Antimicrobial Activity of BS4 against Gram-Negative Pathogenic Bacteria.

Worldwide, bacterial resistance is one of the most severe public health problems. Currently, the failure of antibiotics to counteract superbugs highlights the need to search for new molecules with antimicrobial potential to combat them. The objective of this research was to evaluate the antimicrobial activity of BS4 against Gram-negative bacteria.

Proteomic Study of Response to Copper, Cadmium, and Chrome Ion Stress in Strains Isolated from Andean Mine Tailings in Peru.

Mine tailings are produced by mining activities and contain diverse heavy metal ions, which cause environmental problems and have negative impacts on ecosystems. Different microorganisms, including yeasts, play important roles in the absorption and/or adsorption of these heavy metal ions. This work aimed to analyze proteins synthesized by the yeast AMJ6 (Yl-AMJ6), isolated from Andean mine tailings in Peru and subjected to stress conditions with common heavy metal ions.
