluchea sagittalis using the Allium cepa test. Infusions in three concentrations (2.5, 5, and 25 g dm-3) of leaves cultivated in three environments (in vitro, acclimatized growth chamber, and field) were used. Six onion bulbs were used for each of the eight treatments, and the mitotic index was obtained from 6000 cells per treatment. In conclusion, leaf infusions of P. sagittalis cultivated in the field have a high antiproliferative activity, as well as the cultivation system influences the antiproliferative potential. |

Microorganisms dominate most of Antarctic ecosystem and play a crucial role in its functioning. They are called extremophilic microorganisms with unique and versatile metabolic properties with possible biotechnological applications in several areas. The aim of the present study was to taxonomically characterize psychrophilic microorganisms from Antarctic continent samples and to screen them for antimicrobial effects. Phylogenetic analysis revealed that most isolates shared 98?100 % sequence similarity to recognized species, including those recovered previously from the Antarctica environment, which belong to the major phyla Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria (classes Alpha and Gammaproteobacteria). A total of 361 bacteria strains,... |
