Pteridium aquilinum (Dennstaedtiaceae), a Novel Hyperaccumulator Species of Hexavalent Chromium

Applied Sciences, 2023
Hexavalent chromium (Cr VI) is a highly toxic environmental pollutant produced as a byproduct of stainless steel manufacture and leather tanning. Several vegetal Cr VI-accumulating species have been investigated in phytoremediation, a promising technology to remove heavy metals from soils and water bodies.

Antibacterial Activity of Peruvian Tarasa Species: A Comparative Study of the Antimicrobial Effects of Extracts From Three Different Tarasa Species, T. capitata, T. operculata and T. tenuis, Against Human Pathogens. [PDF]

Int J Microbiol
The growing problem of antibiotic resistance has driven the search for new sources of antimicrobial agents. Plants, particularly those from the Malvaceae family, have showed promising potential in this field. The present study is based on Tarasa extracts, and the antimicrobial action was assessed using Staphylococcus aureus and Escherichia coli as ...
