Exploring the role of rhizobacterium Ensifer meliloti on cadmium speciation and cadmium accumulation in rice (Oryza sativa L.)

 Rhizobacterium Cadmium 200X204.jpg

The project explores the role of rhizobacteria, the extracellular polymeric substances and humic substances on the speciation and accumulation of Cd in rice. This project will help us understand how the presence of the rhizobacterium affect the Cd speciation in solution, and further Cd accumulation in rice.

Oxidative stress as a mediator of bacterial resistance development towards antibiotics in the presence of sublethal levels of heavy metals

 Oxidative stress.jpg
This mechanistic project explores the influence of sub-lethal concentrations of heavy metal on bacterial resistance. The relationships between heavy metal-induced oxidative stress and damage, and bacterial resistance are thoroughly studied.

Exploring the interaction of mercury species with different diatoms

Diatom_project_200X185.jpg
This project aims to attain insights about the role of diatoms (phytoplankton group) in the Hg cycle on freshwater systems. Bioaccumulation, kinetics and prevailing mechanisms of Hg biotic transformation pathways mediated by mainly Cyclotella meneghiniana under different conditions will be determined. Physiological endpoints will also be determined under different mercury concentrations and species to understand how it affects this organism. In parallel, transcriptomic and metabolomic techniques will be applied to explore the affected pathways.

Interaction of nanoparticles with metalloproteins

AgNPs__AuNPs_200X187.jpg

  • The project studies the interaction of nanoparticles (AgNPs and AuNPs) with metalloproteins by focusing on the formation of nanoparticles-protein corona (dynamic vs. static), the behaviour of the NPs and the related consequences for the protein in terms of conformation change and its biological function.
